Oracle rollup operations-group by group, and calculate the total rollup for use with goup by, group by group, and calculate the total. Provides information aggregation (similar to "subtotal"). ROLLUP greatly facilitates rollup operations during data statistics and report generation-by group by rollup () the sum of grouping statistics means that if ROLLUP (A, B, C) is used, group by (A, B, C) is first performed, and then (A, B) perform group by, and then ()Group by, and then perform the group by
