| >>( I tried to put my scenario in a generic way.)Then here's a generic answer:You need a table of all your groupings (product,year). say ProdYear_tblThen LEFT OUTER JOIN to your data table correlating on the grouping columns. SELECT the grouping values from the PRodYear table and sum the amount from your data table. That way you have a row for all possibilities even if the amount is null.Be One with the OptimizerTG |
