D.4.49. Alterações na distribuição 3.23.12 (07 Mar 2000)

  • Fixed bug in MyISAM involving REPLACE ... SELECT ... which could give a corrupted table.

  • Fixed bug in myisamchk where it incorrectly reset the AUTO_INCREMENT value.

  • LOTS of patches for Linux Alpha. MySQL now appears to be relatively stable on Alpha.

  • Changed DISTINCT on HEAP temporary tables to use hashed keys to quickly find duplicated rows. This mostly concerns queries of type SELECT DISTINCT ... GROUP BY .... This fixes a problem where not all duplicates were removed in queries of the above type. In addition, the new code is MUCH faster.

  • Added patches to make MySQL compile on Mac OS X.

  • Added IF NOT EXISTS clause to CREATE DATABASE.

  • Added --all-databases and --databases options to mysqldump to allow dumping of many databases at the same time.

  • Fixed bug in compressed DECIMAL() index in MyISAM tables.

  • Fixed bug when storing 0 into a timestamp.

  • When doing mysqladmin shutdown on a local connection, mysqladmin now waits until the PID file is gone before terminating.

  • Fixed core dump with some COUNT(DISTINCT ...) queries.

  • Fixed that myisamchk works properly with RAID tables.

  • Fixed problem with LEFT JOIN and key_field IS NULL.

  • Fixed bug in net_clear() which could give the error Aborted connection in the MySQL clients.

  • Added options USE INDEX (key_list) and IGNORE INDEX (key_list) as parameters in SELECT.

  • DELETE and RENAME should now work on RAID tables.
