UPDATE table1 SET price = (SELECT price FROM table2 WHERE table1.product = table2.product); -- Oliver Elphick [EMAIL PROTECTED] Isle of Wight, UK http://www.lfix.co.uk/oliver GPG: 1024D/3E1D0C1C: CA12 09E0 E8D5 8870 5839 932A 614D 4C34 3E1D 0C1C ======================================== "And he said unto his disciples, Therefore I say unto you, Take no thought for your life, what ye shall eat; neither for the body, what ye shall put on. For life is more than meat, and the body is more than clothing. Consider the ravens, for they neither sow nor reap; they have neither storehouse nor barn; and yet God feeds them; how much better you are than the birds! Consider the lilies, how they grow; they toil not, they spin not; and yet I say unto you, that Solomon in all his glory was not arrayed like one of these. If then God so clothe the grass, which is to day in the field, and tomorrow is cast into the oven; how much more will he clothe you, O ye of little faith? And seek not what ye shall eat, or what ye shall drink, neither be ye of doubtful mind. But rather seek ye the kingdom of God; and all these things shall be added unto you."
