If I remember correctly, in SQL Server, it is not recommended to use "ORDER BY" when there's already a GROUP BY GROUPING SETS.I have two columns: [UPC#] & [Description] both are varchar.My grouping sets is like this:GROUP BY GROUPING SETS ( ([UPC],[Description]) ,() ) I don't have 'ORDER BY' but it's automatically sorting the Description column.If I added a 3rd column, sum(Qty), then it doesn't sort by Description anymore. But if I addedORDER BY [Description] then the grand total of sum(Qty) will be at the first row instead of the last.Is there a way to sort the Description column and still let the grand total of sum(Qty) be at the last row instead?Thanks. |

GROUP BY does not sort data. Sets have no order.Your data will be outputed in the order the CPU processes the groups, which can be different between executions.Most common when statistics change.Use ORDER BY GROUPING(...) Microsoft SQL Server MVP, MCT, MCSE, MCSA, MCP, MCITP, MCTS, MCDBA |
