MySQL Reference Manual :: C.4.30 Changements de la version 3.23.31 (17 janvier 2001)

The test suite now tests all reachable BDB interface code. During testing we found and fixed many errors in the interface code.

Using HAVING on an empty table could produce one result row when it shouldn't.

Fixed the MySQL RPM so it no longer depends on Perl5.

Fixed some problems with HEAP tables on Windows.

SHOW TABLE STATUS didn't show correct average row length for tables larger than 4G.

CHECK TABLE ... EXTENDED didn't check row links for fixed size tables.

Added option MEDIUM to CHECK TABLE.

Fixed problem when using DECIMAL() keys on negative numbers.

HOUR() (and some other TIME functions) on a CHAR column always returned NULL.

Fixed security bug in something (please upgrade if you are using an earlier MySQL 3.23 version).

Fixed buffer overflow bug when writing a certain error message.

Added usage of setrlimit() on Linux to get -O --open-files-limit=# to work on Linux.

Added bdb_version variable to mysqld.

Fixed bug when using expression of type:

SELECT ... FROM t1 LEFT JOIN t2 ON (t1.a=t2.a) WHERE t1.a=t2.a

In this case the test in the WHERE clause was wrongly optimized away.

Fixed bug in MyISAM when deleting keys with possible NULL values, but the first key-column was not a prefix-compressed text column.

Fixed mysql.server to read the [mysql.server] option file group rather than the [mysql_server] group.

Fixed safe_mysqld and mysql.server to also read the server option section.

Added Threads_created status variable to mysqld.
