Hi I am INNODB tables only. (I have only one big table) Autocommit I have already disabled. And it doesn't have any foreign keys in it. Do I still need to set the FOREIGN_KEY_CHECKS to '0'??

If it is, and it is a clean import, then disable the FOREIGN_KEY_CHECKS. SET AUTOCOMMIT = 0; SET FOREIGN_KEY_CHECKS=0; This is a small tip i picked up on the MySQL documentation that someone had left in the comments and has been to date one of those tips that has literally saved DAYS of my life. a ps Remember to put them back on again after you finish the import SET AUTOCOMMIT = 1; SET FOREIGN_KEY_CHECKS=1; -- Alan Williamson, Technology Evangelist SpikeSource Inc.
