I wouuld like to have the update happen in steps with loop to avoid getting the entire table locked. Also, I do fine the query takes around 10.88 secs to update to complete. this is one reason i prefer to have update happen in steps so that entire table locking do not happen. its innodb table. Regards Harish Hi,
