Stephan Oudmaijer meldt ons dat er een nieuwe MySQL ter download wordt aangeboden. De changelog is dit keer niet zo enorm groot en staat daarom hieronder:
[break] MySQL 3.23.47-Max heeft een aantal belangrijke bugfixes voor gebruikers van InnoDB tables. ORDER BY en DISTINCT queries op grote tabellen hebben in deze versie een betere performance. Zie voor info de InnoDB changelog en InnoDB bugfix pagina: [/break] MySQL/InnoDB-3.23.47
- InnoDB now supports NULL in keys.
- Fixed shutdown problem on HPUX. (Introduced in 3.23.46)
- Added 'DO expression' command.
- Fixed core-dump bug in replication when using SELECT RELEASE_LOCK();
- Added new statement DO expression,[expression].
- Added slave-skip-errors option
- Added statistics variables for all MySQL commands. (SHOW STATUS is now much longer).
- Fixed default values for InnoDB tables.
- Fixed that GROUP BY expr DESC works.
- Fixed bug when using t1 LEFT JOIN t2 ON t2.key=constant.
- mysql_config now also work with binary (relocated) distributions.
- InnoDB allows now several similar key values in a UNIQUE secondary index if those values contain SQL NULLs. Thus the convention is now the same as in MyISAM tables.
- InnoDB gives a better row count estimate for a table which contains BLOBs.
- In a FOREIGN KEY constraint InnoDB is now case-insensitive to column names, and in Windows also to table names.
- InnoDB allows a FOREIGN KEY column of CHAR type to refer to a column of VARCHAR type, and vice versa. MySQL silently changes the type of some columns between CHAR and VARCHAR, and these silent changes do not hinder FOREIGN KEY declaration any more.
- Recovery has been made more resilient to corruption of log files.
- Unnecessary statistics calculation has been removed from queries which generate a temporary table. Some ORDER BY and DISTINCT queries will now run much faster.
- MySQL now knows that the table scan of an InnoDB table is done through the primary key. This will save a sort in some ORDER BY queries.
- The maximum key length of InnoDB tables is again restricted to 500 bytes. The MySQL interpreter is not able to handle longer keys.
