Introduction to Oracle aggregate functions. Oracle aggregate functions calculate on a group of rows and return a single value for each group. We commonly use the aggregate functions together with the GROUP BY clause. The GROUP BY clause divides the rows into groups and an aggregate function calculates and returns a single result for each group.
