Averages in OBIEE


Averages in OBIEE


AVG


This function calculates the average (mean) value of an expression in a result set. It must take a numeric expression as its argument.

Note that the denominator of AVG is the number of rows aggregated. For this reason, it is usually a mistake to use AVG(x) in a calculation in Oracle Business Intelligence. Instead, write the expression manually so that you can control both the numerator and denominator (x/y).

Syntax

AVG(numExpr)

Where:

numExpr is any expression that evaluates to a numeric value.

AVGDISTINCT


This function calculates the average (mean) of all distinct values of an expression. It must take a numeric expression as its argument.

Syntax

AVG(DISTINCT numExpr)

Where:

numExpr is any expression that evaluates to a numeric value.
