SQL Playground FAQ

  
How should I use this?
Choose a dataset, run SQL, inspect results or query plans, then copy the review brief or export output for practice and QA.
What should I verify?
Check the selected dataset, mutating-query warning, result row count, explain plan, challenge feedback and exported files.
Is this connected to a live database?
No. It runs SQLite locally in your browser against bundled or imported data.
