SQLite Validator

The sqlite online validator checks input SQL against SQLite grammar, reporting syntax errors with line and column. It is designed for developers, DBAs, students, and educators who need quick feedback without a local database. It supports standard SQLite constructs such as SELECT, INSERT, UPDATE, DELETE, CREATE, VIEW, TRIGGER, and WITH clauses.
Conceptually, the tool performs lexical analysis, parses tokens, builds a parse tree, and validates syntax without executing statements. It highlights the first error and returns a descriptive message, the location, and a canonical form when requested. It also handles comments and batches of statements.
Outputs include a status flag, error details, and an optional normalized version of the input. Use cases include rapid syntax checks during coding sessions, education, and pre-commit validation in lightweight workflows. The service is stateless and does not access or modify any database.
Unique value lies in tight SQLite dialect adherence, precise error reporting, no data mutation, and easy integration into tooling pipelines. It serves solo developers and teams building apps with embedded databases.
