SQL Mocker is a web app that creates SQL from natural-language questions using a reviewed copy of database schema metadata. Users can provide schema information by uploading a file, pasting metadata, building it manually, or supplying results from an extraction script run in their own database. Its workspace can detect, review, edit, or add table relationships, including ones missing from the original metadata. Existing SQL can be submitted for explanation, review, improvement, formatting, conversion, troubleshooting, or mapping output columns and joins. The app can generate dummy data from a schema to preview results and query logic without using production rows. Its homepage lists 17 supported database systems, including SQL Server, PostgreSQL, MySQL, Snowflake, BigQuery, and MongoDB. SQL Mocker says schema-based generation does not require database credentials and does not connect to a live customer database. It presents SQL for review and copying; users run queries themselves. The free Explore plan includes 50 AI queries total and five saved projects. Paid plan listings are marked as coming soon. The maker advises reviewing and validating AI-generated SQL before use.
