Subject: Batch Deletes...
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
