DIVIDEBYZERO

The DIVIDEBYZERO option controls the result of division by zero.

Data type

BOOLEAN

Syntax

DIVIDEBYZERO = YES|NO

Arguments

YES

Allows division by zero. A statement involving division by zero will execute without error; however, the result of the division by zero will be NA. When you are dividing by a dimensioned variable or expression, setting DIVIDEBYZERO to YES enables you to get results for most of the expression's values when a few calculations might involve dividing by zero.

NO

Disallows division by zero. A statement involving division by zero will stop executing and produce an error message. (Default)

Notes

Negative Powers of Zero

Raising zero to a negative power (for example, 0 ** -2) is division by zero.

Statements Affected by DIVIDEBYZERO

AGGREGATE command and AGGREGATE function

Examples

Example 11-13 The Effect of DIVIDEBYZERO

This example shows the effect of changing the value of the DIVIDEBYZERO option.

When you execute a SHOW command, such as the following, without changing the DIVIDEBYZERO option from its default value of NO, Oracle OLAP attempts to divide 100 by 0 and then produces an error message.

SHOW 100 / 0

When you change DIVIDEBYZERO to YES, the same statement executes without error and produces NA as the result of the division. The statements

DIVIDEBYZERO = YES
SHOW 100 / 0

produce the following result.

NA
