| Here's the if exists statement i wrote in a stored procedure, Is this efficient? Is there are a better way so there is not much of a delay? Any suggestions are appreciated.If Exists (select * from products where product_id = @id and prod_cd in (select prod_cd from prod where prod_type = 'toys' and prod_Active = 'Y')and prod_state = 'Y') update CUSTOMER set FLAG = 'Y',DATE = GETDATE() where product_id = @id and EMAIL_ADDRESS = @EMAIL else update CUSTOMER set FLAG = 'N',DATE = GETDATE() where product_id = @id and EMAIL_ADDRESS = @EMAIL |
