Hey all - I have a table with 12,000,000 records spread over about 6 years. I'm trying to delete all but the last 2 years, but no matter how small of a group I try to delete at a time, it keeps hanging up the server and I eventually have to restart MySQL. The table looks like this:
`creation` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP, `lat` double NOT NULL default '0', `lon` double NOT NULL default '0', `referer` int(12) NOT NULL default '0', PRIMARY KEY (`referer`,`lat`,`lon`), KEY `creation` (`creation`,`referer`) And the query I've been trying looks like this: delete from tablename where `creation` < '2006-04-01 00:00:00' ...trying to do the oldest 1 month of records at a time. So am I just trying a really inefficient query? Is there a better way to do this? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql?unsub=arch...@jab.org
