Questions
Can this test real database queries?
It tests query logic against a temporary local SQLite database. It does not connect to MySQL, PostgreSQL, or production databases.
What SQL statements can I try?
The local engine supports common SQLite statements such as CREATE TABLE, INSERT, SELECT, JOIN, WHERE, GROUP BY, ORDER BY, and aggregate functions.
Is my query uploaded?
No. The SQL engine loads in your browser and runs the query locally.
Does Utilumo upload my input?
No. This tool is designed for local browser processing and does not send your input to a server.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
