Questions
Does SQL Playground connect to a database?
No. It creates a temporary SQLite database in your browser for each run. Nothing is sent to a server.
Can I test JOIN and GROUP BY queries?
Yes. The starter databases include related tables so you can test SELECT, JOIN, WHERE, GROUP BY, ORDER BY, and aggregate queries.
Is this SQLite or PostgreSQL?
The first version runs SQLite in the browser. It is ideal for learning SQL, testing query shape, and building examples without a database account.
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.
