Aggregate Functions in Oracle

Aggregate Functions
I will discuss five important aggregate functions: SUM, AVG, MAX, MIN, and COUNT. They are called
aggregate functions because they summarize the results of a query, rather than listing all of the rows.
SUM () gives the total of all the rows, satisfying any conditions, of the given column, where the given
column is numeric.
AVG () gives the average of the given column.
MAX () gives the largest figure in the given column.
MIN () gives the smallest figure in the given column.
COUNT(*) gives the number of rows satisfying the conditions.
