MySQL SQL Validator

The tool validates MySQL SQL statements for syntax and structure without contacting a database. It accepts a query_text string and a dialect setting (MySQL) and returns a structured report of syntax errors, including line and column locations. It is designed for developers, DBAs, and CI engineers who need fast, non-executing validation to catch mistakes before deployment or data migration.
It performs lexical analysis and parsing against a MySQL grammar, then applies a lint-like pass to identify common pitfalls such as missing semicolons, unbalanced parentheses, misquoted identifiers, and unsupported constructs. Optional settings enable multi-statement validation, strict parsing, and ignoring comments to mirror real-world coding styles.
Output includes is_valid and a list of errors with line, column, and message fields, plus optional warnings and a parsed summary. This enables precise debugging and easier CI integration, as teams can fail builds on syntax violations or warn on stylistic issues while preserving safe test environments.
Unique value comes from MySQL-specific handling (backtick identifiers, relevant keywords, and routine syntax), clear error localization, and the ability to validate large scripts quickly without execution. Use cases include pre-commit checks, migration script validation, learning environments, and QA validation across development pipelines.
