You need to either (a) Drop and re-create the table rather than deleting rows - also *much* quicker, but you can't roll it back if you change your mind; (b) Configure more locks; (c) Delete the rows in smaller bunches and commit each bunch one at a time; but this could give you data integrity problems. akent@cix.compulink.co.uk (Andy Kent) -------------------------------------
