Even with multiple grouping columns, older SQL versions provide only a single level of grouping. The query produces a separate summary row for each salesperson/customer pair. To produce more than one level of subtotals in more modern SQL, you can use the WITH ROLLUP and WITH CUBE operators in combination with the GROUP BY operator. WITH ROLLUP causes the GROUP BY operation to display a subtotal for each level of grouping working left to right across the list of grouping columns. WITH CUBE goes further by showing subtotals for every possible combination of grouping columns. WITH CUBE and WITH ROLLUP also provide a grand total in the result set, but the grand total might not always appear at the end of the result set. Oracle s CUBE option, for example, displays the grand total first. You can spot the subtotal rows because grouping columns that don t apply are NULL. Similarly, the grand total line will have NULL values in all of the grouping columns. Calculate the total orders for each customer of each salesperson with subtotals for each salesperson.

Summary Queries
The syntax for WITH ROLLUP and WITH CUBE varies somewhat from one SQL product to another, so check your vendor s documentation. The SQL standard syntax, which is supported by SQL Server, DB2 Universal Database (UDB), and MySQL, is shown in the preceding examples. (However, as of version 5.1, MySQL does not yet support WITH CUBE.) Oracle requires the keywords GROUP BY ROLLUP or GROUP BY CUBE followed by the grouping column list, which must be enclosed in parentheses, such as: GROUP BY CUBE (REP, CUST). DB2 UDB supports both the standard syntax and the variation required by Oracle. If your SQL implementation does not support ROLLUP or CUBE, the best you can do is sort the data so that the rows of query results appear in the appropriate order. In many SQL implementations, the GROUP BY clause will automatically have the side-effect of sorting the data, but you can override this sort with an ORDER BY clause, as shown next: Calculate the total orders for each customer of each salesperson, sorted by customer, and within each customer by salesperson.
