Browse, search, or tap a word in a query to open its article. • Dialects compared: MySQL, PostgreSQL, SQLite, SQL Server, Oracle, Firebird, Access. Where they differ, the dialect-specific variants are shown. • Practice database: the classic MySQL “world” sample (countries, cities, spoken languages); its tables are described in the app. • Run in the app: more than half of the queries execute against the practice database, and the result table appears directly below the query. Requires an internet connection. • Search covers the queries themselves, not just titles: type a fragment you remember and find the query. • Edit queries and rerun the runnable ones; one tap brings the original back. • Add your own queries; they are saved in the app. • Everything except running queries works offline. No account needed. Queries are curated from professional sources and checked before release: the code works and is easy to follow. FREE VERSION • 12 runs and 12 edits a day • Full keyword and function reference; tap a word in a query for up to 12 articles a day • Up to 5 queries of your own The full version unlocks every query, removes the limits on edits and on your own queries, and raises the daily run limit to 80.
