- Add INTERSECT and EXCEPT to queryNoWith rule for set operations - Remove 173 unused KW_* lexer rules for removed features (views, indexes, grants, transactions, stored procedures, window functions, triggers, etc.) - Trim nonReserved list to only keywords actually used in parser rules - Remove unused UNICODE_STRING and DIGIT_IDENTIFIER lexer rules - Keyword count reduced from 263 to 90 (close to ~100 target) - All 197 test suites pass (5627 tests)
- Remove core structural keywords from nonReserved so they cannot be used as identifiers: SELECT, FROM, WHERE, CREATE, TABLE, INSERT, UPDATE, DELETE, DROP, ALTER, SET, JOIN, GROUP, HAVING, ORDER, ON, UNION, INTERSECT, EXCEPT, INTO, NOT, AND, OR, IN, BETWEEN, LIKE, IS, EXISTS, CASE, WHEN, THEN, ELSE, END, CAST, AS, DISTINCT, PRIMARY, CONSTRAINT, REFERENCES, COLUMN, UNIQUE, CHECK, FOREIGN, RENAME, RECURSIVE, WITH, NULL, ESCAPE, NULLIF - Add DIGIT_IDENTIFIER lexer token for identifiers starting with a digit (e.g. 123abc, 1st_column) - Include DIGIT_IDENTIFIER in identifier rule alternatives
…tion - Add GenericSqlListener and GenericSqlVisitor exports to src/index.ts - Add GenericSQLOptions interface with configurable diagnostics flag - Override validate() to return empty array when diagnostics disabled - Export GenericSQLOptions type from src/index.ts
- Add exitQuerySpecification for QUERY_RESULT entity tracking - Add exitSelectItem for column entity collection in SELECT clauses - Track wildcard columns (ColumnDeclareType.ALL) for * and table.* - Track expression columns with alias support (ColumnDeclareType.EXPRESSION) - Stage previously untracked files (errorListener, splitListener, semanticContextCollector)
