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 3.6.19 Changelog
  • Added support for foreign key constraints. Foreign key constraints are disabled by default. Use the foreign_keys pragma to turn them on.
  • Generalized the IS and IS NOT operators to take arbitrary expressions on their right-hand side.
  • The TCL Interface has been enhanced to use the Non-Recursive Engine (NRE) interface to the TCL interpreter when linked against TCL 8.6 or later.
  • Fix a bug introduced in 3.6.18 that can lead to a segfault when an attempt is made to write on a read-only database.
