You are quite right, rules basically act like macros with all the limitations they have. What is actually happening behind the scenes is that the query is being rewritten to alter the query-plan tree. You should be able to get your rule to work by referring to currval() rather than NEW.custid. However, in this particular case I think you want an after insert trigger on customer rather than a rule. -- Richard Huxton Archonet Ltd
