Frequently Asked Questions
Is the SQL query generator free?
Yes. The AI SQL generator is completely free and requires no signup. To keep it free for everyone, there is a fair-use limit of a few queries per minute per user.
Which SQL dialects are supported?
PostgreSQL, MySQL, SQLite, SQL Server (T-SQL), Oracle, Google BigQuery and Snowflake. The generator adapts syntax — LIMIT vs TOP, date functions, and quoting — to the dialect you choose.
Should I paste my database schema?
It’s optional but recommended. Pasting your table and column names (or CREATE TABLE statements) lets the AI use your exact schema instead of guessing table names. Never paste real credentials or sensitive data.
Should I review the generated SQL before running it?
Always. AI-generated SQL is a strong starting point, but review it — especially UPDATE and DELETE statements — and test against a non-production database first.
