Try the ROLLUP analytical function. ROLLUP enables an SQL statement to calculate multiple levels of subtotals across a specified group of dimensions. It also calculates a grand total. ROLLUP is a simple extension to the GROUP BY clause, so its syntax is extremely easy to use. It also only does one-pass through the table, so it's efficient too!
SELECT deptno, job, count(*), sum(sal) FROM emp GROUP BY ROLLUP(deptno,job); DEPTNO JOB COUNT(*) SUM(SAL) --------- --------- --------- --------- 10 CLERK 1 1300 10 MANAGER 1 2450 10 PRESIDENT 1 5000 10 3 8750 20 ANALYST 2 6000 20 CLERK 2 1900 20 MANAGER 1 2975 20 5 10875
