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 2.8.1 Changelog
  • Reactivated the VACUUM command that reclaims unused disk space in a database file.
  • Added the ATTACH and DETACH commands to allow interacting with multiple database files at the same time.
  • Added support for TEMP triggers and indices.
  • Added support for in-memory databases.
  • Removed the experimental sqlite_open_aux_file(). Its function is subsumed in the new ATTACH command.
  • The precedence order for ON CONFLICT clauses was changed so that ON CONFLICT clauses on BEGIN statements have a higher precedence than ON CONFLICT clauses on constraints.
  • Many, many bug fixes and compatibility enhancements.
