GNU Info (mysql.info)News-3.22.2Changes in release 3.22.2 ------------------------- * Searching on multiple constant keys that matched more than 30% of the rows didn't always use the best possible key. * New functions `<<', `>>', `RPAD()' and `LPAD()'. * You can now save default options (like passwords) in a configuration file (`my.cnf'). * Lots of small changes to get `ORDER BY' to work when no records are found when using fields that are not in `GROUP BY' (MySQL extension). * Added `--chroot' option to `mysqld', to start `mysqld' in a chroot environment (by Nikki Chumakov <nikkic@cityline.ru>). * Trailing spaces are now ignored when comparing case-sensitive strings; this should fix some problems with ODBC and flag 512! * Fixed a core-dump bug in the range optimizer. * Added `--one-thread' option to `mysqld', for debugging with LinuxThreads (or `glibc'). (This replaces the `-T32' flag) * Added `DROP TABLE IF EXISTS' to prevent an error from occurring if the table doesn't exist. * `IF' and `EXISTS' are now reserved words (they would have to be sooner or later). * Added lots of new options to `mysqldump'. * Server error messages are now in `mysqld_error.h'. * The server/client protocol now supports compression. * All bug fixes from MySQL Version 3.21.32. automatically generated by info2www version 1.2.2.9 |
