+# Engine Specifications
+
+This project stores SQL autocomplete vocabulary in normalized engine specifications under `structures/engines/`.
+
+## How Version Deltas Work
+
+The specification model uses a **base + delta** strategy:
+
+- `common.functions` and `common.keywords` contain the shared baseline for that engine.
+- `versions..functions_remove` and `versions..keywords_remove` remove entries that are not valid for an older major version.
+
+We intentionally keep newer capabilities in `common` and apply only removals for older majors.
+
+## Version Resolution Rule
+
+At runtime, vocabulary resolution uses:
+
+1. exact major match when available;
+2. otherwise, the highest configured major version `<=` the server major.
+
+Example: if PostgreSQL server major is `19` and the highest configured major is `18`, version `18` is used.

## 1. Executive Summary
-### ✅ What is Solid and Complete
+### ✅ Solid and Stable Areas
| Area | Status |
|------|--------|
-| **SQLite Engine** | Most mature. Full CRUD for Table, Column, Index, Foreign Key, Record, View, Trigger. Check constraints supported. |
-| **MySQL/MariaDB Engines** | Strong parity. Full CRUD for Table, Column, Index, Foreign Key, Record, View, Trigger, Function. |
-| **Connection Management** | SSH tunnel support (MySQL, MariaDB, PostgreSQL), session lifecycle, multi-database navigation. |
-| **UI Explorer** | Tree navigation for databases, tables, views, triggers, procedures, functions, events. |
-| **Table Editor** | Column editor, index editor, foreign key editor with full CRUD. |
-| **Record Editor** | Insert, update, delete, duplicate records with filtering support. |
-| **SQL Autocomplete** | Keywords, functions, table/column names. |
-| **SSH Tunnel Testing** | Comprehensive test coverage for MySQL, MariaDB, and PostgreSQL SSH tunnel functionality. |
-
-### ⚠️ Partially Implemented (Risky)
-
-| Area | Issue |
-|------|-------|
-| **PostgreSQL Engine** | Schema support incomplete. No Function class. |
-| **Procedure/Event UI** | Explorer shows them but no editor panels exist. |
+| **SQLite Engine** | Most mature path with complete day-to-day table/record workflows. |
+| **MySQL/MariaDB Core** | Strong parity for tables, columns, indexes, foreign keys, records, views, triggers, functions. |
+| **UI Core Editors** | Table, columns, indexes, foreign keys, records, and view editor are operational. |
+| **Explorer Navigation** | Databases, tables, views, triggers, procedures, functions, and events are visible in tree explorer. |

+
+### 🟡 Partial / Under Validation
-### ❌ Completely Missing
+| Area | Current State |
+|------|---------------|
+| **PostgreSQL Function** | Class + CRUD methods exist, context introspection exists, still considered under validation. |
+| **PostgreSQL Procedure** | Class + CRUD methods exist, context introspection exists, still considered under validation. |
+| **Check Constraints (MySQL/MariaDB/PostgreSQL)** | Engine classes and introspection exist, cross-version validation still needed. |
+| **Connection Reliability Features** | Persistent connection statistics, empty DB password support, and TLS auto-retry are implemented and need longer real-world validation. |
+
+### ❌ Missing / Not Implemented
| Area | Notes |
|------|-------|
-| **Schema/Namespace Management** | PostgreSQL schemas visible but no CRUD. |
-| **User/Role Management** | Not implemented for any engine. |
-| **Privileges/Grants** | Not implemented. |
-| **Sequences** | Not implemented (PostgreSQL). |
-| **Materialized Views** | Not implemented. |
-| **Partitioning** | Not implemented. |
-| **Import/Export/Dump** | Not implemented. |
-| **Database Create/Drop** | Not implemented in UI. |
+| **Function/Procedure UI Editors** | Explorer lists objects, but dedicated create/edit UI is still missing. |
+| **Database Create/Drop UI** | No complete create/drop workflow across engines. |
+| **Schema/Sequence Management** | PostgreSQL schema/sequence CRUD is not available. |
+| **User/Role/Grants** | Not implemented for any engine. |
+| **Import/Export** | Dump/restore and structured data import/export not implemented. |

+# Versioning Policy
+
+## 1. Purpose
+
+This document defines how to bump versions for any project or
+repository. If a repository requires different rules, it **MUST**
+explicitly define a local override document.
+
+------------------------------------------------------------------------
+
+## 2. Version Format
+
+All projects **MUST** use the following format:
+
+ MAJOR.MINOR.PATCH
+
+Optional pre-release suffix:
+
+ -alpha.N
+ -beta.N
+ -rc.N
+
+### Examples
+
+ 1.4.2
+ 2.0.0-rc.1
+ 0.5.0-alpha.3
+
+------------------------------------------------------------------------
+
+## 3. Bump Rules
+
+### 3.1 PATCH (x.y.Z)
+
+Use PATCH for backward-compatible bug fixes and safe internal
+improvements that do **NOT** change public behavior or contracts.
+
+#### Good examples
+
+ 1.0.0 → 1.0.1 (bug fix)
+ 1.2.3 → 1.2.4 (security fix)
+ 2.4.1 → 2.4.2 (internal refactor without behavior change)
+
+#### Bad examples
+
+ 1.2.3 → 1.2.4 while changing API response schema
+ 1.2.3 → 1.2.4 while removing a feature
+
+------------------------------------------------------------------------
+
+### 3.2 MINOR (x.Y.0)
+
+Use MINOR for backward-compatible feature additions.
+
+#### Good examples
+
+ 1.0.1 → 1.1.0 (new optional feature)
+ 2.3.4 → 2.4.0 (new endpoint, old clients still work)
+ 3.2.5 → 3.3.0 (new configuration option, not required)
+
+#### Bad examples
+
+ 1.2.0 → 1.3.0 if existing clients break
+ 1.2.0 → 1.3.0 when default behavior changes incompatibly
+
+------------------------------------------------------------------------
+
+### 3.3 MAJOR (X.0.0)
+
+Use MAJOR for breaking changes.
+
+A change is breaking if it may require modifications in consumers.
+
+#### Good examples
+
+ 1.4.3 → 2.0.0 (breaking API change)
+ 2.1.0 → 3.0.0 (removed feature)
+ 3.5.2 → 4.0.0 (database schema incompatible change)
+ 5.0.0 → 6.0.0 (default behavior changed incompatibly)
+
+#### Bad examples
+
+ 1.4.3 → 2.0.0 for a simple bug fix
+ 1.4.3 → 2.0.0 for adding an optional feature
+
+------------------------------------------------------------------------
+
+## 4. Reset Rules (Mandatory)
+
+When bumping:
+
+- MAJOR → reset MINOR and PATCH to 0
+- MINOR → reset PATCH to 0
+- PATCH → no reset required
+
+#### Good examples
+
+ 1.0.1 → 1.1.0
+ 1.1.9 → 2.0.0
+ 2.3.4 → 2.3.5
+
+#### Forbidden by policy
+
+ 1.0.1 → 1.1.2
+ 1.2.3 → 2.1.0
+
+Correct sequence:
+
+ 1.0.1 → 1.1.0 → 1.1.1 → 1.1.2
+
+------------------------------------------------------------------------
+
+## 5. Pre-1.0.0 Versions (0.x.y)
+
+Before 1.0.0, breaking changes are expected more frequently.
+
+### Recommended behavior
+
+- Breaking change → bump MINOR (0.3.4 → 0.4.0)
+- Bug fix → bump PATCH (0.3.4 → 0.3.5)
+
+### Pre-release usage
+
+ 0.4.0-alpha.1 → early unstable version
+ 0.4.0-beta.1 → feature-complete preview
+ 0.4.0-rc.1 → release candidate, only bug fixes allowed
+
+Nightly builds **SHOULD** use `-alpha.N` (or `-dev.N`) and **MUST NOT**
+be published as stable releases.
+
+------------------------------------------------------------------------
+
+## 6. Breaking Change Definition
+
+A change is breaking if it can require changes in consumers, including:
+
+- Public API modification
+- Response structure change
+- Configuration requirement change
+- Removed functionality
+- Default behavior change
+- Schema incompatibility
+- Environment variable changes (new required vars, renamed/removed
+ vars)
+
+### Desktop / PyInstaller-specific breaking changes
+
+Also considered breaking:
+
+- Configuration directory changes without migration
+- Workspace/session schema changes without backward compatibility
+- Removed or renamed CLI flags
+- Removed or renamed required resource files (themes, templates, etc.)
+
+If in doubt, treat the change as breaking and bump MAJOR (or MINOR in
+0.x.y).
+
+------------------------------------------------------------------------
+
+## 7. No Skipping Rule
+
+Versions **MUST** follow logical semantic transitions.
+
+#### Good examples
+
+ 1.2.3 → 1.2.4
+ 1.2.4 → 1.3.0
+ 1.3.0 → 2.0.0
+
+#### Forbidden by policy
+
+ 1.2.3 → 1.4.7
+ 1.0.1 → 1.1.2 (without intermediate steps)
+
+All increments **MUST** be semantically justified.

+
+Notes:
+- **MySQL triggers are row-level only** (the syntax defines action time BEFORE/AFTER “for each row”).
+- **PostgreSQL supports INSTEAD OF triggers on views** and supports `TRUNCATE` triggers.
+- **SQLite supports TEMP triggers, `IF NOT EXISTS`, `UPDATE OF col...`, `WHEN expr`, and row-level only.**
+- **Oracle has very broad trigger types** (DML, DDL, system/database events, compound triggers, etc.); the UI above is the “DML view” subset unless you decide to expose advanced Oracle-specific triggers.
+
+---
+
+## Engine-specific clauses (what to show/hide)
+
+### MySQL
+- `DEFINER = user` ✅
+- `FOLLOWS other_trigger` / `PRECEDES other_trigger` ✅
+- Timing: `BEFORE` / `AFTER` ✅
+- Events: `INSERT` / `UPDATE` / `DELETE` ✅
+- Level: **ROW only** ✅
+
+### MariaDB
+- `DEFINER = ...` ✅
+- `OR REPLACE` ✅ and `IF NOT EXISTS` ✅
+- `FOLLOWS` / `PRECEDES` ✅
+- Timing/events/level like MySQL (ROW only) ✅
+
+### PostgreSQL
+- `CREATE [OR REPLACE] [CONSTRAINT] TRIGGER ...` ✅
+- Timing: `BEFORE` / `AFTER` / `INSTEAD OF` ✅
+- Events: includes `TRUNCATE` ✅
+- `UPDATE OF col...` ✅
+- `FOR EACH ROW` / `FOR EACH STATEMENT` ✅
+- `WHEN (condition)` ✅
+- `REFERENCING ... TABLE AS ...` (transition tables) ✅
+- Deferrable constraint triggers ✅
+
+### Oracle (DML-focused subset)
+- `CREATE OR REPLACE TRIGGER ...` ✅
+- Timing points (row/statement) ✅
+- `INSTEAD OF` triggers on views ✅
+- `FOLLOWS` / `PRECEDES` ✅
+- `ENABLE` / `DISABLE` ✅
+- Plus **many Oracle-only trigger kinds** (schema/database/system/DDL), which you can keep out of the “common UI”.
+
+### SQLite
+- `CREATE [TEMP|TEMPORARY] TRIGGER [IF NOT EXISTS] ...` ✅
+- Timing: `BEFORE` / `AFTER` / `INSTEAD OF` ✅
+- `UPDATE OF col...` ✅
+- `FOR EACH ROW` only ✅
+- `WHEN expr` ✅
+- No definer/security/order controls.
+
+---
+
+## Sources (for your SQL generator / docs)
+- MySQL `CREATE TRIGGER`: DEFINER, timing/events, and FOLLOWS/PRECEDES order clause.
+- MySQL security note: triggers have no `SQL SECURITY` characteristic; they always execute in definer context.
+- MariaDB `CREATE TRIGGER`: OR REPLACE, IF NOT EXISTS, DEFINER, FOLLOWS/PRECEDES.
+- PostgreSQL `CREATE TRIGGER`: OR REPLACE, CONSTRAINT triggers, TRUNCATE, UPDATE OF, ROW/STATEMENT, WHEN, transition tables.
+- SQLite `CREATE TRIGGER`: TEMP, IF NOT EXISTS, INSTEAD OF, UPDATE OF, FOR EACH ROW, WHEN.

+ summary: AES_ENCRYPT() and AES_DECRYPT() allow encryption and decryption of data
+ using
+ description: 'AES_ENCRYPT() and AES_DECRYPT() allow encryption and decryption
+ of data using the official AES (Advanced Encryption Standard) algorithm, previously
+ known as "Rijndael." Encoding with a 128-bit key length is used (from MariaDB
+ 11.2.0, this is the default, and can be changed). 128 bits is much faster and
+ is secure enough for most purposes. AES_ENCRYPT() encrypts a string str using
+ the key key_str, and returns a binary string. AES_DECRYPT() decrypts the encrypted
+ string and returns the original string. The input arguments may be any length.
+ If either argument is NULL, the result of this function is also NULL. Because
+ AES is a block-level algorithm, padding is used to encode uneven length strings
+ and so the result string length may be calculated using this formula: 16 x (trunc(string_length
+ / 16) + 1) If AES_DECRYPT() detects invalid data or incorrect padding, it returns
+ NULL. However, it is possible for AES_DECRYPT() to return a non-NULL value (possibly
+ garbage) if the input data or the key is invalid. MariaDB starting with 11.2
+ -------------------------- From MariaDB 11.2, the function supports an initialization
+ vector, and control of the block encryption mode. The default mode is specified
+ by the block_encryption_mode system variable, which can be changed when calling
+ the function with a mode. mode is aes-{128,192,256}-{ecb,cbc,ctr} for example:
+ "AES-128-cbc". AES_ENCRYPT(str, key) can no longer be used in persistent virtual
+ columns (and the like).'

+ description: Tries to obtain a lock with a name given by the string str, using
+ a timeout of timeout seconds. Returns 1 if the lock was obtained successfully,
+ 0 if the attempt timed out (for example, because another client has previously
+ locked the name), or NULL if an error occurred (such as running out of memory
+ or the thread was killed with mariadb-admin kill). A lock is released with RELEASE_LOCK(),
+ when the connection terminates (either normally or abnormally). A connection
+ can hold multiple locks at the same time, so a lock that is no longer needed
+ needs to be explicitly released. The IS_FREE_LOCK function returns whether a
+ specified lock a free or not, and the IS_USED_LOCK whether the function is in
+ use or not. Locks obtained with GET_LOCK() do not interact with transactions.
+ That is, committing a transaction does not release any such locks obtained during
+ the transaction. It is also possible to recursively set the same lock. If a
+ lock with the same name is set n times, it needs to be released n times as well.
+ str is case insensitive for GET_LOCK() and related functions. If str is an empty
+ string or NULL, GET_LOCK() returns NULL and does nothing. timeout supports microseconds.
+ If the metadata_lock_info plugin is installed, locks acquired with this function
+ are visible in the Information Schema METADATA_LOCK_INFO table. This function
+ can be used to implement application locks or to simulate record locks. Names
+ are locked on a server-wide basis. If a name has been locked by one client,
+ GET_LOCK() blocks any request by another client for a lock with the same name.
+ This allows clients that agree on a given lock name to use the name to perform
+ cooperative advisory locking. But be aware that it also allows a client that
+ is not among the set of cooperating clients to lock a name, either inadvertently
+ or deliberately, and thus prevent any of the cooperating clients from locking
+ that name. One way to reduce the likelihood of this is to use lock names that
+ are database-specific or application-specific. For example, use lock names of
+ the form db_name.str or app_name.str. Statements using the GET_LOCK function
+ are not safe for statement-based replication. The patch to permit multiple locks
+ was contributed by Konstantin "Kostja" Osipov (MDEV-3917).

+ \ Passing NULL for the\ngtid-list makes the function return NULL immediately,\

+ \ application writes to a single master but divides the reads\nout to a number\
+ \ of slaves to distribute the load. In such a setup, there is a\nrisk that an\
+ \ application could first do an update on the master, and then a\nbit later\
+ \ do a read on a slave, and if the slave is not fast enough, the data\nread\
+ \ from the slave might not include the update just made, possibly confusing\n\
+ the application and/or the end-user. One way to avoid this is to request the\n\
+ value of last_gtid on the master just after the update. Then before doing the\n\
+ read on the slave, do a MASTER_GTID_WAIT() on the value obtained from the\n\
+ master; this will ensure that the read is not performed until the slave has\n\
+ replicated sufficiently far for the update to have become visible.\n\nNote that\
+ \ MASTER_GTID_WAIT() can be used even if the slave is configured not\nto use\
+ \ GTID for connections (CHANGE MASTER TO master_use_gtid=no). This is\nbecause\
+ \ from MariaDB 10, GTIDs are always logged on the master server, and\nalways\
+ \ recorded on the slave servers.\n\nDifferences to MASTER_POS_WAIT()\n--------------------------------\n\

+ \ area size (we'll discuss all of these shortly) as the transaction\njust terminated.\
+ \ The AND NO CHAIN option just tells your DBMS to end the\ntransaction - that\

+ description: 'ROWNUM() returns the current number of accepted rows in the current
+ context. It main purpose is to emulate the ROWNUM pseudo column in Oracle. For
+ MariaDB native applications, we recommend the usage of LIMIT, as it is easier
+ to use and gives more predictable results than the usage of ROWNUM(). The main
+ difference between using LIMIT and ROWNUM() to limit the rows in the result
+ is that LIMIT works on the result set while ROWNUM works on the number of accepted
+ rows (before any ORDER or GROUP BY clauses). The following queries will return
+ the same results: SELECT * from t1 LIMIT 10; SELECT * from t1 WHERE ROWNUM()
+ <= 10; While the following may return different results based on in which orders
+ the rows are found: SELECT * from t1 ORDER BY a LIMIT 10; SELECT * from t1 ORDER
+ BY a WHERE ROWNUM() <= 10; The recommended way to use ROWNUM to limit the number
+ of returned rows and get predictable results is to have the query in a subquery
+ and test for ROWNUM() in the outer query: SELECT * FROM (select * from t1 ORDER
+ BY a) WHERE ROWNUM() <= 10; ROWNUM() can be used in the following contexts:

+ summary: Returns a binary string representing the string's sorting and comparison
+ description: Returns a binary string representing the string's sorting and comparison
+ value. A string with a lower result means that for sorting purposes the string
+ appears before a string with a higher result. WEIGHT_STRING() is particularly
+ useful when adding new collations, for testing purposes. If str is a non-binary
+ string (CHAR, VARCHAR or TEXT), WEIGHT_STRING returns the string's collation
+ weight. If str is a binary string (BINARY, VARBINARY or BLOB), the return value
+ is simply the input value, since the weight for each byte in a binary string
+ is the byte value. WEIGHT_STRING() returns NULL if given a NULL input. The optional
+ AS clause permits casting the input string to a binary or non-binary string,
+ as well as to a particular length. AS BINARY(N) measures the length in bytes
+ rather than characters, and right pads with 0x00 bytes to the desired length.
+ AS CHAR(N) measures the length in characters, and right pads with spaces to
+ the desired length. N has a minimum value of 1, and if it is less than the length
+ of the input string, the string is truncated without warning. The optional LEVEL
+ clause specifies that the return value should contain weights for specific collation
+ levels. The levels specifier can either be a single integer, a comma-separated
+ list of integers, or a range of integers separated by a dash (whitespace is
+ ignored). Integers can range from 1 to a maximum of 6, dependent on the collation,
+ and need to be listed in ascending order. If the LEVEL clause is no provided,
+ a default of 1 to the maximum for the collation is assumed. If the LEVEL is
+ specified without using a range, an optional modifier is permitted. ASC, the
+ default, returns the weights without any modification. DESC returns bitwise-inverted
+ weights. REVERSE returns the weights in reverse order.

+ summary: AES_ENCRYPT() and AES_DECRYPT() implement encryption and decryption of
+ description: "AES_ENCRYPT() and AES_DECRYPT() implement encryption and decryption\
+ \ of\ndata using the official AES (Advanced Encryption Standard) algorithm,\n\
+ previously known as \"Rijndael.\" The AES standard permits various key\nlengths.\
+ \ By default these functions implement AES with a 128-bit key\nlength. Key lengths\
+ \ of 196 or 256 bits can be used, as described later.\nThe key length is a trade\
+ \ off between performance and security.\n\nAES_ENCRYPT() encrypts the string\
+ \ str using the key string key_str, and\nreturns a binary string containing\
+ \ the encrypted output. AES_DECRYPT()\ndecrypts the encrypted string crypt_str\
+ \ using the key string key_str,\nand returns the original (binary) string in\
+ \ hexadecimal format. (To\nobtain the string as plaintext, cast the result to\
+ \ CHAR. Alternatively,\nstart the mysql client with --skip-binary-as-hex to\
+ \ cause all binary\nvalues to be displayed as text.) If either function argument\
+ \ is NULL,\nthe function returns NULL. If AES_DECRYPT() detects invalid data\
+ \ or\nincorrect padding, it returns NULL. However, it is possible for\nAES_DECRYPT()\
+ \ to return a non-NULL value (possibly garbage) if the\ninput data or the key\
+ \ is invalid.\n\nThese functions support the use of a key derivation function\
+ \ (KDF) to\ncreate a cryptographically strong secret key from the information\n\
+ passed in key_str. The derived key is used to encrypt and decrypt the\ndata,\
+ \ and it remains in the MySQL Server instance and is not accessible\nto users.\
+ \ Using a KDF is highly recommended, as it provides better\nsecurity than specifying\
+ \ your own premade key or deriving it by a\nsimpler method as you use the function.\

+ \ enabled:\n\nmysql> SELECT name, address, MAX(age) FROM t GROUP BY name;\n\
+ ERROR 1055 (42000): Expression #2 of SELECT list is not in GROUP\nBY clause\

+ \nThe failure occurs because address is a nonaggregated column that is\nneither\
+ \ named among GROUP BY columns nor functionally dependent on\nthem. As a result,\
+ \ the address value for rows within each name group is\nnondeterministic. There\
+ \ are multiple ways to cause MySQL to accept the\nquery:\n\no Alter the table\

+ \ ANY_VALUE() is not an aggregate function,\n unlike functions such as SUM()\

+ It blocks until the replica has read and applied all updates up to the specified

+ events the replica had to wait for to advance to the specified position. The
+ function returns NULL if the replication SQL thread is not started, the replica''s
+ source information is not initialized, the arguments are incorrect, or an error
+ occurs. It returns -1 if the timeout has been exceeded. If the replication SQL
+ thread stops while SOURCE_POS_WAIT() is waiting, the function returns NULL.
+ If the replica is past the specified position, the function returns immediately.
+ If the binary log file position has been marked as invalid, the function waits
+ until a valid file position is known. The binary log file position can be marked
+ as invalid when the CHANGE REPLICATION SOURCE TO option GTID_ONLY is set for
+ the replication channel, and the server is restarted or replication is stopped.
+ The file position becomes valid after a transaction is successfully applied
+ past the given file position. If the applier does not reach the stated position,
+ the function waits until the timeout. Use a SHOW REPLICA STATUS statement to
+ check if the binary log file position has been marked as invalid. On a multithreaded

+ \ and str2 are considered equal)\n\no If WEIGHT_STRING(str1) < WEIGHT_STRING(str2),\
+ \ then str1 < str2 (str1\n sorts before str2)\n\nWEIGHT_STRING() is a debugging\
+ \ function intended for internal use. Its\nbehavior can change without notice\
+ \ between MySQL versions. It can be\nused for testing and debugging of collations,\
+ \ especially if you are\nadding a new collation. See\nhttps://dev.mysql.com/doc/refman/8.3/en/adding-collation.html.\n\

+ \ TEXT value,\nthe return value contains the collation weights for the string.\
+ \ If the\ninput is a binary (byte) string such as a BINARY, VARBINARY, or BLOB\n\
+ value, the return value is the same as the input (the weight for each\nbyte\
+ \ in a binary string is the byte value). If the input is NULL,\nWEIGHT_STRING()\

+- **Total tests:** 182 integration tests collected (266 with all engines)
+- **Passing:** 182 tests (+57 PostgreSQL) ✅ **100% PASS RATE**
+- **Skipped:** 0 tests ✅ **ALL TESTS ENABLED**

+ - SQLite: in-memory
+ - PostgreSQL: `latest`, `16`, `15` (3 versions)
+
+## 🏗️ Test Architecture
+
+Tests follow a **granular base class architecture** for maximum reusability and zero code duplication.
+
+### Directory Structure
+
+```
+tests/
+├── engines/
+│ ├── base_table_tests.py # Reusable table tests
+│ ├── base_record_tests.py # Reusable record tests
+│ ├── base_column_tests.py # Reusable column tests
+│ ├── base_index_tests.py # Reusable index tests
+│ ├── base_foreignkey_tests.py # Reusable foreign key tests
+│ ├── base_trigger_tests.py # Reusable trigger tests
+│ ├── base_view_tests.py # Reusable view tests

+│ └── {engine}/
+│ ├── conftest.py # Engine-specific fixtures
+│ ├── test_integration_suite.py # All integration tests
+│ └── test_ssh_tunnel.py # SSH tests (if supported)
+```
+
+### Design Principles
+
+1. **Base Classes** - Each database object has a dedicated base test class
+2. **Engine Inheritance** - Engine tests inherit from base classes
+3. **Fixture Injection** - Engine-specific behavior via pytest fixtures
+4. **Zero Duplication** - Test logic written once, runs on all engines
+5. **Granular Skipping** - Skip specific tests per engine when needed
+
+### Example: Column Tests
+
+**Base class** (`base_column_tests.py`):
+```python
+class BaseColumnTests:
+ def test_column_add(self, session, database, create_users_table, datatype_class):
+ # Generic test logic
+
+ @pytest.mark.skip_sqlite
+ def test_column_modify(self, session, database, create_users_table, datatype_class):
+ # Test that SQLite skips due to API incompatibility
+```
+
+**Engine implementation** (`mariadb/test_integration_suite.py`):
+```python
+@pytest.mark.integration
+class TestMariaDBColumn(BaseColumnTests):
+ pass # Inherits all tests, uses MariaDB fixtures
+```
+
+## 🚀 Running Tests
+
+### Run all integration tests
+```bash
+uv run pytest tests/engines/ -m integration
+```
+
+### Run specific engine
+```bash
+uv run pytest tests/engines/mariadb/ -m integration
+```
+
+### Run specific test class
+```bash
+uv run pytest tests/engines/mariadb/test_integration_suite.py::TestMariaDBColumn -m integration
+```
+
+### Run with coverage
+```bash
+uv run pytest tests/engines/ -m integration --cov=structures --cov-report=html
+```
+
+## 🐛 Known Issues
+
+### PostgreSQL Tests Skipped
+All PostgreSQL integration tests are currently skipped due to builder bugs:
+- `raw_create()` includes indexes in column list (SQL syntax error)
+- Index creation uses incorrect template
+- Needs separate fix before enabling tests
+
+### SQLite Column Operations
+SQLite has incompatible API for column modify/drop:
+- `modify()` - Returns `None`, uses drop+recreate pattern
+- `drop()` - Requires `(table, column)` parameters instead of `()`
+- Tests marked with `@pytest.mark.skip_sqlite`
+
+## 📝 Adding New Tests
+
+### 1. Create base test class
+```python
+# tests/engines/base_feature_tests.py
+class BaseFeatureTests:
+ def test_feature_operation(self, session, database, ...):
+ # Generic test logic
+```
+
+### 2. Update engine test suites
+```python
+# tests/engines/{engine}/test_integration_suite.py
+from tests.engines.base_feature_tests import BaseFeatureTests
+
+@pytest.mark.integration
+class Test{Engine}Feature(BaseFeatureTests):
+ pass
+```
+
+### 3. Add engine-specific fixtures if needed
+```python
+# tests/engines/{engine}/conftest.py
+@pytest.fixture
+def feature_specific_fixture():
+ return EngineSpecificValue
+```
+

+
+**Legend:**
+- ✅ **Implemented** - Method is correctly implemented
+- ⚠️ **Missing/Not Applicable** - Class or method not implemented for this engine
+- ❌ **Error** - Implementation exists but has bugs
+
+**Key Findings:**
+- ✅ **PostgreSQL 100% COMPLETE** - All 63 tests passing (was 0/63), full CRUD for all objects including Functions and Procedures
+- ✅ **Code style refactoring** - All `sql` variable names changed to `statement` across all engines
+- ✅ **PostgreSQL View implemented** - Uses `public` schema, proper `fully_qualified_name` override
+- ✅ **PostgreSQL Trigger implemented** - Uses regex to extract table name from CREATE TRIGGER statement for proper DROP
+- ✅ **PostgreSQL Column.modify implemented** - Uses separate ALTER COLUMN statements for type, nullable, default changes
+- ✅ **PostgreSQL Column added** - Missing `PostgreSQLColumn` class was the main cause of skipped tests
+- ✅ **PostgreSQL Check CRUD working** - All 9 Check tests now pass (was 0/9 before)
+- ✅ **PostgreSQL Table CRUD working** - All 9 Table tests now pass (create, drop, truncate, rename)
+- ✅ **PostgreSQL Record CRUD working** - All 9 Record tests now pass (insert, select, update, delete)
+- ✅ **PostgreSQL primary key detection fixed** - Uses `pg_index` instead of hardcoded 'PRIMARY' constraint name
+- ✅ **PostgreSQL Record uses DataTypeFormat** - Consistent with other engines, values formatted via `column.datatype.format()`
+- ✅ **Schema vs Database.name** - PostgreSQL correctly uses `schema` attribute with fallback to `database.name`
+- ✅ **Quoting refactored** - All engines now use `quote_identifier()` and `qualify()` instead of manual quoting
+- ✅ **`fully_qualified_name` property** - Centralized qualified name generation, PostgreSQL overrides for schema support
+- ✅ **Check constraints CRUD** - Full create/drop/alter support (MariaDB/MySQL/PostgreSQL/SQLite)
+- ✅ **Functions** - MariaDB/MySQL/PostgreSQL implemented
+ - MariaDB: ✅ `MariaDBFunction` with create/drop/alter
+ - MySQL: ✅ `MySQLFunction` with create/drop/alter
+ - PostgreSQL: ✅ **IMPLEMENTED** `PostgreSQLFunction` with create/drop/alter (plpgsql, volatility support)
+ - SQLite: ❌ N/A (SQLite doesn't support stored functions)
+- ⚠️ **Procedures** - PostgreSQL implemented, MariaDB/MySQL pending
+ - PostgreSQL: ✅ **IMPLEMENTED** `PostgreSQLProcedure` with create/drop/alter (plpgsql support)
+ - MariaDB/MySQL: ⚠️ NOT IMPLEMENTED (native support exists, classes missing)
+ - SQLite: ❌ N/A (SQLite doesn't support stored procedures)
+- ⚠️ **Events** - NOT IMPLEMENTED on any engine
+ - Abstract `SQLEvent` class exists but no engine implementation
+ - MariaDB/MySQL support events natively but classes missing
+ - PostgreSQL/SQLite: ❌ N/A (don't support scheduled events)
+- ⚠️ **SQLite Check/ForeignKey** - Inline-only (no separate create/drop after table creation)
+- ⚠️ **SQLite Column.modify** - Not supported (SQLite doesn't support ALTER COLUMN)
+- ⚠️ **MariaDB 5.5** - CHECK constraints not supported (too old, released 2009)
+
+## 📈 Test Quality Metrics
+
+- **Bug Detection** - Tests have found multiple API inconsistencies
+- **Regression Prevention** - Ensures changes don't break existing functionality
+- **Documentation** - Tests serve as executable API documentation
+- **Cross-Engine Validation** - Ensures consistent behavior across databases

+
+## 🚧 Missing Implementations
+
+### **PostgreSQL**
+- ✅ **DONE** `PostgreSQLFunction` - Implemented with create/drop/alter, plpgsql support
+- ✅ **DONE** `PostgreSQLProcedure` - Implemented with create/drop/alter, plpgsql support
+
+### **MariaDB/MySQL**

+# Autocomplete Testing
+
+This directory contains golden test cases for SQL autocomplete functionality.
+
+## Design Principles
+
+### Minimum Noise Principle
+**Suggest only what is truly useful.**
+
+The autocomplete system prioritizes relevance and context over completeness:
+- Without prefix: Show the most useful suggestions for the current context
+- With prefix: Filter all available options that match the prefix
+- Contextual keywords (e.g., `FROM users`) appear before plain keywords (e.g., `FROM`)
+- Plain keywords that guide workflow (e.g., `FROM`, `AS`) are shown even without context
+- Avoid redundant suggestions that add noise without value
+
+**Example:**
+```sql
+SELECT users.id |
+→ Suggestions: FROM users, AS, FROM
+ (Contextual keyword first, then plain keywords for flexibility)
+
+SELECT users.id F|
+→ Suggestions: FROM users, FROM
+ (Both match prefix "F")
+```
+
+## Test Structure
+
+Tests are organized in JSON files under `cases/` directory. Each file contains test cases for a specific autocomplete scenario.
+
+## Suggestion Ordering Rules
+
+The autocomplete system follows strict ordering rules to ensure predictable and useful suggestions:
+
+### 1. Columns
+**Ordered by schema definition** (as they appear in the table structure), NOT alphabetically.
+
+Example: For table `users(id, name, email, status, created_at)`, suggestions appear in that exact order.
+
+### 2. Tables
+**Ordered alphabetically** by table name.
+
+Special cases:
+- **CTEs (Common Table Expressions)**: Appear first
+- **Referenced tables**: Tables used in CTEs or SELECT appear before unreferenced tables
+- **Other tables**: Alphabetically sorted
+
+### 3. Functions and Keywords
+**Ordered alphabetically** by name.
+
+### 4. Literals
+Constants like `NULL`, `TRUE`, `FALSE` appear after columns but before functions.
+
+## Example
+
+For `SELECT * FROM users u JOIN orders o ON |`:
+
+```
+Suggestions order:
+1. o.id, o.user_id, o.total, o.status, o.created_at (JOIN table 'orders' columns by schema)
+2. u.id, u.name, u.email, u.status, u.created_at (FROM table 'users' columns by schema)
+3. NULL, TRUE, FALSE (literals)
+4. AVG, COALESCE, CONCAT, COUNT, ... (functions alphabetically)
+```
+
+Note: In JOIN ON context, JOIN tables appear before FROM tables. Columns within each table follow schema order.
+
+### JOIN ON Column Filtering Rule
+
+After an operator in JOIN ON clause, only columns from OTHER tables are suggested:
+
+- `FROM users u JOIN orders o ON u.id = |` → Suggest ONLY `o.*` columns (not `u.*`)
+- `FROM users u JOIN orders o ON o.user_id = |` → Suggest ONLY `u.*` columns (not `o.*`)
+
+The query can be written both ways:
+- `users.id = orders.user_id` ✓
+- `orders.user_id = users.id` ✓
+
+The system detects which table is on the left of the operator and filters out ALL columns from that table.
+
+## Test Coverage Matrix

+## Implementation Notes
+
+- `DERIVED_TABLES_CTE` is fully enabled in the current suite with lightweight virtual-table scope resolution.
+- Current implementation intentionally targets common patterns (`WITH ... AS (SELECT col1, col2 ...)`, `FROM (SELECT col1, col2 ...) AS alias`) and avoids deep SQL normalization.
+- If we later need nested or highly dynamic CTE projection inference, we can extend parsing incrementally without changing the test contract.

+# SQL Autocomplete Rules
+
+This document defines the autocomplete behavior for each SQL context.
+
+---
+
+## Glossary
+
+This section defines key terms used throughout the document to avoid ambiguity.
+
+### Statement vs Query vs Buffer
+
+- **Buffer**: The entire text content in the SQL editor, potentially containing multiple queries
+- **Statement**: A single SQL query separated by the effective statement separator (e.g., `;` or `GO`)
+- **Query**: Synonym for statement - a single executable SQL command
+- **Current statement**: The statement where the cursor is currently positioned
+
+**Example:**
+```sql
+SELECT * FROM users; -- Statement 1
+SELECT * FROM orders; -- Statement 2 (current statement if cursor is here)
+SELECT * FROM products; -- Statement 3
+```
+
+### Scope and Tables
+
+- **Scope tables**: Tables/CTEs/derived tables that appear in the current statement's FROM/JOIN clauses
+ - Includes: physical tables, CTEs (Common Table Expressions), derived tables (subquery aliases)
+ - Priority order: derived tables > CTEs > physical tables (see **Tables in Scope Definition** section)
+- **In scope**: A table is "in scope" if it appears in the FROM/JOIN of the current statement
+- **Out of scope**: A table exists in the database but is not referenced in the current statement's FROM/JOIN
+- **DB-wide tables**: All physical tables in the database, regardless of scope
+- **CURRENT_TABLE**: The table currently selected in the table editor UI (optional, may be `None`)
+
+### Scope Classification
+
+The scope classification determines which columns are suggested in expression contexts:
+
+- **SCOPED**: Explicit scope exists via FROM/JOIN clauses in the current statement
+ - Example: `SELECT id, | FROM users` → scope = `users` table
+ - Example: `SELECT * FROM users u JOIN orders o ON u.id = o.user_id; SELECT u.id, |` → scope = `u`, `o` tables
+ - Behavior: Suggest only columns from scope tables (qualified if multiple tables, unqualified if single table)
+
+- **VIRTUAL_SCOPED**: Implicit scope inferred from context without explicit FROM/JOIN
+ - Via qualified columns: `SELECT users.id, |` → virtual scope = `users` (inferred from qualified column)
+ - Via CURRENT_TABLE: `SELECT id, |` with CURRENT_TABLE=users → virtual scope = `users`
+ - **CRITICAL:** VIRTUAL_SCOPED requires CURRENT_TABLE to be set in UI (or qualified column present)
+ - When VIRTUAL_SCOPED via CURRENT_TABLE (no FROM/JOIN), columns MUST be qualified (e.g., `users.id`, not `id`)
+ - Behavior: Suggest columns from the inferred table(s), but allow DB-wide suggestions with prefix
+
+- **NO_SCOPED**: No scope information available
+ - No FROM/JOIN in current statement
+ - No qualified columns to infer scope from
+ - No CURRENT_TABLE set
+ - Example: `SELECT id, |` with CURRENT_TABLE=null and no qualified columns
+ - Behavior: Suggest only functions (no columns without prefix)
+
+### Prefix and Token
+
+- **Token**: A valid SQL identifier matching `^[A-Za-z_][A-Za-z0-9_]*$` (or dialect-equivalent)
+ - Must start with letter or underscore (NOT digit)
+ - Can contain letters, digits, underscores after first character
+ - Dialect-aware: some dialects support `$`, `#`, or unicode in identifiers
+- **Prefix**: The token immediately before the cursor, without containing `.`
+- **Dot-completion**: When the token before cursor contains `.` (e.g., `users.` or `u.`)
+
+**Examples:**
+- `SELECT u|` → prefix = `"u"`, triggers prefix matching
+- `SELECT u.i|` → NOT a prefix (contains dot), triggers dot-completion on `u`
+- `SELECT ui|` → prefix = `"ui"`, triggers prefix matching
+- `SELECT 1|` → NOT a token (starts with digit), no prefix matching
+
+### Context Types
+
+- **Table-selection context**: Context where tables are suggested (FROM_CLAUSE, JOIN_CLAUSE)
+- **Expression context**: Context where columns/functions are suggested (SELECT_LIST, WHERE, JOIN_ON, ORDER_BY, GROUP_BY, HAVING)
+- **Scope-restricted expression context**: Expression context that MUST limit suggestions to scope tables only (WHERE, JOIN_ON, ORDER_BY, GROUP_BY, HAVING)
+
+### Qualification
+
+- **Qualified column**: Column name prefixed with table/alias (e.g., `users.id` or `u.id`)
+- **Unqualified column**: Column name without prefix (e.g., `id`)
+- **Alias-first qualification**: Use `alias.column` when alias exists, otherwise `table.column`
+
+---
+
+## Important Note on Column Ordering in Examples
+
+**All column suggestions throughout this document preserve their table definition order (schema order / ordinal_position), NOT alphabetical order.**
+
+Examples may show columns in sequences that appear alphabetical for readability, but the implementation MUST return columns in their actual schema order. When in doubt, the rule is: **preserve schema order, NOT alphabetical order**.
+
+For clarity, examples use the following assumed schema order:
+- `users`: id, name, email, password, is_enabled, created_at
+- `orders`: id, user_id, total, created_at
+- `products`: id, name, unit_price, stock
+
+---
+
+## Context Detection
+
+The autocomplete system uses `sqlglot` to parse the SQL query and determine the current context.
+Contexts are defined in the `SQLContext` enum.
+
+---
+
+## Key Examples: Scope Restriction in Action
+
+These examples demonstrate the strict separation between table-selection and expression contexts.
+
+**Assume:** `CURRENT_TABLE = users` (set in table editor)
+
+### Example 1: SELECT with no FROM → CURRENT_TABLE + DB-wide allowed
+
+```sql
+SELECT u|
+```
+
+**Context:** SELECT_LIST, no scope tables exist
+
+**Suggestions:**
+- `users.id, users.name, users.email, ...` (CURRENT_TABLE columns first)
+- `products.unit_price, ...` (DB-wide columns matching 'u')
+- `UPPER, UUID, UNIX_TIMESTAMP` (functions)
+
+**Rationale:** No scope tables exist, so CURRENT_TABLE and DB-wide columns are allowed.
+
+---
+
+### Example 2: FROM/JOIN suggests CURRENT_TABLE as table candidate
+
+```sql
+SELECT * FROM orders JOIN |
+```
+
+**Context:** JOIN_CLAUSE (table-selection)
+
+**Suggestions:**
+- `users` (CURRENT_TABLE as convenience shortcut)
+- `products, customers, ...` (other physical tables)
+- CTEs (if any)
+
+**Rationale:** JOIN_CLAUSE is table-selection. CURRENT_TABLE may be suggested even though scope tables (orders) already exist. This is how the user brings it into scope.
+
+---
+
+### Example 3: WHERE/JOIN_ON shows only scoped columns (CURRENT_TABLE excluded unless in scope)
+
+```sql
+-- Case A: CURRENT_TABLE not in scope
+SELECT * FROM orders WHERE u|
+```
+
+**Context:** WHERE (expression context), scope = [orders]
+
+**Suggestions:**
+- `orders.user_id` (scope table column matching 'u')
+- `UPPER, UUID, UNIX_TIMESTAMP` (functions)
+
+**NOT suggested:**
+- ❌ `users.*` (CURRENT_TABLE not in scope)
+- ❌ `products.unit_price` (DB-wide column)
+
+**Rationale:** WHERE is an expression context with scope tables. CURRENT_TABLE is not in scope, so it MUST be ignored. DB-wide columns MUST NOT be suggested.
+
+```sql
+-- Case B: CURRENT_TABLE in scope
+SELECT * FROM users u JOIN orders o WHERE u|
+```
+
+**Context:** WHERE (expression context), scope = [users (alias u), orders (alias o)]
+
+**Suggestions:**
+- `u.id, u.name, u.email, u.password, u.is_enabled, u.created_at` (CURRENT_TABLE in scope via alias 'u', schema order)
+- `UPPER, UUID, UNIX_TIMESTAMP` (functions)
+
+**Rationale:** CURRENT_TABLE (users) is in scope via alias 'u', so its columns are included.
+
+---
+
+## Precedence Chain
+
+The autocomplete resolution follows this strict precedence order:
+
+1. **Multi-Query Separation**
+ - If multiple queries in editor (separated by the effective statement separator), extract the current statement where the cursor is
+ - All subsequent rules apply only to current statement
+
+2. **Dot-Completion** (`table.` or `alias.`)
+ - If token immediately before cursor contains `.` → Dot-Completion mode
+ - Show columns of that table/alias (ignore broader context)
+ - Example: `WHERE u.i|` → show columns of `u` starting with `i`
+
+3. **Context Detection** (sqlglot/regex)
+ - Determine SQL context: SELECT_LIST, WHERE, JOIN ON, ORDER BY, etc.
+ - Use sqlglot parsing (primary) or regex fallback
+
+4. **Within Context: Prefix Rules**
+ - If prefix exists (token before cursor without `.`) → apply prefix matching
+ - Check for exact alias match first (Alias Prefix Disambiguation)
+ - Otherwise generic prefix matching (tables, columns, functions, keywords)
+
+**Example resolution:**
+```sql
+-- Multi-query: extract current statement
+SELECT * FROM users; SELECT * FROM orders WHERE u|
+
+-- No dot → not Dot-Completion
+-- Context: WHERE clause (scope-restricted expression context)
+-- Scope: orders (from current statement's FROM clause)
+-- Prefix: "u"
+-- Check aliases: no alias "u" in this statement
+-- Generic prefix (scope-restricted): show orders.user_id, UPPER, UUID, etc.
+-- DB-wide columns excluded (scope restriction active)
+```
+
+**Example with dot:**
+```sql
+SELECT * FROM users u WHERE u.i|
+
+-- Dot detected → Dot-Completion (precedence 2)
+-- Show columns of "u" starting with "i"
+-- Context (WHERE) is ignored for this specific resolution
+```
+
+This precedence eliminates ambiguity: **Dot-Completion always wins**, then context, then prefix rules.
+
+---
+
+## Universal Rules (Apply to All Contexts)
+
+### Prefix Definition
+
+**Prefix** = the identifier token immediately before the cursor, matching `^[A-Za-z_][A-Za-z0-9_]*$` (or equivalent for dialect).
+
+**Rules:**
+- Must start with letter or underscore (NOT digit)
+- Can contain letters, digits, underscores after first character
+- Match is case-insensitive
+- Output preserves original form (alias/table/column name)
+- If token contains `.` → **not a prefix**: triggers Dot-Completion instead
+
+**Cursor Position Handling:**
+- **Cursor at end of token** (e.g., `SELECT u|`): prefix = entire token before cursor
+- **Cursor in middle of token** (e.g., `SEL|ECT`, `users.na|me`): prefix = partial token before cursor
+ - Text after cursor is ignored for matching
+ - Selecting a suggestion replaces the entire token (not just the part before cursor)
+
+**Examples:**
+```sql
+SELECT u|
+→ Prefix: "u" (triggers prefix matching)
+
+SELECT u.i|
+→ NOT a prefix (contains dot)
+→ Triggers Dot-Completion on table/alias "u"
+
+SEL|ECT
+→ Prefix: "SEL" (cursor in middle of token)
+→ Suggestions: SELECT
+→ Selection replaces entire token "SELECT" (removes "ECT")
+
+users.na|me
+→ Dot-completion on "users"
+→ Prefix: "na" (cursor in middle of token)
+→ Suggestions: name
+→ Selection replaces entire token "name" (removes "me")
+
+SELECT ui|
+→ Prefix: "ui" (triggers prefix matching)
+```
+
+**This distinction is critical:**
+- `u.i|` → Dot-Completion (show columns of table/alias `u` starting with `i`)
+- `ui|` → Prefix matching (show items starting with `ui`)
+
+---
+
+### Column Qualification (table.column vs alias.column)
+
+**Qualification rules:**
+
+1. **Single table in scope (no ambiguity):**
+ - **No prefix:** Use **unqualified** column names (e.g., `id`, `name`)
+ - **With prefix:**
+ - **Column-name match** (Generic Prefix Matching rule B): Use **unqualified** column names (e.g., `name`)
+ - **Table-name expansion** (Generic Prefix Matching rule A): Use **qualified** column names (e.g., `users.id`)
+ - **Order when BOTH match:**
+ 1. Column-name matches **unqualified** (e.g., `id`, `item_name`)
+ 2. Column-name matches **qualified** (e.g., `items.id`, `items.item_name`)
+ 3. Table-name expansion remaining columns **qualified** (e.g., `items.*` excluding already shown columns)
+ 4. Functions
+2. **Multiple tables in scope:** Use qualified names with alias-first preference:
+ - If alias exists: `alias.column` (e.g., `u.id`)
+ - If no alias: `table.column` (e.g., `users.id`)
+
+3. **CRITICAL - Aliased tables:** When a table has an alias, the original table name CANNOT be used for qualification. SQL will reject `table.column` when an alias exists.
+ - **Correct:** `FROM users u WHERE u.id = 1` (use alias)
+ - **INCORRECT:** `FROM users u WHERE users.id = 1` (SQL error - table name not accessible)
+ - **Implication for autocomplete:** If prefix does not match the alias and does not match any column name, return empty suggestions. Do NOT suggest qualified columns with the original table name.
+ - **Example:** `FROM users u WHERE us|` → NO suggestions (prefix 'us' does not match alias 'u' or any column)
+
+4. **Consistency rule - Qualified context propagation:** If the query already uses at least one qualified column (e.g., `users.id` or `u.id`) in the SELECT list, column suggestions MUST stay qualified for consistency, even for single-table scopes.
+ - This is a style lock: once qualified style is used, autocomplete keeps qualified style.
+ - Applies to all column contexts: SELECT list (after comma), WHERE, JOIN ON, ORDER BY, GROUP BY, HAVING.
+ - For aliased tables, qualification MUST use alias only (never table name).
+ - For non-aliased tables, qualification uses `table.column`.
+
+**Rationale:** When only one table is in scope, qualification usually adds noise. However, table-name prefix expansion and explicit qualified usage both express a clear qualification intent. Once user intent is qualified style, maintaining it across contexts keeps SQL consistent and avoids invalid `table.column` usage when aliases are present.
+
+**Examples:**
+```sql
+-- Single table, no prefix: unqualified
+SELECT * FROM users WHERE |
+→ id, name, email, password, is_enabled, created_at
+
+-- Single table, prefix matches ONLY column name: unqualified
+SELECT * FROM users WHERE n|
+→ name (column-name match, unqualified)
+→ (functions starting with 'n' if any)
+
+-- Single table, prefix matches ONLY table name: qualified (table-name expansion)
+SELECT * FROM users WHERE u|
+→ users.id, users.name, users.email, users.password, users.is_enabled, users.created_at (table-name expansion, qualified)
+→ UPPER, UUID, UNIX_TIMESTAMP (functions)
+
+-- Single table, prefix matches BOTH column name AND table name: both shown
+-- Example: table 'items' with columns: id, item_name, stock, price
+SELECT * FROM items WHERE i|
+→ id, item_name (column-name match, unqualified - FIRST)
+→ items.id, items.item_name (column-name match, qualified - SECOND)
+→ items.stock, items.price (table-name expansion remaining, qualified - THIRD)
+→ IF, IFNULL (functions - FOURTH)
+
+-- Single table with alias, no qualified style yet: unqualified
+SELECT * FROM users u WHERE |
+→ id, name, email
+
+-- Multiple tables: qualified (alias-first)
+SELECT * FROM users u JOIN orders o ON u.id = o.user_id WHERE |
+→ u.id, u.name, u.email, o.user_id, o.total, o.created_at
+
+-- Consistency rule: qualified style propagates to all contexts
+SELECT u.id FROM users u WHERE |
+→ u.id, u.name, u.email, u.status, u.created_at
+
+SELECT u.id FROM users u ORDER BY |
+→ u.id, u.name, u.email, ...
+
+SELECT u.id, COUNT(*) FROM users u GROUP BY |
+→ u.id, u.name, u.email, ...
+```
+
+**Note:** This rule applies to all contexts: SELECT_LIST, WHERE, JOIN ON, ORDER BY, GROUP BY, HAVING.
+
+**Exception:** Dot-completion mode always returns **unqualified** column names (e.g., `id`, `name`), regardless of scope table count. See **Dot-Completion** section for details.
+
+---
+
+### Comma and Whitespace Behavior
+
+**Universal rule for all contexts:**
+
+- **Comma is never suggested** as an autocomplete item
+- If the user types `,` → they want another item → apply "next-item" rules for that context (e.g., after comma in SELECT list, show columns/functions)
+- If the user types **whitespace** after a completed identifier/expression → treat it as "selection complete" → show only keywords valid in that position (clause keywords or context modifiers like `ASC`, `DESC`, `NULLS FIRST`, etc.)
+- **Exception:** If whitespace follows an incomplete/invalid keyword (e.g., `SEL |` where `SEL` is not a recognized keyword) → show nothing (no suggestions)
+
+**Rationale:** Whitespace signals intentional pause/completion. Comma signals continuation. Incomplete keywords with whitespace are ambiguous and should not trigger suggestions. This distinction applies consistently across all SQL contexts.
+
+**Examples:**
+```sql
+SELECT id, |
+→ Comma typed → next-item rules → show columns/functions
+
+SELECT id |
+→ Whitespace typed → selection complete → show clause keywords (FROM, WHERE, AS, ...)
+
+ORDER BY created_at, |
+→ Comma typed → next-item rules → show columns/functions
+
+ORDER BY created_at |
+→ Whitespace typed → selection complete → show ASC, DESC, NULLS FIRST, NULLS LAST
+```
+
+**Special case - Qualified column in SELECT_LIST:**
+```sql
+SELECT users.id |
+→ Whitespace after qualified column → suggest contextual keywords + plain keywords
+→ Suggestions: FROM users, AS, FROM
+
+SELECT users.id F|
+→ Whitespace after qualified column + prefix 'F'
+→ Suggest: FROM {table} (contextual keyword) + FROM (plain keyword)
+→ Suggestions: FROM users, FROM
+
+SELECT users.id W|
+→ Whitespace after qualified column + prefix 'W'
+→ WHERE is syntactically invalid (cannot follow SELECT item directly)
+→ Suggestions: [] (empty - no valid suggestions)
+```
+
+**Terminology:**
+- **Contextual keyword**: A keyword enriched with context-specific information (e.g., `FROM users` where `users` is inferred from the qualified column)
+- **Plain keyword**: Generic keyword without context (e.g., `FROM`, `AS`)
+
+**Ordering:** Contextual keywords MUST appear before plain keywords.
+
+**Rationale:** When a qualified column is used (e.g., `users.id`), the table name is already known. Suggesting `FROM {table}` as a contextual keyword helps the user quickly add the FROM clause with the correct table. However, `FROM` plain keyword is also shown because the user might want to use a different table (e.g., `FROM orders AS users`). Contextual keywords are more specific and useful than plain keywords, so they appear first. With prefix, filter contextual keywords + plain keywords by prefix. Some keywords (e.g., WHERE) are syntactically invalid after SELECT item and should not be suggested.
+
+---
+
+### Scope-Restricted Expression Contexts
+
+**Definition:** The following contexts are **scope-restricted expression contexts**:
+- WHERE
+- JOIN_ON
+- ORDER_BY
+- GROUP_BY
+- HAVING
+
+**Scope restriction rules for these contexts:**
+- Column suggestions MUST be limited to scope tables only
+- Database-wide columns MUST NOT be suggested
+- Table-name expansion MUST be limited to scope tables only
+- Column-name matching MUST be limited to scope tables only
+- `CURRENT_TABLE` columns MUST NOT be suggested unless `CURRENT_TABLE` is in scope
+
+**Operator context rule (WHERE, JOIN_ON):**
+- When cursor is after a comparison operator (`=`, `!=`, `<>`, `<`, `>`, `<=`, `>=`, `LIKE`, `IN`, etc.)
+- The column **immediately to the LEFT** of the current operator MUST NOT be suggested
+- **Rationale:** Suggesting the same column on both sides (e.g., `WHERE users.id = users.id`) is redundant and not useful
+
+**Definition of "column immediately to the LEFT":**
+- Parse the expression immediately to the left of the operator using AST
+- If the expression root is (or contains as root) a **column reference** (qualified or unqualified):
+ - Exclude that column from suggestions
+- If the expression root is a **function call, cast, or literal**:
+ - Do NOT exclude any columns (even if the function contains columns as arguments)
+
+**Examples:**
+```sql
+WHERE users.id = |
+→ Exclude: users.id (direct column reference)
+
+WHERE (users.id) = |
+→ Exclude: users.id (parentheses ignored, root = column reference)
+
+WHERE users.id::int = |
+→ Exclude: users.id (cast ignored, root = column reference)
+
+WHERE COALESCE(users.id, 0) = |
+→ Do NOT exclude users.id (root = function call, not column reference)
+
+WHERE users.id + 1 = |
+→ Exclude: users.id (binary expression, root contains column reference)
+
+WHERE users.id = orders.user_id AND status = |
+→ Exclude only: status (immediately left of current operator)
+→ Do NOT exclude: users.id, orders.user_id (not immediately left)
+```
+
+**Rationale:** These clauses cannot legally reference tables not present in scope.
+
+---
+
+### CURRENT_TABLE Scope Restriction
+
+**Definition:** `CURRENT_TABLE` = UI-selected table from table editor context (optional, may be `None`).
+
+**Scope tables** = tables/CTEs/derived tables that appear in the current statement's FROM/JOIN clauses:
+- Physical tables in FROM/JOIN
+- CTEs referenced in FROM/JOIN
+- Derived tables (subquery aliases) in FROM/JOIN
+
+---
+
+#### Table-Selection Contexts (FROM_CLAUSE, JOIN_CLAUSE)
+
+These contexts suggest **tables**, not columns.
+
+**Rules:**
+- `CURRENT_TABLE` MAY be suggested as a table candidate
+- Allowed even if scope tables already exist (this is how user brings it into scope)
+- MUST NOT suggest `CURRENT_TABLE` if it is already present in the current statement
+- **Statement definition:** The current query where the cursor is located, separated by the effective statement separator (not the entire buffer)
+- Purpose: convenience shortcut for selecting the current table
+
+**Example:**
+```sql
+SELECT * FROM users; SELECT * FROM |
+```
+In this case, `users` is NOT present in the current statement (second query), so it MAY be suggested if it is `CURRENT_TABLE`.
+
+---
+
+#### Expression Contexts (JOIN_ON, WHERE, ORDER_BY, GROUP_BY, HAVING)
+
+These are **scope-restricted expression contexts** (see **Scope-Restricted Expression Contexts** section).
+
+These contexts suggest **columns** from scope tables only.
+
+---
+
+#### SELECT_LIST Context (Special Case)
+
+**If statement has NO scope tables (no FROM/JOIN yet):**
+- Without prefix: `CURRENT_TABLE` columns MUST be included first (if set)
+- With prefix: `CURRENT_TABLE` columns MUST be included ONLY if they match the prefix via:
+ - Column-name match (e.g., `SELECT na|` → `name` from CURRENT_TABLE)
+ - Table-name expansion (e.g., `SELECT u|` and CURRENT_TABLE is `users` → suggest `users.*` columns)
+- Database-wide columns MUST be included ONLY if prefix exists (guardrail: avoid noise when no prefix)
+- Functions and keywords are included
+
+**If statement HAS scope tables (FROM/JOIN exists):**
+- `CURRENT_TABLE` columns MUST be included ONLY if `CURRENT_TABLE` is in scope
+- If `CURRENT_TABLE` is not in scope, it MUST be ignored
+- Database-wide columns MUST NOT be suggested
+- Scope table columns are included with alias-first qualification
+- **Exception:** If prefix matches DB-wide tables but no scope tables/columns, suggest Out-of-Scope Table Hints (see dedicated section)
+
+---
+
+### Dot-Completion (table.column or alias.column)
+
+**Trigger:** After `table.` or `alias.` in any SQL context
+
+**Show:**
+- Columns of the specific table/alias (filtered by prefix if present)
+
+**Scope lookup:**
+- Dot-completion works for physical tables, aliases, derived tables (subquery aliases), and CTEs
+- The table/alias is resolved from the current statement's scope (FROM/JOIN clauses)
+- For derived tables and CTEs, columns are shown if their column list is known/parseable
+- If table/alias not found in scope, return empty suggestions (see Edge Case #8)
+
+**Output format:** Unqualified column names (e.g., `id`, `name`) NOT qualified (e.g., `u.id`, `u.name`). This is an exception to the alias-first rule used elsewhere.
+
+**Ordering:** Dot-completion bypasses global ordering rules and returns only the selected table's columns (table definition order). Columns preserve their ordinal position in the table schema. No functions, keywords, or other tables.
+
+**Filtering:** When a prefix is present after the dot (e.g., `users.i|`), filtering uses `startswith(prefix)` on column name (case-insensitive). NOT contains or fuzzy matching.
+
+**Examples:**
+```sql
+SELECT users.|
+→ id, name, email, password, is_enabled, created_at (schema order, NOT alphabetical)
+→ NOT users.id, users.name, ...
+
+SELECT users.i|
+→ id, is_enabled (columns starting with 'i', in schema order)
+→ NOT users.id
+
+WHERE u.| (where u is alias of users)
+→ id, name, email, password, is_enabled, created_at (schema order)
+→ NOT u.id, u.name, ...
+
+ON orders.|
+→ id, user_id, total, created_at
+
+ORDER BY users.|
+→ id, name, email, password, is_enabled, created_at (schema order)
+
+-- Dot-completion on CTE alias
+WITH active_users AS (SELECT id, name FROM users WHERE status = 'active')
+SELECT au.| FROM active_users au
+→ id, name (CTE columns, schema order)
+
+-- Dot-completion on derived table alias
+SELECT dt.| FROM (SELECT id, total FROM orders) AS dt
+→ id, total (derived table columns, schema order)
+```
+
+**Note:** This rule takes precedence over context-specific rules when a dot is detected.
+
+---
+
+## Autocomplete Rules by Context
+
+### 1. EMPTY (Empty editor)
+
+**Trigger:** Completely empty editor (no characters typed)
+
+**Show:**
+- Primary keywords: `SELECT`, `INSERT`, `UPDATE`, `DELETE`, `CREATE`, `DROP`, `ALTER`, `TRUNCATE`, `SHOW`, `DESCRIBE`, `EXPLAIN`, `WITH`, `REPLACE`, `MERGE`
+
+**Examples:**
+```sql
+| → SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ...
+```
+
+---
+
+### 2. SINGLE_TOKEN (Single token without spaces)
+
+**Trigger:** Single partial token, no spaces
+
+**Important:** Applies only if the entire current statement contains exactly one token (no whitespace). Whitespace includes newline. This avoids misinterpretation when splitting statements/lines.
+
+**Token definition:** A valid identifier matching the pattern `^[A-Za-z_][A-Za-z0-9_]*$` (or dialect-equivalent). This excludes symbols like `(`, `)`, `,`, `.`, etc. Examples: `SEL` ✅, `SEL(` ❌, `SELECT,` ❌.
+
+**Distinction from EMPTY:**
+- EMPTY: No characters typed (cursor at position 0)
+- SINGLE_TOKEN: At least one character typed, no whitespace
+
+**Note:** Token matching is dialect-aware; the pattern above is the default baseline. Some dialects may support `$`, `#`, or unicode characters in identifiers.
+
+**Show:**
+- All keywords (filtered by prefix)
+
+**Examples:**
+```sql
+S| → SELECT, SHOW, SET (SINGLE_TOKEN - one character typed)
+SEL| → SELECT (SINGLE_TOKEN)
+| → SELECT, INSERT, UPDATE (EMPTY - no characters)
+```
+
+---
+
+### 3. SELECT_LIST (Inside SELECT, before FROM)
+
+**Trigger:** After `SELECT` and before `FROM`
+
+**Important:** Column suggestions depend on whether FROM/JOIN are present in the query.
+
+#### 3a. Without prefix (after SELECT, no FROM/JOIN in query)
+
+**Show:**
+- `CURRENT_TABLE` columns (if set)
+- Functions
+- Keywords (FROM, WHERE, etc.) - **only if SELECT list already has items**
+ - e.g., `SELECT id |` → show keywords (can continue query)
+ - e.g., `SELECT |` → no keywords (nothing to continue)
+
+**Rationale:** Keywords like FROM/WHERE make sense to continue the query, but only if there's already something to continue from. Empty SELECT has no context for keywords.
+
+**Examples:**
+```sql
+-- Assume CURRENT_TABLE = users
+SELECT |
+→ users.id, users.name, users.email, users.status, users.created_at
+→ COUNT, SUM, AVG, MAX, MIN, UPPER, LOWER, ...
+
+-- SELECT with existing item + CURRENT_TABLE
+SELECT id |
+→ users.id, users.name, users.email, users.status, users.created_at
+→ FROM, WHERE, LIMIT, ...
+
+-- No CURRENT_TABLE set (empty SELECT)
+SELECT |
+→ COUNT, SUM, AVG, MAX, MIN, UPPER, LOWER, ...
+```
+
+#### 3a-bis. Without prefix (after SELECT, with FROM/JOIN in query)
+
+**Show:**
+- Columns in scope (unqualified if single table, qualified with alias-first if multiple tables)
+ - **Note:** With prefix, see **Generic Prefix Matching** section for table-name expansion rules
+- All functions
+
+**Examples:**
+```sql
+SELECT * FROM users WHERE id = 1; SELECT |
+→ id, name, email, password, is_enabled, created_at, ... (single table: unqualified)
+→ COUNT, SUM, AVG, ...
+
+SELECT * FROM users u JOIN orders o ON u.id = o.user_id; SELECT |
+→ u.id, u.name, o.user_id, o.total, ... (multiple tables: qualified)
+→ COUNT, SUM, AVG, ...
+```
+
+#### 3b. With prefix
+
+**Show:**
+- Columns matching the prefix (see **Generic Prefix Matching for Column Contexts** section)
+- Functions matching the prefix
+- **Note:** Keywords are NOT included (syntactically invalid in SELECT list, e.g., `SELECT SELECT` or `SELECT UPDATE`)
+
+**Matching priority:**
+1. If prefix exactly equals an alias → Alias-exact-match mode (see **Alias Prefix Disambiguation** section)
+2. Otherwise → Generic prefix matching (see **Generic Prefix Matching for Column Contexts** section)
+
+**CURRENT_TABLE handling:**
+
+- **When NO scope tables exist (no FROM/JOIN):**
+ - `CURRENT_TABLE` columns MUST be included first (if set)
+ - Database-wide table-name expansion and column-name matching are included
+ - Functions are included
+
+- **When NO scope tables AND NO prefix:**
+ - `CURRENT_TABLE` columns (if set)
+ - Functions
+ - Keywords - only if SELECT list already has items (e.g., `SELECT id |`)
+ - **Rationale:** Keywords only make sense when there's something to continue from
+
+- **When scope tables exist (FROM/JOIN present):**
+ - `CURRENT_TABLE` columns MUST be included ONLY if `CURRENT_TABLE` is in scope
+ - If `CURRENT_TABLE` is not in scope, it MUST be ignored
+ - Scope table columns are included with alias-first qualification
+ - **Out-of-Scope Table Hints:** If prefix matches DB-wide tables but no scope tables/columns, suggest table names as hints (see **Out-of-Scope Table Hints** section)
+
+**Examples:**
+
+**No FROM/JOIN (CURRENT_TABLE included):**
+```sql
+-- Assume CURRENT_TABLE = users
+SELECT u|
+→ users.id, users.name, users.email, ... (CURRENT_TABLE via table-name expansion)
+→ user_sessions.* (other tables starting with 'u')
+→ orders.user_id, products.unit_price (DB-wide columns starting with 'u')
+→ Functions: UPPER, UUID, UNIX_TIMESTAMP
+```
+
+**FROM/JOIN exists, CURRENT_TABLE not in scope (CURRENT_TABLE ignored):**
+```sql
+-- Assume CURRENT_TABLE = users
+SELECT u| FROM orders
+→ orders.user_id (scope table column starting with 'u')
+→ UPPER, UUID, UNIX_TIMESTAMP (functions)
+→ users + Add via FROM/JOIN (Out-of-Scope Table Hint)
+→ (CURRENT_TABLE ignored - not in scope)
+→ (DB-wide columns excluded - scope restriction active)
+```
+
+**FROM/JOIN exists, CURRENT_TABLE in scope (CURRENT_TABLE included):**
+```sql
+-- Assume CURRENT_TABLE = users
+SELECT u| FROM users u JOIN orders o
+→ Alias-exact-match mode activated (u == alias 'u')
+→ u.id, u.name, u.email (CURRENT_TABLE in scope via alias 'u')
+→ UPPER, UUID, UNIX_TIMESTAMP (functions)
+```
+
+#### 3c. After comma (next column)
+
+**Trigger:** After comma in SELECT list
+
+**Show:**
+- All columns (unqualified if single table, qualified with alias-first if multiple tables) (filtered by prefix if present)
+ - **Note:** With prefix, see **Generic Prefix Matching** section for table-name expansion rules
+- All functions (filtered by prefix if present)
+
+**Special case - previous item is qualified:**
+- If the select item immediately before the comma is a qualified column reference (`table.column` or `alias.column`), suggest columns from that same qualifier first.
+- This applies even when there is no FROM/JOIN scope and no prefix.
+- Do NOT include database-wide columns from other tables unless a prefix exists.
+
+**Rationale:** The user has already chosen a specific table/alias by qualifying the previous select item, so suggesting the remaining columns from the same qualifier is useful and avoids noisy DB-wide suggestions.
+
+**Examples:**
+```sql
+-- Single table, no prefix: unqualified
+SELECT col1, |
+→ id, name, email, ... (single table: unqualified)
+→ COUNT, SUM, AVG, ...
+
+-- Single table, no FROM in current statement, no prefix: unqualified
+SELECT * FROM users u WHERE id = 1; SELECT id, |
+→ id, name, email, ... (single table: unqualified)
+→ COUNT, SUM, AVG, ...
+
+-- Single table, prefix matches column name: unqualified
+SELECT id, n|
+→ name (column-name match, unqualified)
+
+-- Single table, prefix matches table name: qualified (table-name expansion)
+SELECT * FROM users; SELECT id, u|
+→ users.id, users.name, users.email, users.password, users.is_enabled, users.created_at (table-name expansion, qualified)
+→ UPPER, UUID, UNIX_TIMESTAMP
+
+-- Multiple tables: qualified
+SELECT * FROM users u JOIN orders o ON u.id = o.user_id; SELECT u.id, |
+→ u.id, u.name, u.email, o.user_id, o.total, o.created_at (multiple tables: qualified)
+→ COUNT, SUM, AVG, ...
+```
+
+#### 3d. After complete column (space after column)
+
+**Trigger:** After a complete column name (with or without table prefix) followed by space
+
+**Show:**
+- Keywords ONLY: `FROM`, `WHERE`, `AS`, `LIMIT`, `ORDER BY`, `GROUP BY`, `HAVING`
+- `AS` only if the current select item has no alias yet
+- **IMPORTANT:** NO functions (COUNT, SUM, UPPER, etc.) - user has completed selection
+
+**Note:** If alias presence cannot be reliably detected in incomplete SQL, default to offering `AS` (non-breaking UX).
+
+**Rationale:** Whitespace after a complete column indicates "selection complete" - user wants to move to next clause, not continue with functions.
+
+**Examples:**
+```sql
+SELECT id |
+→ FROM, WHERE, AS, LIMIT, ORDER BY, GROUP BY, HAVING
+→ NOT: COUNT, SUM, UPPER, etc.
+
+SELECT id AS user_id |
+→ FROM, WHERE, LIMIT, ORDER BY, GROUP BY, HAVING (AS excluded - alias already present)
+
+SELECT users.id |
+→ FROM, WHERE, AS, LIMIT, ORDER BY, GROUP BY, HAVING
+→ NOT: COUNT, SUM, UPPER, etc.
+
+SELECT table.column |
+→ FROM, WHERE, AS, LIMIT, ORDER BY, GROUP BY, HAVING
+→ NOT: functions
+```
+
+---
+
+### 4. FROM_CLAUSE (After FROM)
+
+**Trigger:** After `FROM` and before `WHERE`/`JOIN`
+
+#### 4a. Without prefix
+
+**Show:**
+- CTE names (if available from WITH clause)
+- All physical tables
+- `CURRENT_TABLE` (if set and not already present in current statement)
+
+**Prioritization/Filtering:** If SELECT list contains qualified columns (e.g., `SELECT users.id`), suggest ONLY those referenced tables in FROM suggestions. When multiple tables are referenced, follow their left-to-right appearance order in the SELECT list.
+
+**Examples:**
+```sql
+SELECT * FROM |
+→ customers, orders, products, users (alphabetical - no prioritization)
+
+SELECT users.id FROM |
+→ users (ONLY referenced table from qualified SELECT column)
+
+SELECT orders.total, users.name FROM |
+→ orders, users (ONLY referenced tables, left-to-right from SELECT)
+
+WITH active_users AS (SELECT * FROM users WHERE status = 'active')
+SELECT * FROM |
+→ active_users, users, orders, products, ...
+```
+
+**Note:** Derived tables are not suggested as candidates to type in FROM/JOIN in v1 (they are inline subqueries, not selectable by name); but if present in the query, their alias contributes columns to scope.
+
+**CURRENT_TABLE handling:**
+
+`CURRENT_TABLE` may be suggested if:
+- It is set
+- It is not already present in the current statement
+
+**Table re-suggestion policy (self-join support):**
+
+Physical tables already present in FROM/JOIN:
+- **WITHOUT alias**: MUST NOT be suggested again (e.g., `FROM products, |` → products excluded)
+- **WITH alias**: MAY be suggested again for self-join (e.g., `FROM products p, |` → products allowed)
+
+**Rationale:** FROM_CLAUSE is a table-selection context (scope construction). When users explicitly type qualified columns in SELECT, suggesting only referenced tables reduces ambiguous choices (e.g., `product` vs `products`) and avoids accidental wrong-table selection. Tables without aliases cannot be re-used (SQL syntax error), but tables with aliases enable self-join patterns (e.g., `FROM users u1 JOIN users u2`).
+
+#### 4b. With prefix
+
+**Show:**
+- CTE names starting with the prefix
+- Physical tables starting with the prefix
+- `CURRENT_TABLE` (if set, matches prefix, and not already present in current statement)
+
+**Prioritization/Filtering:** Same as 4a - if SELECT list contains qualified columns, filter to ONLY referenced tables, then apply prefix matching within that set. When multiple tables are referenced, follow their left-to-right appearance order in the SELECT list.
+
+**Examples:**
+```sql
+SELECT * FROM u|
+→ users
+
+SELECT users.column FROM u|
+→ users (ONLY referenced table matches prefix)
+
+SELECT products.price, users.name FROM u|
+→ users (ONLY referenced table matching prefix)
+
+SELECT orders.total, users.name FROM o|
+→ orders (ONLY referenced table matching prefix)
+
+WITH active_users AS (...)
+SELECT * FROM a|
+→ active_users
+```
+
+#### 4c. After comma (multiple tables)
+
+**Trigger:** After comma in FROM clause
+
+**Show:**
+- CTE names (if available)
+- All physical tables (filtered by prefix if present)
+
+**Examples:**
+```sql
+SELECT * FROM users, |
+→ orders, products, customers, ...
+
+WITH active_users AS (...)
+SELECT * FROM users, |
+→ active_users, orders, products, ...
+
+SELECT * FROM users, o|
+→ orders
+```
+
+#### 4d. After table name (space after table)
+
+**Trigger:** After a complete table name followed by space
+
+**Show:**
+- Keywords: `JOIN`, `INNER JOIN`, `LEFT JOIN`, `RIGHT JOIN`, `CROSS JOIN`, `WHERE`, `GROUP BY`, `ORDER BY`, `LIMIT`
+- `AS` (only if the table doesn't already have an alias)
+
+**Alias detection (best-effort):**
+- SQL allows aliases with or without `AS` keyword (e.g., `FROM users u` or `FROM users AS u`)
+- Autocomplete should treat both forms as "alias present" to avoid suggesting `AS` when alias already exists
+- Detection: if token after table name is a valid identifier (not a keyword), treat it as an alias
+
+**Examples:**
+```sql
+SELECT * FROM users |
+→ JOIN, INNER JOIN, LEFT JOIN, RIGHT JOIN, CROSS JOIN, AS, WHERE, GROUP BY, ORDER BY, LIMIT
+ (AS included because no alias defined yet)
+
+SELECT * FROM users AS u |
+→ JOIN, INNER JOIN, LEFT JOIN, RIGHT JOIN, CROSS JOIN, WHERE, GROUP BY, ORDER BY, LIMIT
+ (AS excluded because alias 'u' already exists)
+
+SELECT * FROM users u |
+→ JOIN, INNER JOIN, LEFT JOIN, RIGHT JOIN, CROSS JOIN, WHERE, GROUP BY, ORDER BY, LIMIT
+ (AS excluded because alias 'u' already exists, even without AS keyword)
+```
+
+#### 4e. After AS (alias definition)
+
+**Trigger:** After `AS` keyword in FROM clause
+
+**Show:**
+- Nothing (empty list)
+
+**Rationale:** User is typing a custom alias name. No suggestions should interfere with free-form text input.
+
+**Examples:**
+```sql
+SELECT * FROM users AS |
+→ (no suggestions - user types alias freely)
+
+SELECT * FROM users AS u|
+→ (no suggestions - user is typing alias name)
+
+SELECT * FROM users AS u |
+→ JOIN, INNER JOIN, LEFT JOIN, RIGHT JOIN, WHERE, GROUP BY, ORDER BY, LIMIT
+ (alias complete, suggest next clauses)
+```
+
+**Note:** Once the alias is complete (followed by space), normal clause keyword suggestions resume.
+
+---
+
+### 5. JOIN_CLAUSE (After JOIN)
+
+**JOIN_CLAUSE is a table-selection context (like FROM).**
+
+It suggests tables, not columns.
+
+**Allowed suggestions:**
+- CTE names
+- Physical tables
+- `CURRENT_TABLE` (as a convenience table candidate, if not already present in the statement)
+
+**Important:** JOIN_CLAUSE is part of scope construction. It may include `CURRENT_TABLE` even if other scope tables already exist. Column suggestion logic must NOT run in this context.
+
+**Trigger:** After `JOIN`, `INNER JOIN`, `LEFT JOIN`, `RIGHT JOIN`, etc.
+
+#### 5a. Without prefix
+
+**Show:**
+- CTE names (if available from WITH clause)
+- All physical tables
+- `CURRENT_TABLE` (if set and not already present in current statement)
+
+**Examples:**
+```sql
+SELECT * FROM users JOIN |
+→ orders, products, customers, ...
+
+WITH active_users AS (...)
+SELECT * FROM users JOIN |
+→ active_users, orders, products, ...
+```
+
+**Note:** Derived tables are not suggested as candidates to type in FROM/JOIN in v1 (they are inline subqueries, not selectable by name); but if present in the query, their alias contributes columns to scope.
+
+**CURRENT_TABLE handling:**
+
+`CURRENT_TABLE` may be suggested if:
+- It is set
+- It is not already present in the current statement
+
+**Table re-suggestion policy (self-join support):**
+
+Physical tables already present in FROM/JOIN:
+- **WITHOUT alias**: MUST NOT be suggested again (e.g., `FROM orders JOIN |` → orders excluded)
+- **WITH alias**: MAY be suggested again for self-join (e.g., `FROM orders o JOIN |` → orders allowed)
+
+**Rationale:** JOIN_CLAUSE is a table-selection context (scope extension). It follows the same rule as FROM_CLAUSE. Tables without aliases cannot be re-used (SQL syntax error), but tables with aliases enable self-join patterns (e.g., `FROM users u1 JOIN users u2`).
+
+#### 5b. With prefix
+
+**Show:**
+- CTE names starting with the prefix
+- Physical tables starting with the prefix
+- `CURRENT_TABLE` (if set, matches prefix, and not already present in current statement)
+
+**Examples:**
+```sql
+SELECT * FROM users JOIN o|
+→ orders
+
+WITH active_users AS (...)
+SELECT * FROM users u LEFT JOIN a|
+→ active_users
+```
+
+#### 5c. After table name (space after table)
+
+**Trigger:** After a complete table name in JOIN clause followed by space
+
+**Show:**
+- Keywords: `AS`, `ON`, `USING`
+- `AS` (only if the table doesn't already have an alias)
+
+**Alias detection (best-effort):**
+- SQL allows aliases with or without `AS` keyword (e.g., `JOIN orders o` or `JOIN orders AS o`)
+- Autocomplete should treat both forms as "alias present" to avoid suggesting `AS` when alias already exists
+- Detection: if token after table name is a valid identifier (not a keyword), treat it as an alias
+
+**Examples:**
+```sql
+SELECT * FROM users JOIN orders |
+→ AS, ON, USING
+ (AS included because no alias defined yet)
+
+SELECT * FROM users u LEFT JOIN products AS p |
+→ ON, USING
+ (AS excluded because alias 'p' already exists)
+
+SELECT * FROM users u LEFT JOIN products p |
+→ ON, USING
+ (AS excluded because alias 'p' already exists, even without AS keyword)
+```
+
+---
+
+### 5-JOIN_ON. JOIN_ON (Expression Context)
+
+**JOIN_ON is an expression context.**
+
+It suggests columns and functions.
+
+**Column suggestions MUST be restricted strictly to tables in scope:**
+- FROM tables
+- JOIN tables
+- CTEs referenced in the statement
+- Derived tables (subquery aliases)
+
+**Critical restrictions:**
+
+See **Scope-Restricted Expression Contexts** section for complete rules.
+
+---
+
+#### 5d. After ON (without prefix)
+
+**Trigger:** After `ON` keyword in JOIN clause
+
+**Show:**
+- FK join-condition hints (complete expressions) first, when a foreign key relationship exists between the current JOIN table and already scoped tables
+ - Direction: `left.pk = right.fk` when right-side table owns the FK
+ - Alias-first qualification always applies in hints
+- Columns from scope tables only (qualified with alias-first)
+- All functions
+
+**Examples:**
+```sql
+SELECT * FROM users JOIN orders ON |
+→ users.id, users.name, users.email, orders.id, orders.user_id, orders.total, orders.created_at
+→ COUNT, SUM, AVG, ...
+
+SELECT * FROM users u JOIN orders o ON |
+→ u.id = o.user_id (FK hint first)
+→ u.id, u.name, u.email, o.id, o.user_id, o.total, o.created_at
+→ COUNT, SUM, AVG, ...
+```
+
+#### 5e. After ON (with prefix)
+
+**Trigger:** After `ON` keyword with prefix in JOIN clause
+
+**Show:**
+- Prefix-matching FK join-condition hints first (if any)
+- Columns matching the prefix (see **Generic Prefix Matching for Column Contexts** section)
+- Functions matching the prefix
+
+**Examples:**
+
+**Generic prefix (no alias exact match):**
+```sql
+SELECT * FROM users JOIN orders ON u|
+→ Context: JOIN_ON (scope-restricted)
+→ Table-name expansion: users.* (all columns from scope table 'users')
+→ Column-name matching: orders.user_id (scope table column only)
+→ Functions: UPPER, UUID, UNIX_TIMESTAMP
+→ (Database-wide columns excluded - scope restriction active)
+```
+
+**Alias exact match:**
+```sql
+SELECT * FROM users u JOIN orders o ON u|
+→ Context: JOIN_ON (scope-restricted)
+→ Alias-exact-match mode (u == alias 'u')
+→ u.id, u.name, u.email, u.password, u.is_enabled, u.created_at
+→ UPPER, UUID, UNIX_TIMESTAMP
+```
+
+#### 5f. After comparison operator
+
+**Trigger:** After `=`, `!=`, `<`, `>`, etc. in ON clause
+
+**Show:**
+- Literal keywords: `NULL`, `TRUE`, `FALSE`
+- Columns from scope tables only (unqualified if single table, qualified with alias-first if multiple tables) (filtered by prefix if present)
+- All functions (filtered by prefix if present)
+
+**Operator context rule applies:** The column **immediately to the LEFT** of the current operator MUST NOT be suggested (see **Scope-Restricted Expression Contexts** section for details).
+
+**Column ranking (HeidiSQL-like UX):**
+- Prioritize columns from the **other-side table** (typically the table being joined)
+- Then columns from other tables in scope
+- This helps users quickly find the matching column
+
+**Other-side table determination:**
+- If left side of operator has qualified column (e.g., `u.id = |`) → other-side = all other tables in scope, prioritizing tables introduced by current JOIN
+- If left side is from derived table/CTE → other-side = same logic
+- If left side is not recognizable → fallback to scope table ordering (FROM > JOIN)
+
+**Critical:** Database-wide columns and `CURRENT_TABLE` are excluded (scope restriction active).
+
+**Examples:**
+```sql
+SELECT * FROM users JOIN orders ON users.id = |
+→ NULL, TRUE, FALSE
+→ orders.user_id, orders.id, orders.total, orders.created_at, ... (orders columns prioritized - other-side table)
+→ users.name, users.email, users.password, users.is_enabled, users.created_at, ... (users columns after)
+→ (users.id excluded - immediately left of operator)
+
+SELECT * FROM users u JOIN orders o ON u.id = |
+→ NULL, TRUE, FALSE
+→ o.user_id, o.id, o.total, o.created_at, ... (orders columns prioritized - other-side table)
+→ u.name, u.email, u.password, u.is_enabled, u.created_at, ... (users columns after)
+→ (u.id excluded - immediately left of operator)
+
+SELECT * FROM users u JOIN orders o ON u.id = o|
+→ o.user_id, o.id
+```
+
+#### 5g. After complete expression (logical operators)
+
+**Trigger:** After a complete condition/expression followed by space in ON clause
+
+**Show:**
+- Logical keywords: `AND`, `OR`, `NOT`
+- Other keywords: `WHERE`, `ORDER BY`, `GROUP BY`, `LIMIT`
+
+**Examples:**
+```sql
+SELECT * FROM users JOIN orders ON users.id = orders.user_id |
+→ AND, OR, WHERE, ORDER BY, LIMIT
+
+SELECT * FROM users u JOIN orders o ON u.id = o.user_id |
+→ AND, OR, NOT, WHERE, ORDER BY, LIMIT
+```
+
+---
+
+### 6. WHERE_CLAUSE (After WHERE)
+
+**Trigger:** After `WHERE`, `AND`, `OR`
+

+**Trigger:** After `=`, `!=`, `<`, `>`, `<=`, `>=`, `LIKE`, `IN`, etc. in WHERE clause
+
+**Show:**
+- Literal keywords: `NULL`, `TRUE`, `FALSE`, `CURRENT_DATE`, `CURRENT_TIME`, `CURRENT_TIMESTAMP`
+- All columns (unqualified if single table, qualified with alias-first if multiple tables) (filtered by prefix if present)
+- All functions (filtered by prefix if present)
+
+**Operator context rule applies:** The column **immediately to the LEFT** of the current operator MUST NOT be suggested (see **Scope-Restricted Expression Contexts** section for details).

+→ CURRENT_DATE, CURRENT_TIME, CURRENT_TIMESTAMP
+→ id, name, email, password, is_enabled, ... (single table: unqualified)
+→ (created_at excluded - immediately left of operator)

+
+### 7. ORDER_BY_CLAUSE (After ORDER BY)
+
+**Trigger:** After `ORDER BY`
+
+**Important:** Only show columns from tables specified in FROM and JOIN clauses (using alias if defined, otherwise table name).
+
+**MUST NOT suggest literals:** Do NOT suggest `NULL`, `TRUE`, `FALSE`, `CURRENT_DATE`, `CURRENT_TIME`, `CURRENT_TIMESTAMP` in ORDER BY context. Ordering by constants is meaningless as all rows would have the same sort value.
+
+#### 7a. Without prefix
+
+**Show:**
+- Columns in scope (unqualified if single table, qualified with alias-first if multiple tables)
+ - **Note:** With prefix, see **Generic Prefix Matching** section for table-name expansion rules
+- Functions
+
+**MUST NOT suggest sort direction keywords:** Do NOT suggest `ASC`, `DESC`, `NULLS FIRST`, `NULLS LAST` in `ORDER BY |` without a column specified. These keywords are only meaningful after a column/expression (see section 7c).
+
+**Ordering:** Columns first, then functions. Users must choose the column before specifying sort direction.

+
+### 8. GROUP_BY_CLAUSE (After GROUP BY)
+
+**Trigger:** After `GROUP BY`
+
+**Important:** Only show columns from tables specified in FROM and JOIN clauses (using alias if defined, otherwise table name).
+
+#### 8a. Without prefix
+
+**Show:**
+- Columns in scope (unqualified if single table, qualified with alias-first if multiple tables)

+
+### 9. HAVING_CLAUSE (After HAVING)
+
+**Trigger:** After `HAVING`
+
+**Important:** Only show columns from tables specified in FROM and JOIN clauses. Focus on aggregate functions.
+
+**Aggregate functions definition:** Predefined set of functions per SQL dialect that perform aggregation operations. Standard set includes: `COUNT`, `SUM`, `AVG`, `MAX`, `MIN`. Vendor-specific additions: `GROUP_CONCAT` (MySQL), `STRING_AGG` (PostgreSQL), `LISTAGG` (Oracle), `ARRAY_AGG`, etc. This list is dialect-dependent and should be maintained as a constant set in the implementation.
+
+#### 9a. Without prefix
+
+**Show:**
+- Aggregate functions (prioritized): from the predefined aggregate functions set for current dialect
+- Columns in scope (unqualified if single table, qualified with alias-first if multiple tables)
+ - **Note:** With prefix, see **Generic Prefix Matching** section for table-name expansion rules
+- Other functions (non-aggregate)
+
+**Ordering:** Aggregate functions first (alphabetical), then columns (schema order - NOT alphabetical), then other functions (alphabetical).
+
+**Rationale:** HAVING typically filters aggregates; prioritizing aggregate functions reduces keystrokes and improves UX.
+
+**Note:** Columns preserve their table definition order (ordinal_position), consistent with global ordering rules.
+
+**Examples:**
+```sql
+SELECT status, COUNT(*) FROM users GROUP BY status HAVING |
+→ COUNT, SUM, AVG, MAX, MIN, ... (aggregate functions first, alphabetical)
+→ id, name, email, ... (single table: unqualified, schema order)
+→ CONCAT, UPPER, LOWER, ... (other functions, alphabetical)
+```
+
+#### 9b. With prefix
+
+**Show:**
+- Aggregate functions matching the prefix (prioritized): from the predefined aggregate functions set for current dialect
+- Columns matching the prefix (see **Generic Prefix Matching for Column Contexts** section)
+- Other functions matching the prefix (non-aggregate)
+
+**Ordering:** Aggregate functions first (alphabetical), then columns (schema order - NOT alphabetical), then other functions (alphabetical).
+
+**Note:** Columns preserve their table definition order (ordinal_position), consistent with global ordering rules.
+
+**Examples:**
+```sql
+SELECT status, COUNT(*) FROM users GROUP BY status HAVING c|
+→ COUNT (aggregate function first, alphabetical)
+→ created_at (single table: unqualified, scope column matching prefix 'c')
+→ CONCAT, COALESCE (other functions, alphabetical)
+→ (DB-wide columns excluded - HAVING is scope-restricted expression context)
+```
+
+#### 9c. After comparison operator
+
+**Show:**
+- Literal keywords: `NULL`, `TRUE`, `FALSE`
+- Aggregate functions
+- Columns
+- Numbers (user types directly)
+
+**Examples:**
+```sql
+SELECT status, COUNT(*) FROM users GROUP BY status HAVING COUNT(*) > |
+→ NULL, TRUE, FALSE
+→ COUNT, SUM, AVG, ...
+→ (user can type number)
+```
+
+#### 9d. After complete expression (logical operators)
+
+**Trigger:** After a complete condition/expression followed by space
+
+**Show:**
+- Logical keywords: `AND`, `OR`, `NOT`, `EXISTS`
+- Other keywords: `ORDER BY`, `LIMIT`
+
+**Examples:**
+```sql
+SELECT status, COUNT(*) FROM users GROUP BY status HAVING COUNT(*) > 10 |
+→ AND, OR, ORDER BY, LIMIT
+
+SELECT status, COUNT(*) FROM users GROUP BY status HAVING SUM(total) > 1000 |
+→ AND, OR, NOT, ORDER BY, LIMIT
+```
+
+---
+
+### 10. LIMIT_OFFSET_CLAUSE (After LIMIT or OFFSET)
+
+**Trigger:** After `LIMIT` or `OFFSET`
+
+**Show:**
+- Nothing (user types number directly)
+
+**Examples:**
+```sql
+SELECT * FROM users LIMIT |
+→ (no suggestions - user types number)
+
+SELECT * FROM users LIMIT 10 OFFSET |
+→ (no suggestions - user types number)
+```
+
+**Note:** No autocomplete suggestions in this context. User types numeric values freely. This avoids noise and keeps the implementation simple.
+
+---
+
+## Ordering Rules
+
+Suggestions are always ordered by priority:
+
+**Ordering Rules apply after applying scope restrictions.**
+
+**CURRENT_TABLE group inclusion is context-dependent:**
+- **Expression contexts (JOIN_ON, WHERE, ORDER_BY, GROUP_BY, HAVING):** CURRENT_TABLE group MUST be omitted unless `CURRENT_TABLE` is in scope
+- **SELECT_LIST without scope tables:** CURRENT_TABLE group MUST be included (if set)
+- **SELECT_LIST with scope tables:** CURRENT_TABLE group MUST be included ONLY if `CURRENT_TABLE` is in scope
+- **Table-selection contexts (FROM_CLAUSE, JOIN_CLAUSE):** Not applicable (these suggest tables, not columns)
+
+**Column display format:**
+- **Single table in scope:** Use unqualified column names (e.g., `id`, `name`)
+- **Multiple tables in scope:** Use `alias.column` when the table has an alias in the current statement; otherwise use `table.column`
+- **Exception:** Dot-completion always returns unqualified column names (see **Dot-Completion** section)
+
+**Exception:** In HAVING clause context, aggregate functions are prioritized before columns (see section 9a, 9b for details). This is the only context where functions appear before columns.
+
+**Column ordering reminder:** See "Important Note on Column Ordering in Examples" section at the beginning of this document. All columns preserve schema order (ordinal_position), NOT alphabetical order.
+
+1. **Columns from CURRENT_TABLE** (if set in context, e.g., table editor)
+ - **Single table in scope:** Unqualified (e.g., `id`, `name`)
+ - **Multiple tables in scope:** Use `alias.column` format if the table has an alias in the current query, otherwise `table.column`
+ - Columns preserve their definition order (ordinal position in the table schema). They must NOT be reordered alphabetically.
+
+2. **Columns from tables in FROM clause** (if any)
+ - Includes: derived tables (subquery aliases), CTEs, physical tables
+ - Priority within FROM: derived tables > CTEs > physical tables (see **Tables in Scope Definition** section)
+ - **Single table in scope:** Unqualified (e.g., `id`, `name`)
+ - **Multiple tables in scope:** Use `alias.column` format if the table has an alias, otherwise `table.column`
+ - Columns preserve their definition order (ordinal position in the table schema). They must NOT be reordered alphabetically.
+ - When multiple FROM tables exist, follow their appearance order in the query; within each table, preserve column definition order.
+
+3. **Columns from tables in JOIN clause** (if any)
+ - Includes: derived tables (subquery aliases), CTEs, physical tables
+ - Priority within JOIN: derived tables > CTEs > physical tables (see **Tables in Scope Definition** section)
+ - **Multiple tables in scope:** Use `alias.column` format if the table has an alias, otherwise `table.column`
+ - Columns preserve their definition order (ordinal position in the table schema). They must NOT be reordered alphabetically.
+ - When multiple JOIN tables exist, follow their appearance order in the query; within each table, preserve column definition order.
+ - **Note:** JOIN clause always implies multiple tables in scope (FROM + JOIN), so columns are always qualified
+
+4. **All table.column from database** (all other tables not in FROM/JOIN)
+ - **CRITICAL: Group 4 eligibility is context-dependent:**
+ - ✅ **Eligible in SELECT_LIST when NO scope tables exist** (and only with prefix - guardrail against noise)
+ - ❌ **NOT eligible in SELECT_LIST when scope tables exist** (scope restriction active)
+ - ❌ **NOT eligible in scope-restricted expression contexts** (WHERE, JOIN_ON, ORDER_BY, GROUP_BY, HAVING)
+ - ❌ **NOT applicable in table-selection contexts** (FROM_CLAUSE, JOIN_CLAUSE suggest tables, not columns)
+ - Always use `table.column` format (no aliases for tables not in query)
+ - Columns preserve their definition order (ordinal position in the table schema). They must NOT be reordered alphabetically.
+ - Database-wide tables follow a deterministic stable order (schema order or internal stable ordering); within each table, preserve column definition order.
+ - **Performance guardrail (applies ONLY to this group when eligible):** If no prefix and total suggestions exceed threshold (400 items), skip this group to avoid lag in large databases
+ - **No prefix definition:** prefix is `None` OR empty string after trimming whitespace
+ - The cap applies only to group 4 (DB-wide columns). Groups 1-3 (CURRENT_TABLE, FROM, JOIN) are always included in full (already loaded/scoped).
+ - With prefix: always include this group when eligible (filtered results are manageable)
+
+5. **Functions**
+ - Alphabetically within this group
+
+6. **Out-of-Scope Table Hints** (SELECT_LIST with scope only)
+ - Format: `table_name (+ Add via FROM or JOIN)`
+ - Only when prefix matches DB-wide tables but no scope tables/columns
+ - See **Out-of-Scope Table Hints** section for details
+
+7. **Keywords**
+ - Alphabetically within this group
+
+---
+
+### Alias Prefix Disambiguation
+
+**Applies in expression contexts** (WHERE, ON, ORDER BY, GROUP BY, HAVING, SELECT_LIST)
+
+**Note:** In SELECT_LIST, alias-prefix disambiguation applies only when FROM/JOIN tables are available in the current statement. Without FROM/JOIN, SELECT_LIST shows functions + keywords (see section 3a).
+
+**Note:** In ORDER BY / GROUP BY, exact alias match still activates alias-prefix mode (same as other contexts). However, this is most relevant when the prefix is immediately followed by `.` (dot-completion) or when the typed token exactly equals an alias. Otherwise generic prefix matching applies (column names are common in these contexts).
+
+**Critical: Exact Match Rule**
+
+Alias-prefix mode activates **only if the token exactly equals an alias** (not startswith). This avoids ambiguity with multiple aliases.
+
+**Rule:**
+- `token == alias` → alias-prefix mode ✅
+- `token.startswith(alias)` → generic prefix mode ❌
+
+**Why exact match?**
+- Avoids ambiguity with multiple aliases (e.g., `u` and `us`)
+- Prevents false positives (e.g., `user|` should not trigger alias `u`)
+
+**Behavior:**
+- If prefix **exactly equals** an alias: show only that alias' columns first (e.g., `u.id`, `u.name`)
+- If prefix does NOT exactly match an alias: treat as generic prefix (match table name, column name, or function name)
+
+**Deduplication in alias-exact-match mode:**
+- When alias-exact-match mode is active, do NOT also emit the same columns qualified with the base table name
+- Deduplicate by underlying column identity (e.g., if showing `u.id`, do not also show `users.id`)
+- This avoids redundancy and keeps suggestions clean
+
+**Interaction with CURRENT_TABLE:**
+- In alias-prefix mode, CURRENT_TABLE priority is ignored; alias columns are always ranked first
+- This avoids unexpected behavior in table editor when using aliases
+
+**Examples:**
+
+**Exact match - Alias-prefix mode:**
+```sql
+SELECT * FROM users u JOIN orders o WHERE u|
+→ token = "u"
+→ alias "u" exists → exact match ✅
+→ u.id, u.name, u.email, ... (alias 'u' columns prioritized)
+→ UPPER, UUID (functions matching 'u')
+→ (do not show users.id, users.name - avoid redundancy)
+```
+
+**No exact match - Generic prefix mode:**
+```sql
+SELECT * FROM users u JOIN orders o WHERE us|
+→ token = "us"
+→ aliases: u, o
+→ "us" != "u" and "us" != "o" → no exact match ❌
+→ users.id, users.name, users.email, users.password, users.is_enabled, users.created_at, ... (table starts with 'us')
+→ (generic prefix matching)
+
+SELECT * FROM users u WHERE user|
+→ token = "user"
+→ alias "u" exists but "user" != "u" → no exact match ❌
+→ Columns: (none - single table, no columns start with 'user') (single table: unqualified)
+→ Functions: (none starting with 'user')
+→ (generic prefix matching, NOT alias-prefix)
+→ (DB-wide columns excluded - WHERE is scope-restricted)
+
+SELECT * FROM users u WHERE up|
+→ token = "up"
+→ alias "u" exists but "up" != "u" → no exact match ❌
+→ UPPER (function starts with 'up')
+→ (generic prefix matching - user is typing a function, NOT using the alias)
+```
+
+**No alias in query - Generic prefix mode:**
+```sql
+SELECT * FROM users JOIN orders ON u|
+→ token = "u"
+→ Context: JOIN_ON (scope-restricted)
+→ no aliases defined → generic prefix
+→ users.id, users.name, users.email, users.password, users.is_enabled, users.created_at (multiple tables: qualified)
+→ orders.user_id (scope table column starts with 'u')
+→ UPPER, UUID (functions start with 'u')
+→ (Database-wide columns excluded - scope restriction active)
+```
+
+**Note:** This rule applies only to tokens without dot. `u.|` triggers Dot-Completion, not alias-prefix disambiguation.
+
+---
+
+### Generic Prefix Matching for Column Contexts
+
+**Applies to all column-expression contexts:** SELECT_LIST, WHERE_CLAUSE, JOIN_ON, ORDER_BY, GROUP_BY, HAVING, and any additional expression contexts where columns can be inserted.
+
+**When NOT in dot-completion and NOT in alias-exact-match mode:**
+
+Given a prefix P (token immediately before cursor, without '.'):
+
+**Return column suggestions that include BOTH:**
+
+**B) Column-name match:**
+- For EVERY column C (from all tables in scope and all other database tables) whose column name startswith(P), return it as a column suggestion
+- **Qualification:**
+ - **Single table in scope:** Unqualified (e.g., `name`)
+ - **Multiple tables in scope:** Qualified with `alias.column` if table has alias, otherwise `table.column`
+
+**A) Table-name match expansion:**
+- For EVERY table T whose name startswith(P), return ALL columns of T as column suggestions
+- **Qualification:** Always qualified with `alias.column` if table has alias, otherwise `table.column` (even for single table)
+- **Rationale:** Qualified names indicate the match is from table name, helping users discover dot-completion
+
+**Order when BOTH B and A match (prefix matches both column names AND table name):**
+1. **Column-name matches unqualified** (rule B, single table only)
+2. **Column-name matches qualified** (same columns as #1, but qualified)
+3. **Table-name expansion remaining columns qualified** (rule A, excluding columns already shown in #1 and #2)
+4. **Functions**
+
+**Order when ONLY B matches (prefix matches column names but NOT table name):**
+1. **Column-name matches** (unqualified if single table, qualified if multiple tables)
+2. **Functions**
+
+**Order when ONLY A matches (prefix matches table name but NOT column names):**
+1. **Table-name expansion all columns qualified** (rule A)
+2. **Functions**
+
+**Scope restriction:**
+
+**Scope-restricted expression contexts (WHERE, JOIN_ON, ORDER_BY, GROUP_BY, HAVING):**
+
+**Hard line:** In scope-restricted expression contexts, both table-name expansion and column-name matching MUST be computed over scope tables only.
+
+See **Scope-Restricted Expression Contexts** section for complete rules.
+
+**SELECT_LIST without scope tables:**
+- `CURRENT_TABLE` columns MUST be included first (if set)
+- Database-wide table-name expansion and column-name matching are included **ONLY when prefix exists**
+- **CRITICAL: When no prefix exists, DB-wide columns MUST NOT be shown (guardrail against noise)**
+- **With prefix matching order:**
+ 1. **CURRENT_TABLE table-name expansion** (if CURRENT_TABLE name matches prefix)
+ 2. **Other DB-wide table-name expansions** (tables whose names match prefix)
+ 3. **Column-name matching from all DB tables** (columns whose names match prefix)
+ 4. **Functions**
+
+**SELECT_LIST with scope tables:**
+- `CURRENT_TABLE` columns MUST be included ONLY if `CURRENT_TABLE` is in scope
+- Database-wide columns MUST NOT be suggested (regardless of prefix)
+- Scope table columns are included with alias-first qualification
+- **Exception:** If prefix matches DB-wide tables but no scope tables/columns, suggest Out-of-Scope Table Hints instead
+
+**Important rules:**
+- Do NOT suggest bare table names in column-expression contexts; only columns (qualified)
+ - **Exception:** Out-of-Scope Table Hints (see **Out-of-Scope Table Hints** section) are a special suggestion kind
+- Deduplicate identical suggestions (if a column appears via both A and B, show it once)
+- Apply global Ordering Rules (CURRENT_TABLE > FROM > JOIN > DB > FUNCTIONS > TABLE_HINTS > KEYWORDS)
+ - **Note:** DB group only applies when no scope exists; TABLE_HINTS only in SELECT_LIST with scope
+- Performance guardrail: see Ordering Rules group 4 (applies only to DB-wide columns when no prefix)
+
+**Examples:**
+
+**SELECT_LIST without scope, with CURRENT_TABLE and prefix:**
+```sql
+-- Assume CURRENT_TABLE = users, prefix = "u"
+SELECT u|
+→ Prefix: "u"
+→ Context: SELECT_LIST (no scope → DB-wide columns allowed with prefix)
+→ CURRENT_TABLE table-name expansion: users.id, users.name, users.email, users.status, users.created_at (FIRST)
+→ Other table-name expansion: user_sessions.id, user_sessions.user_id, user_sessions.session_token, user_sessions.expires_at (SECOND)
+→ Column-name matching: orders.user_id, products.unit_price (THIRD)
+→ Functions: UNIX_TIMESTAMP, UPPER, UUID (FOURTH)
+```
+
+**SELECT_LIST with scope tables (database-wide columns excluded):**
+```sql
+SELECT u| FROM orders
+→ Prefix: "u"
+→ Context: SELECT_LIST (scope exists → database-wide columns excluded)
+→ Scope column-name matching: orders.user_id (scope table column starts with 'u')
+→ Functions: UPPER, UUID, UNIX_TIMESTAMP
+→ Out-of-Scope Table Hints: users + Add via FROM/JOIN (prefix matches DB table but not in scope)
+→ Combined: orders.user_id, UPPER, UUID, UNIX_TIMESTAMP, users (hint)
+```
+
+**WHERE with scope tables (database-wide columns excluded):**
+```sql
+SELECT * FROM users u WHERE us|
+→ Prefix: "us"
+→ Context: WHERE (scope tables exist → database-wide columns disabled)
+→ Alias "u" exists but "us" != "u" → NOT alias-exact-match mode
+→ Table-name expansion: users table starts with 'us' → u.id, u.name, u.email, u.password, u.is_enabled, u.created_at (uses alias)
+→ Column-name matching: restricted to scope tables only (none in this example)
+→ Combined: u.id, u.name, u.email, u.password, u.is_enabled, u.created_at
+```
+
+**Deduplication example:**
+```sql
+SELECT u| FROM users
+→ Table-name expansion: users.* (all columns)
+→ Column-name matching: users.updated_at (if such column exists and starts with 'u')
+→ Deduplication: users.updated_at appears in both → show once
+```
+
+**Applies to all column contexts:**
+- SELECT_LIST: `SELECT u|` or `SELECT u| FROM users`
+- WHERE: `SELECT * FROM users WHERE u|`
+- JOIN ON: `SELECT * FROM users u JOIN orders o ON u.id = o.u|`
+- ORDER BY: `SELECT * FROM users ORDER BY u|`
+- GROUP BY: `SELECT * FROM users GROUP BY u|`
+- HAVING: `SELECT status, COUNT(*) FROM users GROUP BY status HAVING u|`
+
+**Example - Alias-prefix overrides CURRENT_TABLE:**
+```sql
+-- CURRENT_TABLE = users (in table editor)
+SELECT * FROM users u JOIN orders o WHERE u|
+→ token = "u"
+→ exact match with alias "u" → alias-prefix mode ✅
+→ u.id, u.name, u.email, ... (alias columns first)
+→ CURRENT_TABLE priority ignored in this case
+```
+
+**Example in table editor context (CURRENT_TABLE = users, no alias):**
+```sql
+SELECT u|
+→ Context: SELECT_LIST without scope (no FROM/JOIN)
+→ Prefix: "u"
+→ users.id (CURRENT_TABLE column starting with 'u')
+→ users.name (CURRENT_TABLE column - shown for context)
+→ orders.user_id (DB-wide column starting with 'u' - allowed because no scope AND prefix exists)
+→ products.unit_price (DB-wide column starting with 'u')
+→ UPPER (function starting with 'u')
+→ UUID (function starting with 'u')
+→ UPDATE (keyword starting with 'u')
+```
+
+**Example in multi-query context (CURRENT_TABLE = users, second query has no scope):**
+```sql
+SELECT * FROM users u WHERE id = 1; SELECT u|
+→ Context: SELECT_LIST without scope (second query has no FROM/JOIN)
+→ Prefix: "u"
+→ users.id (CURRENT_TABLE column starting with 'u')
+→ users.name (CURRENT_TABLE column - shown for context)
+→ orders.user_id (DB-wide column starting with 'u' - allowed because no scope AND prefix exists)
+→ products.unit_price (DB-wide column starting with 'u')
+→ UPPER (function starting with 'u')
+→ UUID (function starting with 'u')
+→ UPDATE (keyword starting with 'u')
+```
+
+**Example in query with FROM:**
+```sql
+SELECT * FROM users WHERE u|
+→ Columns: (none - no columns start with 'u') (single table: unqualified)
+→ UPPER (function starting with 'u')
+→ UPDATE (keyword starting with 'u')
+→ (DB-wide columns excluded - WHERE is scope-restricted expression context)
+```
+
+**Example in query with JOIN (alias-exact-match mode):**
+```sql
+SELECT * FROM users u JOIN orders o WHERE u|
+→ Context: WHERE (scope-restricted)
+→ Prefix: "u"
+→ Alias-exact-match mode (u == alias 'u')
+→ u.id, u.name, u.email, u.password, u.is_enabled, u.created_at (all columns from alias 'u', multiple tables: qualified)
+→ UPPER, UUID, UNIX_TIMESTAMP (functions starting with 'u')
+→ (DB-wide columns excluded - WHERE is scope-restricted expression context)
+→ UPDATE (KEYWORD)
+```

+
+### Out-of-Scope Table Hints (SELECT_LIST with Scope)
+
+**Applies ONLY in SELECT_LIST when scope tables already exist (FROM/JOIN present).**
+
+**Purpose:** Keep SELECT scope-safe (no DB-wide columns), while still allowing controlled table discovery.
+
+---
+
+#### Trigger Conditions
+
+In SELECT_LIST with scope tables:
+
+If prefix P satisfies ALL of:
+- No alias-exact-match
+- No scope table startswith(P)
+- No scope column startswith(P)
+- BUT one or more physical tables in the database startswith(P)
+
+Then:
+- DO NOT suggest DB-wide columns
+- Instead, suggest each matching table as an individual hint item
+
+---
+
+#### Suggestion Format
+
+Each table is a separate suggestion item:
+
+```
+users + Add via FROM/JOIN
+customers + Add via FROM/JOIN
+```
+
+---
+
+#### Behavior Rules
+
+- Each table is a separate suggestion item
+- Suggestion kind: `TABLE_HINT_OUT_OF_SCOPE`
+- No column suggestions for out-of-scope tables
+- Selecting this item MUST NOT auto-insert JOIN type
+- **Minimal v1 behavior:**
+ - Either insert just the table name
+ - Or act as a non-insert hint (implementation choice)
+- JOIN type (INNER/LEFT/RIGHT) remains user decision
+- **No badges:** Badges are reserved for column data types (INT, VARCHAR, etc.)
+
+---
+
+#### Ordering (within SELECT_LIST with scope)
+
+1. Functions matching prefix
+2. Scope columns matching prefix
+3. Out-of-scope table hints
+4. Keywords
+
+**Important:** Functions MUST appear before table hints.
+
+**Rationale:** When typing `SELECT c| FROM orders`, the user most likely intends `COUNT, COALESCE, CONCAT`, not `customers` (new table). Therefore, functions are prioritized over discovery hints.
+
+---
+
+#### Example
+
+**Assume:**
+- Scope = [orders]
+- Database tables = [orders, users, customers]
+
+**Query:**
+```sql
+SELECT u| FROM orders
+```
+
+**Suggestions:**
+```
+→ UPPER
+→ UUID
+→ users + Add via FROM/JOIN
+→ UPDATE
+```
+
+**NOT suggested:**
+```
+❌ users.id
+❌ customers.name
+❌ any DB-wide columns
+```
+
+---
+
+#### Important Constraints
+
+- Applies ONLY to SELECT_LIST with existing scope
+- Does NOT apply to WHERE, JOIN_ON, GROUP_BY, HAVING, ORDER_BY
+- Does NOT apply when no scope exists (normal DB-wide allowed case)
+- Dot-completion behavior remains unchanged
+- Badges are reserved for column data types (INT, VARCHAR, etc.)
+

+
+## Context Rules Summary Matrix
+
+**In case of ambiguity, detailed context sections override this summary matrix.**
+
+This table provides a quick reference for implementers to understand the behavior of each context.
+
+| Context | Scope Required | DB-wide Columns | CURRENT_TABLE | Table Hints |
+|---------|---------------|-----------------|---------------|-------------|
+| **SELECT_LIST (no scope)** | No | Only with prefix | Yes (if set) | No |
+| **SELECT_LIST (with scope)** | Yes | No | Only if in scope | Yes (if prefix matches) |
+| **FROM_CLAUSE** | Scope building | N/A | Yes (if set, not present) | N/A |
+| **JOIN_CLAUSE** | Scope extension | N/A | Yes (if set, not present) | N/A |
+| **JOIN_ON** | Yes | No | Only if in scope | No |
+| **WHERE** | Yes | No | Only if in scope | No |
+| **ORDER_BY** | Yes | No | Only if in scope | No |
+| **GROUP_BY** | Yes | No | Only if in scope | No |
+| **HAVING** | Yes | No | Only if in scope | No |
+
+**Legend:**
+- **Scope Required:** Whether the context requires scope tables to exist
+- **DB-wide Columns:** Whether columns from tables outside scope can be suggested
+- **CURRENT_TABLE:** Whether CURRENT_TABLE columns can be suggested
+- **Table Hints:** Whether out-of-scope table hints can be suggested
+
+**Notes:**
+- SELECT_LIST without scope: DB-wide columns included only when prefix exists (guardrail against noise)
+- SELECT_LIST with scope: DB-wide columns excluded; Out-of-Scope Table Hints shown when prefix matches DB tables but no scope tables/columns
+- FROM_CLAUSE and JOIN_CLAUSE are table-selection contexts (scope building/extension), not column contexts
+- All scope-restricted expression contexts (JOIN_ON, WHERE, ORDER_BY, GROUP_BY, HAVING) follow the same rules (see **Scope-Restricted Expression Contexts** section)
+- Performance guardrail applies only to DB-wide columns group when no prefix (see Ordering Rules group 4)
+
+---
+
+## Implementation Notes
+
+- Context detection uses `sqlglot.parse_one()` with `ErrorLevel.IGNORE` for incomplete SQL
+- Dialect is retrieved from `CURRENT_CONNECTION.get_value().engine.value.dialect`
+- `CURRENT_TABLE` is an observable: `CURRENT_TABLE.get_value() -> Optional[SQLTable]`
+ - Used to prioritize columns from the current table when set
+ - Can be `None` if no table is currently selected
+- Fallback to regex-based context detection if sqlglot parsing fails
+
+---
+
+### Architecture Notes
+
+**Critical:** Centralize resolution logic to avoid duplication, but distinguish between table-selection and expression contexts.
+
+**Two distinct resolution functions are needed:**
+
+#### 1. Table Selection (FROM_CLAUSE, JOIN_CLAUSE)
+
+```python
+def resolve_tables_for_table_selection(
+ context: SQLContext,
+ scope: QueryScope,
+ current_table: Optional[SQLTable] = None,
+ prefix: Optional[str] = None
+) -> List[TableSuggestion]:
+ """
+ Resolve table candidates for FROM/JOIN clauses.
+
+ Returns tables in priority order:
+ 1. CTE names (if available from WITH clause)
+ 2. Physical tables from database
+ 3. CURRENT_TABLE (if set and not already present in current statement) - convenience shortcut
+
+ Filtering:
+ - If prefix provided, filter by startswith(prefix)
+ - Exclude tables already present in the current statement (query separated by separator)
+
+ Note: This is table-selection, not column resolution.
+ CURRENT_TABLE can appear even if scope tables already exist.
+ """
+ pass
+```
+
+#### 2. Expression Contexts (SELECT_LIST, WHERE, JOIN_ON, ORDER_BY, GROUP_BY, HAVING)
+
+```python
+def resolve_columns_for_expression(
+ context: SQLContext,
+ scope: QueryScope,
+ current_table: Optional[SQLTable] = None,
+ prefix: Optional[str] = None
+) -> List[ColumnSuggestion]:
+ """
+ Resolve columns for expression contexts with scope-aware restrictions.
+
+ Behavior depends on context and scope:
+
+ SCOPE-RESTRICTED contexts (WHERE, JOIN_ON, HAVING, ORDER_BY, GROUP_BY):
+ - See Scope-Restricted Expression Contexts section for complete rules
+ - Priority: FROM tables > JOIN tables
+
+ SELECT_LIST context:
+ - If NO scope tables:
+ * Include CURRENT_TABLE columns (if set)
+ * Include database-wide columns (only with prefix - guardrail against noise)
+ - If scope tables exist:
+ * CURRENT_TABLE included only if in scope; otherwise ignored
+ * Include scope table columns
+ * Database-wide columns EXCLUDED (scope restriction active)
+ * Exception: Out-of-Scope Table Hints if prefix matches DB tables but no scope columns
+
+ All columns use alias.column format when alias exists, otherwise table.column.
+ """
+ pass
+```
+
+**Benefits:**
+- Clear separation between table-selection and expression contexts
+- Enforces scope restriction rules consistently
+- Single source of truth for each context type
+- Easier to test and maintain
+- Avoids logic duplication
+
+**Architectural improvement (optional):**
+
+For cleaner architecture, consider using a `QueryScope` object instead of passing multiple parameters:
+
+```python
+@dataclass
+class QueryScope:
+ from_tables: List[TableReference]
+ join_tables: List[TableReference]
+ derived_tables: List[DerivedTable]
+ ctes: List[CTE]
+ current_table: Optional[SQLTable]
+ aliases: Dict[str, TableReference] # alias -> table mapping
+
+def resolve_columns_in_scope(
+ scope: QueryScope,
+ prefix: Optional[str] = None
+) -> List[ColumnSuggestion]:
+ """Pure function - no global context dependency."""
+ pass
+```
+
+This makes the function pure and easier to test.
+
+---
+
+**Tables in Scope Definition (with CTEs and Derived Tables):**
+
+With CTEs and subquery aliases, "tables in scope" is not just physical tables from FROM/JOIN. The priority order is:
+
+```
+tables_in_scope = [
+ 1. Derived tables (subquery alias) in FROM/JOIN
+ 2. CTEs referenced in FROM/JOIN
+ 3. Physical tables in FROM/JOIN
+]
+```
+
+**Column resolution follows this order:**
+
+**Important:** Include CURRENT_TABLE columns only when allowed by context rules:
+- SELECT_LIST with no scope tables, OR
+- CURRENT_TABLE is in scope (present in FROM/JOIN)
+
+Otherwise omit CURRENT_TABLE entirely.
+
+1. **CURRENT_TABLE columns** (if allowed by context rules) - use alias if table has alias in query
+2. **Derived table columns** - use alias (only sensible name)
+3. **CTE columns** - use CTE name (acts as alias)
+4. **Physical table columns from FROM** - use alias if defined
+5. **Physical table columns from JOIN** - use alias if defined
+6. **Database columns** (all other tables, with guardrail - only in SELECT_LIST or when no scope restriction)
+
+**Example:**
+```sql
+WITH active_users AS (SELECT id, name FROM users WHERE status = 'active')
+SELECT * FROM (SELECT id, total FROM orders) AS o
+JOIN active_users au ON o.id = au.id
+WHERE |
+→ o.id, o.total (derived table, priority 2)
+→ au.id, au.name (CTE, priority 3)
+→ (no physical tables in this query)
+```
+
+**Note:** Alias-first is fundamental here - for derived tables and CTEs, the alias/CTE name is often the **only** sensible name (no underlying physical table name).
+
+### Scope Handling (Subqueries and CTEs)
+
+**Important:** Scope handling for subqueries and CTEs.
+
+**v1 subquery scope resolution:**
+- **v1 supports inner scope when cursor is inside parentheses of a subquery** (sqlglot typically handles this correctly)
+- Fallback to outer scope only when parsing/cursor mapping fails
+- When subquery has FROM clause, suggest columns from subquery scope (inner scope)
+- When cursor is outside subquery parentheses, suggest columns from outer scope
+
+**Examples:**
+```sql
+-- Cursor outside subquery: outer query scope
+SELECT * FROM users WHERE id IN (SELECT user_id FROM orders) AND |
+→ Suggests columns from 'users' (outer query scope)
+
+-- Cursor inside subquery: inner query scope (v1 supported)
+SELECT * FROM users WHERE id IN (SELECT | FROM orders)
+→ Suggests columns from 'orders' (inner query scope - subquery has FROM)
+
+-- Cursor inside subquery WHERE: inner query scope (v1 supported)
+SELECT * FROM users WHERE id IN (SELECT user_id FROM orders WHERE |)
+→ Suggests columns from 'orders' (inner query scope)
+```
+
+**CTE Support (WITH clauses):**
+
+CTEs are increasingly common and should be considered for v1 implementation:
+
+```sql
+WITH active_users AS (SELECT * FROM users WHERE status = 'active')
+SELECT * FROM active_users WHERE |
+→ active_users.id, active_users.name, ... (CTE columns)
+```
+
+**Basic CTE support:**
+- Treat CTEs as available tables in the query scope
+- CTE name acts like a table name in FROM/JOIN contexts
+- Columns from CTE should be resolved (if CTE definition is parseable)
+- **CTE visibility is limited to the statement where they are defined (standard SQL behavior)**
+
+**CTE scope and visibility:**
+
+CTEs follow **standard SQL semantics**: a CTE is visible only within the statement where it is defined. This is the behavior mandated by the SQL standard and implemented by all major databases.
+
+**Example - CTE scope (standard SQL):**
+```sql
+WITH a AS (...)
+SELECT * FROM a;
+SELECT * FROM |
+→ CTE 'a' is NOT visible here (different statement, separated by `;`)
+→ Show only physical tables
+```
+
+**Vendor-specific extensions:**
+
+Some databases offer non-standard CTE extensions (e.g., session-scoped CTEs, persistent CTEs). These are **NOT supported in v1**. The autocomplete system follows standard SQL semantics only.
+
+**Advanced CTE features (future enhancement):**
+- Recursive CTEs (standard SQL, but complex parsing)
+- Multiple CTEs with dependencies (standard SQL)
+- CTE column aliasing (standard SQL)
+
+**Subquery Aliases (Derived Tables):**
+
+Subqueries with aliases (derived tables) should also be considered for v1:
+
+```sql
+SELECT * FROM (SELECT id, name FROM users) AS u WHERE |
+→ u.id, u.name (derived table columns)
+```
+
+**Basic support:**
+- Treat aliased subquery as a table in scope
+- Resolve columns from the subquery SELECT list (if parseable)
+- Alias acts like a table name
+
+**Note:** This is similar to CTE support but inline. If CTEs are supported, derived tables should follow the same pattern.
+
+**Window Functions (Future Enhancement):**
+
+Window functions with OVER clause are common in modern SQL:
+
+```sql
+SELECT *, ROW_NUMBER() OVER |
+→ (PARTITION BY, ORDER BY)
+
+SELECT *, ROW_NUMBER() OVER (PARTITION BY |
+→ Columns in scope (qualified, alias-first)
+
+SELECT *, ROW_NUMBER() OVER (PARTITION BY status ORDER BY |
+→ Columns in scope (qualified, alias-first)
+```
+
+**Future support:**
+- Detect OVER clause context
+- After `OVER (` suggest keywords: `PARTITION BY`, `ORDER BY`
+- After `PARTITION BY` suggest columns in scope
+- After `ORDER BY` suggest columns in scope + `ASC`, `DESC`
+
+**Note:** This is a specialized context that can be added after core functionality is stable.
+
+---
+
+### Potential Challenges
+
+**sqlglot Parsing of Incomplete SQL:**
+
+Test thoroughly with partial queries. You might need a hybrid approach that falls back to regex faster than expected.
+
+**Examples of challenging cases:**
+```sql
+SELECT id, name FROM users WHERE |
+→ sqlglot may parse successfully
+
+SELECT id, name FROM users WH|
+→ sqlglot may fail, need regex fallback
+
+SELECT * FROM users WHERE status = '|
+→ Incomplete string, sqlglot may fail
+```
+
+**Recommendation:**
+- Use `sqlglot.parse_one()` with `ErrorLevel.IGNORE` as primary approach
+- Implement robust regex fallback for common patterns
+- Test with many incomplete query variations
+- Log parsing failures to identify patterns that need special handling
+
+**Fallback trigger rule:**
+- If sqlglot does not produce a useful AST → fallback to regex
+- If cursor position cannot be mapped to an AST node → fallback to regex
+- Log: `(dialect, snippet_around_cursor, reason)` for building golden test cases
+
+**Example logging:**
+```python
+if not ast or not can_map_cursor_to_node(ast, cursor_pos):
+ logger.debug(
+ "sqlglot_fallback",
+ dialect=dialect,
+ snippet=text[max(0, cursor_pos-50):cursor_pos+50],
+ reason="no_useful_ast" if not ast else "cursor_mapping_failed"
+ )
+ return regex_based_context_detection(text, cursor_pos)
+```
+
+**Benefit:** Build real-world golden tests from production edge cases
+
+**Cursor Position Context:**
+
+Make sure context detection knows exactly where the cursor is, not just what's before it.
+
+**Critical distinction:**
+```sql
+SELECT | FROM users
+→ Context: SELECT_LIST (before FROM)
+→ Show: columns, functions
+
+SELECT id| FROM users
+→ Context: After column name (before FROM)
+→ Show: FROM, AS, etc. (comma is never suggested)
+```
+
+**Implementation note:**
+- Extract text before cursor: `text[:cursor_pos]`
+- Extract text after cursor: `text[cursor_pos:]` (for context validation)
+- Check if cursor is immediately after a complete token vs in the middle
+- Use both left and right context for accurate detection
+
+---
+
+### Performance Optimization
+
+**Large Schemas:**
+
+The 400-item guardrail is good, but additional optimizations are recommended:
+
+**Debouncing:**
+- Delay autocomplete trigger by 150-300ms after last keystroke
+- Avoids excessive computation while user is typing rapidly
+- Cancel pending autocomplete requests if new input arrives
+
+**Caching:**
+- Cache database schema (tables, columns) in memory
+- Refresh only when schema changes (DDL operations detected)
+- Cache parsed query structure for current statement
+- Invalidate cache when query changes significantly
+
+**Schema cache invalidation triggers:**
+- DDL operations: `CREATE`, `ALTER`, `DROP`, `TRUNCATE`
+- Database/schema change (e.g., `USE database`)
+- Manual refresh (user-triggered)
+- Reconnection to database
+- **Best-effort approach:** Some engines (e.g., PostgreSQL) support event listeners for schema changes; if not available, invalidate on DDL keyword detection or periodic refresh
+
+**Lazy Loading:**
+- Load column details only when needed (not all upfront)
+- For large tables (>100 columns), load columns on-demand
+- Consider pagination for very large suggestion lists
+
+**Example implementation:**
+```python
+class AutocompleteCache:
+ def __init__(self):
+ self._schema_cache = {} # {database: {table: [columns]}}
+ self._last_query_hash = None
+ self._parsed_query_cache = None
+
+ def get_columns(self, table: str) -> List[Column]:
+ if table not in self._schema_cache:
+ self._schema_cache[table] = fetch_columns(table)
+ return self._schema_cache[table]
+
+ def invalidate_schema(self):
+ self._schema_cache.clear()
+```
+
+---
+
+### Statement Separator
+
+The statement separator is NOT hardcoded.
+
+It is determined at runtime using:
+
+```
+effective_separator = user_override or engine_default
+```
+
+**Separator types:**
+
+1. **Single-character separators** (most engines):
+ - MySQL, MariaDB, PostgreSQL, SQLite: `";"`
+ - User can override with any single character
+
+2. **Multi-character token separators** (SQL Server and similar):
+ - SQL Server: `"GO"` (case-insensitive keyword)
+ - Must be a standalone token (word boundary required)
+ - Example: `SELECT * FROM users GO SELECT * FROM orders` (valid)
+ - Example: `SELECT * FROM users_GO SELECT * FROM orders` (invalid - no word boundary)
+
+**Validation:**
+
+1. **Trim whitespace** from `user_override` before validation
+2. **Single-character override:** If length == 1 after trimming → valid
+3. **Multi-character override:** If length >= 2 after trimming:
+ - **Valid:** ONLY if alphanumeric + underscore `[A-Za-z0-9_]+`
+ - **Invalid:** If contains symbols (e.g., `//`, `$$`, `GO;`) → reject, fallback to `engine_default`
+4. **Invalid override:** If validation fails → ignore override and fallback to `engine_default`
+
+**Valid override examples:**
+- `"GO"` → valid (alphanumeric)
+- `"BEGIN"` → valid (alphanumeric)
+- `";"` → valid (single char)
+- `"END_BLOCK"` → valid (alphanumeric + underscore)
+
+**Invalid override examples (rejected, use engine_default):**
+- `"//"` → invalid (symbols only)
+- `"GO;"` → invalid (mixed alphanumeric + symbol)
+- `"$$"` → invalid (symbols only)
+- `"GO "` → invalid after trim (contains space before trim)
+
+**Implementation notes:**
+
+- **Single-character separators:** Simple string split with string/comment awareness
+- **Multi-character token separators:** Require word boundary detection using regex `\b{separator}\b`
+ - Example: `\bGO\b` for SQL Server
+ - Word boundary `\b` works correctly because multi-char separators are restricted to `[A-Za-z0-9_]+`
+- **Both types MUST respect:**
+ - String literals: `'...'`, `"..."`, `` `...` ``
+ - Comments: `-- ...`, `/* ... */`
+ - Dollar-quoted strings (PostgreSQL): `$$...$$`, `$tag$...$tag$`
+
+All multi-query splitting logic MUST use the effective separator.
+Hardcoding `";"` is forbidden.
+
+---
+
+### Multi-Query Support
+
+**Important:** When multiple queries are present in the editor (separated by the effective statement separator), context detection must operate on the **current query** (where the cursor is), not the entire buffer.
+
+**Implementation approach:**
+1. Find statement boundaries by detecting the effective separator
+2. Extract the query containing the cursor position
+3. Run context detection only on that query
+
+**Edge cases:**
+- If cursor is on the separator, treat it as "end of previous statement".
+- Empty statements are ignored (no context); fallback to EMPTY.
+- For token separators (e.g., GO), cursor on the token itself is treated as "end of previous statement"
+
+**Examples:**
+
+**Single-character separator (`;`):**
+```sql
+SELECT * FROM users WHERE id = 1;
+SELECT * FROM orders WHERE | ← cursor here
+SELECT * FROM products;
+```
+Context detection should analyze only: `SELECT * FROM orders WHERE |`
+
+**Token separator (`GO` for SQL Server):**
+```sql
+SELECT * FROM users WHERE id = 1
+GO
+SELECT * FROM orders WHERE | ← cursor here
+GO
+SELECT * FROM products
+```
+Context detection should analyze only: `SELECT * FROM orders WHERE |`
+
+**Critical:**
+- Do NOT use simple `text.split(effective_separator)`
+- The separator must be ignored inside:
+ - Strings (`'...'`, `"..."`)
+ - Comments (`--`, `/* */`)
+ - Dollar-quoted strings (PostgreSQL: `$$...$$`)
+- For token separators, word boundaries MUST be respected (e.g., `users_GO` is NOT a separator)
+
+**Recommended approach:**
+- Use sqlglot lexer/tokenizer to find statement boundaries (handles strings/comments correctly)
+- For token separators: use regex with word boundaries (e.g., `\bGO\b` case-insensitive)
+- Or implement robust separator detection with string/comment awareness
+
+### Multi-Word Keywords
+
+Multi-word keywords (e.g., `ORDER BY`, `GROUP BY`, `IS NULL`, `IS NOT NULL`, `NULLS FIRST`) are suggested as a single completion item but inserted verbatim.
+
+**Matching rule:** Use `startswith()` on normalized text (single spaces, case-insensitive). Normalize both the user input and the keyword before matching.
+
+**Examples:**
+- User types `ORDE|` → normalized input: `"orde"` → matches `ORDER BY` (normalized: `"order by"`) ✅
+- User types `ORDER B|` → normalized input: `"order b"` → matches `ORDER BY` (normalized: `"order by"`) ✅
+- User types `NULLS L|` → normalized input: `"nulls l"` → matches `NULLS LAST` (normalized: `"nulls last"`) ✅
+- User types `IS N|` → normalized input: `"is n"` → matches `IS NULL`, `IS NOT NULL` ✅
+
+---
+
+## Edge Cases
+
+This section documents problematic scenarios and their explicit resolutions.
+
+### 1. Cursor on Separator
+
+**Scenario:** Cursor is positioned exactly on the statement separator.
+
+```sql
+SELECT * FROM users;|
+SELECT * FROM orders;
+```
+
+**Resolution:** Treat as "end of previous statement". Context detection operates on the first statement (`SELECT * FROM users`), suggesting clause keywords like `WHERE`, `ORDER BY`, `LIMIT`.
+
+---
+
+### 2. Empty Statement
+
+**Scenario:** Multiple separators with no content between them.
+
+```sql
+SELECT * FROM users;;|
+```
+
+**Resolution:** Empty statements are ignored. Fallback to EMPTY context, suggesting primary keywords (`SELECT`, `INSERT`, `UPDATE`, etc.).
+
+---
+
+### 3. Incomplete String Literal
+
+**Scenario:** Cursor inside an unclosed string.
+
+```sql
+SELECT * FROM users WHERE name = '|
+```
+
+**Resolution:** sqlglot parsing may fail. Fallback to regex-based context detection. Suggest literal keywords (`NULL`, `TRUE`, `FALSE`) and allow user to complete the string.
+
+---
+
+### 4. Separator Inside String/Comment
+
+**Scenario:** Statement separator appears inside a string or comment.
+
+```sql
+SELECT * FROM users WHERE note = 'Price: $10; Discount: 20%' AND |
+```
+
+**Resolution:** The `;` inside the string MUST be ignored. Use sqlglot lexer/tokenizer or implement string/comment-aware separator detection. Context: WHERE clause.
+
+---
+
+### 5. Ambiguous Alias with Multiple Matches
+
+**Scenario:** Prefix could match multiple aliases if using `startswith`.
+
+```sql
+SELECT * FROM users u JOIN user_stats us WHERE u|
+```
+
+**Resolution:** Use **exact match** rule. `"u" == "u"` → alias-prefix mode for `u`. If user types `us|`, then `"us" == "us"` → alias-prefix mode for `us`. No ambiguity.
+
+---
+
+### 6. CURRENT_TABLE Not in Scope
+
+**Scenario:** CURRENT_TABLE is set in UI, but not present in query scope.
+
+```sql
+-- CURRENT_TABLE = users (in table editor)
+SELECT * FROM orders WHERE |
+```
+
+**Resolution:** CURRENT_TABLE columns MUST NOT be suggested. Only `orders.*` columns are valid (scope restriction active). CURRENT_TABLE is ignored unless it appears in FROM/JOIN.
+
+---
+
+### 7. Table Name Matches Column Name
+
+**Scenario:** Prefix matches both a table name and column names.
+
+```sql
+SELECT u| FROM orders
+```
+
+**Resolution:** Context is SELECT_LIST with scope (orders in FROM). Apply scope-restricted prefix matching:
+- Column-name matching: `orders.user_id` (scope table column starting with 'u')
+- Functions: `UPPER`, `UUID`, `UNIX_TIMESTAMP`
+- Out-of-Scope Table Hint: `users + Add via FROM/JOIN` (prefix matches DB table not in scope)
+- ❌ DB-wide columns excluded (scope restriction active - no `users.*` expansion)
+
+---
+
+### 8. Dot-Completion on Non-Existent Table
+
+**Scenario:** User types dot after a non-existent table/alias.
+
+```sql
+SELECT * FROM users WHERE xyz.|
+```
+
+**Resolution:** `xyz` is not a valid table or alias in scope. Return empty suggestions. Optionally show error hint: "Table or alias 'xyz' not found".
+
+---
+
+### 9. Multi-Query with Different Separators
+
+**Scenario:** User has overridden separator, but buffer contains old separator.
+
+```sql
+-- effective_separator = "GO"
+SELECT * FROM users;
+GO
+SELECT * FROM orders WHERE |
+```
+
+**Resolution:** Only the effective separator (`GO`) is recognized. The `;` is treated as part of the first statement (not a separator). Context detection operates on the second statement.
+
+---
+
+### 10. CTE Referenced Before Definition
+
+**Scenario:** User references CTE before defining it (incomplete query).
+
+```sql
+SELECT * FROM active_users WHERE |
+WITH active_users AS (SELECT * FROM users WHERE status = 'active')
+```
+
+**Resolution:** sqlglot parsing may fail or produce incorrect AST. Fallback to regex-based context detection. CTE `active_users` is not recognized (defined after usage). Treat as physical table or show error hint.
+
+---
+
+### 11. Nested Subquery Context
+
+**Scenario A:** Cursor in SELECT list of subquery (subquery has FROM).
+
+```sql
+SELECT * FROM users WHERE id IN (SELECT | FROM orders)
+```
+
+**Resolution:** **v1 supported**. Context detection recognizes the subquery scope (cursor inside parentheses). Suggest `orders.*` columns (inner scope). The subquery's FROM clause establishes scope.
+
+**Scenario B:** Cursor in WHERE clause of subquery.
+
+```sql
+SELECT * FROM users WHERE id IN (SELECT user_id FROM orders WHERE |)
+```
+
+**Resolution:** **v1 supported**. Context detection operates on the subquery scope (cursor inside parentheses). Suggest `orders.*` columns (inner scope). The subquery's FROM clause establishes scope.
+
+**Scenario C:** Cursor in subquery without FROM (correlated subquery).
+
+```sql
+SELECT * FROM users WHERE id IN (SELECT | WHERE status = 'active')
+```
+
+**Resolution:** No FROM in subquery → no inner scope established. Fallback to outer scope (`users.*`) or show error depending on parsing success. This is acceptable behavior for v1.
+
+**Note:** This scenario is **extremely rare** in practice. The vast majority of correlated subqueries still have a table in the FROM clause (e.g., `SELECT user_id FROM orders WHERE orders.user_id = users.id`). Subqueries without FROM are edge cases, making the v1 behavior entirely reasonable.
+
+---
+
+### 12. Column Name Equals Keyword
+
+**Scenario:** Table has a column named after a SQL keyword.
+
+```sql
+-- Table: users (columns: id, name, select, from)
+SELECT * FROM users WHERE |
+```
+
+**Resolution:** Suggest all columns including `users.select` and `users.from`. Column names take precedence over keywords in expression contexts. User must quote if necessary (e.g., `` `select` `` in MySQL).
+
+---
+
+### 13. Alias Shadows Table Name
+
+**Scenario:** Alias has the same name as another table.
+
+```sql
+SELECT * FROM users AS orders WHERE |
+```
+
+**Resolution:** Alias `orders` shadows the physical table `orders`. Suggest `orders.id, orders.name, ...` (columns from `users` table via alias `orders`). Physical table `orders` is not in scope.
+
+---
+
+### 14. Self-Join with Same Table
+
+**Scenario:** Table joined with itself using different aliases.
+
+```sql
+SELECT * FROM users u1 JOIN users u2 ON u1.id = u2.manager_id WHERE |
+```
+
+**Resolution:** Suggest columns from both aliases:
+- `u1.id, u1.name, u1.email, ...` (first instance)
+- `u2.id, u2.name, u2.email, ...` (second instance)
+
+Both are in scope. No deduplication (different aliases = different logical tables).
+
+---
+
+### 15. Whitespace-Only Prefix
+
+**Scenario:** User types only whitespace after a keyword.
+
+```sql
+SELECT |
+```
+
+**Resolution:** Whitespace is trimmed. No prefix exists. Show all columns (if scope exists) + functions + keywords.
+
+---
+
+## Spacing After Completion
+
+- **Keywords:** Space added after keywords (e.g., `SELECT `, `FROM `, `WHERE `, `JOIN `, `AS `)
+ - Multi-word keywords are treated as keywords for spacing (space appended after `ORDER BY`, `GROUP BY`, `IS NULL`, etc.)
+- **Columns:** No space added (e.g., `users.id|` allows immediate `,` or space)
+- **Tables:** No space added (e.g., `users|` allows immediate space or alias)
+- **Functions:** No space added by default
+ - **Future enhancement:** Consider function snippets with cursor positioning (e.g., `COUNT(|)` where `|` is cursor position)
+ - This would require snippet support in the autocomplete system

+# PeterSQL Themes
+
+This directory contains theme files for PeterSQL. Each theme defines colors for the editor and autocomplete components, with support for both dark and light modes.
+
+## Theme Structure
+
+Each theme is a YAML file with the following structure:
+
+```yaml
+name: Theme Name
+version: 1.0
+
+editor:
+ dark:
+ # Colors for dark mode
+ background: auto # 'auto' uses system color
+ foreground: auto
+ keyword: '#569cd6'
+ string: '#ce9178'
+ # ... more colors
+
+ light:
+ # Colors for light mode
+ background: auto
+ foreground: auto
+ keyword: '#0000ff'
+ # ... more colors
+
+autocomplete:
+ dark:
+ keyword: '#569cd6'
+ function: '#dcdcaa'
+ table: '#4ec9b0'
+ column: '#9cdcfe'
+
+ light:
+ keyword: '#0000ff'
+ function: '#800080'
+ table: '#008000'
+ column: '#000000'
+```
+
+## Available Colors
+
+### Editor Colors
+- `background` - Editor background
+- `foreground` - Default text color
+- `line_number_background` - Line number margin background
+- `line_number_foreground` - Line number text color
+- `keyword` - SQL keywords (SELECT, FROM, etc.)
+- `string` - String literals
+- `comment` - Comments
+- `number` - Numeric literals
+- `operator` - Operators (+, -, *, etc.)
+- `property` - JSON properties
+- `error` - Error highlighting
+- `uri` - URI/URL highlighting
+- `reference` - Reference highlighting
+- `document` - Document markers
+
+### Autocomplete Colors
+- `keyword` - SQL keywords
+- `function` - SQL functions
+- `table` - Table names
+- `column` - Column names
+
+## Using 'auto' Color
+
+Set a color to `auto` to use the system color. This is useful for background and foreground colors to ensure the editor adapts to the system theme.
+
+## Creating a New Theme
+
+1. Create a new YAML file in this directory (e.g., `mytheme.yml`)
+2. Copy the structure from `petersql.yml`
+3. Customize the colors
+4. Update `settings.yml` to use your theme:
+ ```yaml
+ theme:
+ current: mytheme
+ ```
+
+## Default Theme
+
+The default theme is `petersql.yml`, which provides VS Code-like colors for both dark and light modes.
