I have a "comment" field in a table that I want populated if another field has a certain value. Is it possible to set a check constraint for this?
Example: Let's say we have fields Purchase_type smallint check(purchase_type <4) comment varchar I need a check rule to something like (pseudo code) check (if purchase_type = 3 then NOT NULL comment) ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
