SQLite

3.7.0

Released on 22 Jul 2010
Project description.

SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. The code for SQLite is in the public domain and is thus free for use for any purpose, commercial or private. SQLite is the most widely deployed database in the world with more applications than we can count, including several high-profile projects.

SQLite is an embedded SQL database engine. Unlike most other SQL databases, SQLite does not have a separate server process. SQLite reads and writes directly to ordinary disk files. A complete SQL database with multiple tables, indices, triggers, and views, is contained in a single disk file. The database file format is cross-platform - you can freely copy a database between 32-bit and 64-bit systems or between big-endian and little-endian architectures. These features make SQLite a popular choice as an Application File Format.

SQLite 3.7.0 Changelog
  • Added support for write-ahead logging.
  • Query planner enhancement - automatic transient indices are created when doing so reduces the estimated query time.
  • Query planner enhancement - the ORDER BY becomes a no-op if the query also contains a GROUP BY clause that forces the correct output order.
  • Add the SQLITE_DBSTATUS_CACHE_USED verb for sqlite3_db_status().
  • The logical database size is now stored in the database header so that bytes can be appended to the end of the database file without corrupting it and so that SQLite will work correctly on systems that lack support for ftruncate().
