What is a SQL Validator?

A SQL Validator checks whether a SQL query is syntactically valid and highlights issues that prevent execution. SQLAI.ai also helps correct those syntax errors.

Who is this SQL Syntax Checker intended for?

It is intended for developers, analysts, analytics engineers, DBAs, and SQL learners who need fast query validation before running SQL in apps, pipelines, or dashboards.

What are common use cases for fix sql workflows?

Common use cases include debugging failing API queries, fixing dashboard SQL before publishing, validating migration scripts, and correcting legacy SQL during refactors.

Can I validate different SQL dialects?

Yes. SQLAI.ai supports major SQL and analytics engines so you can run SQL syntax validation across multiple dialects from one workflow.

Does it only show errors or also fix sql queries?

It does both. You get inline syntax errors, detailed explanations, and a corrected SQL version you can review and validate again.

Can I compare the original and corrected SQL?

Yes. SQLAI.ai includes a side-by-side SQL diff so you can inspect every exact query change before execution or handoff.
