SQL Practice Playground

Choose an exercise or write a query against the sample schema. Run a single SELECT or WITH statement, inspect the results, and download them.

What to know

The sql.js SQLite engine loads from a pinned CDN on first use; an internet connection is required to load it. Query text stays in the browser. The sample database resets for every run and is read-only. Results are capped at 1,000 rows, and long queries can be cancelled or stopped after 15 seconds. Syntax is SQLite, not T-SQL.
