AGGREGATE FUNCTIONS

• Set functions apply to sets of rows in a table rather than to a single row. These functions summarize some characteristic of the current set of rows. The set may include all the rows in the table or a subset of rows that are specified by a WHERE clause. • Programmers sometimes call set functions aggregate functions because these functions take information from multiple rows, process that information in some way, and deliver a single-row answer.
