In the preceding topic we saw how the GROUPING function could be used to identify null values representing the set of all values produced by a GROUPING SETS, ROLLUP, or CUBE operation. The WITH ROLLUP modifer adds extra rows to the resultset that represent super-aggregate summaries. This particular article focuses on ROLLUP, which is pretty similar to CUBE except you would use it when there is a natural hierarchy formed by the elements of the GROUPING SETS. These operators perform multi level aggregations at each column specified in the GROUP BY Clause. Many of us probably give up early and calculate stuff in Java / [or your language]. These operators are used with the GROUP BY clause and allow you to create subtotals, grand totals and superset of subtotals. The ROLLUP, CUBE, and GROUPING SETS operators are extensions of the GROUP BY clause. HOW TO USE ROLLUP: The ROLLUP operator is useful in generating reports that contain subtotals and totals.
