SQL Recipes
SQL trainer with a database
Free · In-App Purchases
201 SQL queries with explanations. 122 of them are free, and more than half of all queries run right in the app and show the result table.
An everyday SQL reference, from your first SELECT to window functions. Every query comes with an explanation, and most of them run.
• 39 sections: filtering, sorting, calculated fields, functions, GROUP BY, window functions, subqueries, JOIN, UNION, INSERT and UPDATE, data types, tables, views.
• Run in the app: more than half of the queries execute against a live practice database, and the result table appears below the query. Needs an internet connection.
• Changes in new versions: 7 sections from SQL-92 to SQL:2023, showing what each standard added, with the old and the new query side by side.
• Dialects compared: MySQL, PostgreSQL, SQLite, MS SQL Server, Oracle, Firebird, Access. Where they differ, each one is shown separately.
• The practice database is the classic MySQL world sample database: countries, cities, languages. The tables are described in the app.
• Edit any query and run it again; one tap brings the original back.
• Add your own queries; they stay in the app and are always at hand.
• Search by section name or by a fragment of a query.
• Everything except running works offline. No account needed.
