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 3.6.18 Changelog
  • Versioning of the SQLite source code has transitioned from CVS to Fossil.
  • Query planner enhancements.
  • The SQLITE_ENABLE_STAT2 compile-time option causes the ANALYZE command to collect a small histogram of each index, to help SQLite better select among competing range query indices.
  • Recursive triggers can be enabled using the PRAGMA recursive_triggers statement.
  • Delete triggers fire when rows are removed due to a REPLACE conflict resolution. This feature is only enabled when recursive triggers are enabled.
  • Added the SQLITE_OPEN_SHAREDCACHE and SQLITE_OPEN_PRIVATECACHE flags for sqlite3_open_v2() used to override the global shared cache mode settings for individual database connections.
  • Added improved version identification features: C-Preprocessor macro SQLITE_SOURCE_ID, C/C++ interface sqlite3_sourceid(), and SQL function sqlite_source_id().
  • Obscure bug fix on triggers([efc02f9779]).
