- People learning how SQL queries execute
- Worth noticing
- The lesson sequence follows FROM, JOIN, WHERE, GROUP BY, HAVING, SELECT, ORDER BY, and LIMIT.
Field notes
The interface combines a SQL editor with a clause-by-clause playback model, asking learners to predict intermediate results before advancing. Its documented sequence separates operations such as HAVING, SELECT, and ORDER BY rather than treating a query as a single opaque action. The current page shows a “SQLite engine not found” message and supplies setup instructions involving sql.js files, a local server, or Node’s built-in SQLite.
