In an effort to speed up large batch deletes i devised this script. LOCK TABLES t1 WRITE; SELECT * INTO OUTFILE '/data/dump/t1' FROM t1 where date>="2003-06-09"; TRUNCATE TABLE t1; LOAD DATA INFILE '/data/dump/t1' INTO TABLE t1; UNLOCK TABLES;
this script would work great without the LOCK TABLES clause. I receive an error saying there active locked tables. This is a heap table and I am running mysql 4.0.12 Any ideas? i need the lock tables because there are some updates that will be happening to the current data, i just need to remove the old expired data. This takes about 30secs and my delete scripts takes about 4 hours. It is deleting about 500,000 rows out of a 4 million row table with several indexes. -Todd -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
