Those unix_time values don't seem to correspond to the dates you have. select NOW(), UNIX_TIMESTAMP(NOW()); +---------------------+-----------------------+ | NOW() | UNIX_TIMESTAMP(NOW()) | +---------------------+-----------------------+ | 2010-10-04 13:18:08 | 1286223488 | +---------------------+-----------------------+
1286223428 vs 12862162510269684 Your value has far too many digits. That's also beyond the range of a 32 bit int. Are you using BIGINT, or VARCHAR? I suspect the issues is due because of something different about the values you have in your table. Try posting the SHOW CREATE TABLE table \G output, and a sample INSERT statement to populate the table. That way someone can try to reproduce the behavior you're seeing. -----Original Message----- From: kalin m [mailto:ka...@el.net] Sent: Monday, October 04, 2010 1:11 PM To: [MySQL] Subject: update and times hi all... i'm doing tests with a table that gets updated based on random unix times it contains. there is a column that has a bunch or random times that look like: +---------------------+-------------------+ | date_time | unix_time | +---------------------+-------------------+ | 2010-10-01 10:24:52 | 12859430921341418 | | 2010-10-01 21:18:13 | 12859822937839442 | | 2010-10-01 16:08:00 | 12859636809115039 | | 2010-10-01 19:47:43 | 12859768633824661 | | 2010-10-01 16:48:30 | 12859661104829142 | | 2010-10-01 15:25:37 | 12859611374324533 | | 2010-10-01 12:27:28 | 12859504483288358 | +---------------------+-------------------+ what i'm trying to do is update the column only of one of those times isn't yet passed. and it works. except sometimes... like these 2 unix times: this was in the table under unix time: 12862162385941345... this 12862162510269684 got passed in the update command as in: update the_table set updated = 1 where unix_time < 12862162510269684 limit 1; executing this query didn't update the record. why? thanks... -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql?unsub=gto...@ffn.com This message contains confidential information and is intended only for the individual named.
