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 3.7.1 Changelog
  • Added new commands SQLITE_DBSTATUS_SCHEMA_USED and SQLITE_DBSTATUS_STMT_USED to the sqlite3_db_status() interface, in order to report out the amount of memory used to hold the schema and prepared statements of a connection.
  • Increase the maximum size of a database pages from 32KiB to 64KiB.
  • Use the LIKE optimization even if the right-hand side string contains no wildcards.
  • Added the SQLITE_FCNTL_CHUNK_SIZE verb to the sqlite3_file_control() interface for both unix and windows, to cause database files to grow in large chunks in order to reduce disk fragmentation.
  • Fixed a bug in the query planner that caused performance regressions relative to on some complex joins.
  • Fixed a typo in the OS/2 backend.
  • Refactored the pager module.
  • The SQLITE_MAX_PAGE_SIZE compile-time option is now silently ignored. The maximum page size is hard-coded at 65536 bytes.
