SQL Playground

Practice SQL directly in your browser with no installation required. The tutorial database is loaded into browser memory, so you can write queries and see results instantly.

How to Use

  1. Table List — Expand "Tables" at the top to see available tables and row counts. Click a table to auto-fill a SELECT query.
  2. Write SQL — Type your SQL in the editor. SQL keywords are automatically syntax-highlighted.
  3. Run — Click Run or press Ctrl+Enter to execute.
  4. View Results — Results appear in the table below the editor.
  5. Reset — Click Reset to restore the editor and results to their default state.

Good to Know

  • This playground uses the SQLite engine. Write queries in SQLite syntax.
  • INSERT, UPDATE, DELETE are supported, but refreshing the page restores the original data.
  • All processing happens in your browser. No data is sent to any server.

Data

This playground uses a compact version of the tutorial database (~200 rows per table). For the full dataset (750K rows), see Generate Data.
