The term for that sort of query is a catch-all query. There are several ways to write them. Here is one:select * from Customerwhere (CustmerNumber=@CustomerNumber or @CustomerNumber IS NULL) and (Date_Customer=@date_Customer or @date_Customer IS NULL) Here is a link that gives more detail on these types of queries:http://sqlinthewild.co.za/index.php/2009/03/19/catch-all-queries/ |
