1. What is the SQL Query Builder?

Write correct SQL faster. Pick the query type, table and columns, add conditions and sorting, and copy a clean query for MySQL, PostgreSQL or SQLite. For CREATE TABLE, sensible column types are suggested when you leave them out. Always review queries before running them on real data — especially UPDATE and DELETE.

Your text never leaves your device — The tool runs entirely in your browser using JavaScript. Nothing is uploaded, so you can paste private documents without worry. That also means there is no account to create and no file to upload.
It works on your phone too — Open the tool in any modern browser on Android or iPhone. The layout adjusts to the screen and everything works the same way on a small screen as on a desktop.
