SQLite

2.3.0

Released on 30 Jan 2002
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 2.3.0 Changelog
  • Fix a serious bug in the INSERT command which was causing data to go into the wrong columns if the data source was a SELECT and the INSERT clauses specified its columns in some order other than the default.
  • Added the ability to resolve constraint conflicts is ways other than an abort and rollback. See the documentation on the "ON CONFLICT" clause for details.
  • Temporary files are now automatically deleted by the operating system when closed. There are no more dangling temporary files on a program crash. (If the OS crashes, fsck will delete the file after reboot under Unix. I do not know what happens under Windows.)
  • NOT NULL constraints are honored.
  • The COPY command puts NULLs in columns whose data is '\N'.
  • In the COPY command, backslash can now be used to escape a newline.
  • Added the SANITY_CHECK pragma.
