SQLite

3.8.2

Released on 6 Dec 2013
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 3.8.2 Changelog
  • Changed the defined behavior for the CAST expression when floating point values greater than +9223372036854775807 are cast into into integers so that the result is the largest possible integer, +9223372036854775807, instead of the smallest possible integer, -9223372036854775808. After this change, CAST(9223372036854775809.0 as INT) yields +9223372036854775807 instead of -9223372036854775808.  Potentially Incompatible Change!
  • Added support for WITHOUT ROWID tables.
  • Added the skip-scan optimization to the query planner.
  • Extended the virtual table interface, and in particular the sqlite3_index_info object to allow a virtual table to report its estimate on the number of rows that will be returned by a query.
  • Update the R-Tree extension to make use of the enhanced virtual table interface.
  • Add the SQLITE_ENABLE_EXPLAIN_COMMENTS compile-time option.
  • Enhanced the comments that are inserted into EXPLAIN output when the SQLITE_ENABLE_EXPLAIN_COMMENTS compile-time option is enabled.
  • Performance enhancements in the VDBE, especially to the OP_Column opcode.
  • Factor constant subexpressions in inner loops out to the initialization code in prepared statements.
  • Enhanced the ".explain" output formatting of the command-line shell so that loops are indented to better show the structure of the program.
  • Enhanced the ".timer" feature of the command-line shell so that it shows wall-clock time in addition to system and user times.
  • SQLITE_SOURCE_ID: "2013-12-06 14:53:30 27392118af4c38c5203a04b8013e1afdb1cebd0d"
