Hi... I have problem with update query. Select query with the same "where" is OK.
mysql> select AcctStartTime,AcctSessionTime from radacct where AcctStopTime is null; +---------------------+-----------------+ | AcctStartTime | AcctSessionTime | +---------------------+-----------------+ | 2005-04-11 12:16:19 | 191154 | | 2005-04-13 06:51:59 | 37984 | | 2005-04-13 16:28:51 | 3617 | | 2005-04-13 17:36:57 | 16279 | | 2005-04-13 17:37:01 | 16280 | | 2005-04-13 17:37:03 | 16279 | | 2005-04-13 22:15:41 | 0 | | 2005-04-13 22:15:56 | 0 | | 2005-04-13 22:23:55 | 44018 | | 2005-04-14 10:34:14 | 0 | +---------------------+-----------------+ 10 rows in set (0.00 sec) but update: mysql> update radacct set AcctStopTime=null where AcctStopTime is null; Query OK, 0 rows affected (0.00 sec) I know that this update query is stupid byt it is only to show problem. this is more/less my table: mysql> desc radacct; +--------------------+-------------+------+-----+---------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------------------+-------------+------+-----+---------------------+----------------+ | RadAcctId | bigint(21) | | PRI | NULL | auto_increment | | AcctStartTime | datetime | | MUL | 0000-00-00 00:00:00 | | | AcctStopTime | datetime | | MUL | 0000-00-00 00:00:00 | | | AcctSessionTime | int(12) | YES | | NULL | | my sql system/version: debian/mysql 4.1.11 -- Emil Wilmanski <[EMAIL PROTECTED]> Galeria-M -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
