About this tool

Provide your schema (or describe your tables) plus a natural-language question, and Gemini will produce the SQL query with an explanation.

Every request is sent server-side to the Gemini 2.5 Flash model with a task-specific system prompt tuned for database work. Your input is not persisted on our servers — we only keep an anonymised metric (task, input length, latency) so we can improve the tool.

Combine this with our other AI developer tools and privacy-first developer utilities to move faster in your day-to-day work.

FAQ

Which SQL dialects are supported?

Standard SQL by default. Mention Postgres, MySQL, SQL Server, SQLite, BigQuery or Snowflake in your request for dialect-specific features.

Do I need to provide the schema?

It is strongly recommended. Either paste your DDL or list the tables and columns. Without a schema the AI will make reasonable assumptions and note them.

Can it write JOINs, CTEs and window functions?

Yes — for complex analytical queries Gemini will use CTEs, window functions and subqueries where appropriate.

Is it safe to run the generated SQL directly?

Always review generated SQL against your schema and test on a non-production database first. This tool assists, it does not replace review.
