Released on 18 Oct 2000
MySQL 3.23.26 Changelog

End of Product Lifecycle. Active development and support for MySQL Database Server versions 3.23, 4.0, and 4.1 has ended. For details, see http://www.mysql.com/about/legal/lifecycle/#calendar. Please consider upgrading to a recent version. Further updates to the content of this manual will be minimal. All formats of this manual will continue to be available until 31 Dec 2010.

  • Renamed FLUSH MASTER and FLUSH SLAVE to RESET MASTER and RESET SLAVE.

  • Fixed <> to work properly with NULL.

  • Fixed a problem with SUBSTRING_INDEX() and REPLACE(). (Patch by Alexander Igonitchev)

  • Fix CREATE TEMPORARY TABLE IF NOT EXISTS not to produce an error if the table exists.

  • If you don't create a PRIMARY KEY in a BDB table, a hidden PRIMARY KEY is created.

  • Added read-only-key optimization to BDB tables.

  • LEFT JOIN in some cases preferred a full table scan when there was no WHERE clause.

  • When using --log-slow-queries, don't count the time waiting for a lock.

  • Fixed bug in lock code on Windows which could cause the key cache to report that the key file was crashed even if it was okay.

  • Automatic repair of MyISAM tables if you start mysqld with --myisam-recover.

  • Removed the TYPE= keyword from CHECK TABLE and REPAIR TABLE. Permit CHECK TABLE options to be combined. (You can still use TYPE=, but this usage is deprecated.)

  • Fixed mutex bug in the binary replication log --- long update queries could be read only in part by the slave if it did it at the wrong time, which was not fatal, but resulted in a performance-degrading reconnect and a scary message in the error log.

  • Changed the format of the binary log --- added magic number, server version, binary log version. Added the server ID and query error code for each query event.

  • Replication thread from the slave now kills all the stale threads from the same server.

  • Long replication user names were not being handled properly.

  • Added --replicate-rewrite-db option to mysqld.

  • Added --skip-slave-start option to mysqld.

  • Updates that generated an error code (such as INSERT INTO foo(some_key) values (1),(1)) erroneously terminated the slave thread.

  • Added optimization of queries where DISTINCT is used only on columns from some of the tables.

  • Permit floating-point numbers where there is no sign after the exponent (like 1e1).

  • SHOW GRANTS didn't always show all column grants.

  • Added --defaults-extra-file=file_name option to all MySQL clients.

  • Columns referenced in INSERT statements now are initialized properly.

  • UPDATE didn't always work when used with a range on a timestamp that was part of the key that was used to find rows.

  • Fixed a bug in FULLTEXT index when inserting a NULL column.

  • Changed to use mkstemp() instead of tempnam(). Based on a patch from John Jones.
