TiDB Parser Module

TiDB-backed parser adapter for multi-statement SQL parsing and parser-warning collection.

Files

File Responsibility
parser.go Parses SQL text and preserves raw statement nodes plus parser warnings
extractor.go Wraps TiDB AST nodes in parser-neutral extractors and performs TiDB-specific statement extraction including database/schema lifecycle DDL (CREATE/DROP DATABASE/SCHEMA normalized to create_schema/drop_schema with ObjectType="database")
parser_test.go Verifies multi-statement parsing, parse-failure behavior, and extractor-backed wrapping

Overview

Package tidbparser extracts parser-neutral statements from TiDB AST nodes. input: TiDB parser statement nodes and parser-neutral dialect metadata output: extractor-backed parsed statements for the application layer pos: infrastructure extraction adapter between TiDB AST and domain spec note: if this file changes, update this header and module README.md.

Package tidbparser loads SQL text through the TiDB parser. input: SQL text and TiDB parser runtime dependencies output: raw parsed statement nodes and parser warnings for application orchestration pos: infrastructure parser adapter for MySQL and TiDB SQL parsing note: if this file changes, update this header and module README.md.
