Hi! I'm experiencing a very slow deletion of records. Which I thin is not right. I have a Dual Xeon Server with 6gig Memory. I am only deleting about 22,000 records but it took me more than 1 hour to finish this. What could possibly I do so that I can make this fast? Here is the code inside my function: FOR temp_rec IN SELECT * FROM item_qc_doer LOOP DELETE FROM qc_session WHERE item_id = temp_rec.item_id; DELETE FROM item_qc_doer WHERE item_id = temp_rec.item_id; END LOOP; Item_qc_oder table contains 22,000 records. I choose Polesoft Lockspam to fight spam, and you? http://www.polesoft.com/refer.html
