Download SQLite 3.39.0

SQLite is a database system developed in C that can be used for websites and embedded applications, among other things. According to the developers, SQLite requires no installation and administration, supports databases up to two terabytes in size and stores an entire database in one file. Furthermore, it supports almost the full SQL92 specification and it is easy via, among others Tcl/Tk to guide. Version 3.39.0 has been released with the following changes:

Version 3.39.0

• Add (long overdue) support for RIGHT and FULL OUTER JOIN.
• Add new binary comparison operators IS NOT DISTINCT FROM and IS DISTINCT FROM that are equivalent to IS and IS NOT, respectively, for compatibility with PostgreSQL and SQL standards.
• Add a new return code (value “3”) from the sqlite3_vtab_distinct() interface that indicates a query that has both DISTINCT and ORDER BY clauses.
• Added the sqlite3_db_name() interface.
• The unix os interface resolves all symbolic links in database filenames to create a canonical name for the database before the file is opened.
• Defer materializing views until the materialization is actually needed, thus avoiding unnecessary work if the materialization turns out to never be used.
• The HAVING clause of a SELECT statement is now allowed on any aggregate query, even queries that do not have a GROUP BY clause.
• Many microoptimizations collectively reduce CPU cycles by about 2.3%.
