NONE

The NONE function returns YES when none of the values of a Boolean expression are TRUE. It returns NO when any value of the expression is TRUE.

Return Value

BOOLEAN or NA if all the values of the expression are NA

Syntax

NONE(boolean-expression [dimension...])

Arguments

boolean-expression

The Boolean expression to be evaluated.

dimension

The name of a dimension of the result; or, the name of a relation between one of the dimensions of boolean-expression and another dimension that you want as a dimension of the result.

By default, NONE returns a single YES or NO value. When you indicate one or more dimensions for the result, NONE tests for TRUE values along the dimensions that are specified and returns an array of values. Each dimension must be either a dimension of boolean-expression or related to one of its dimensions.

Tip:

When you specify a dimension that is not an actual dimension of boolean-expression, but, instead, is dimension that is related to a dimension of boolean-expression and when there is more than one relation between the two dimensions, Oracle OLAP uses the default relation between the dimensions to perform the calculation. (See the RELATION command for more information on default relations.) When you do not want Oracle OLAP to use this default relation, specify the related dimension by specifying the name of a specify relation.

Notes

The Effect of NASKIP on NONE

NONE is affected by the NASKIP option. When NASKIP is set to YES (the default), and all of the values in the expression are NA NONE returns NA; if even one value is not NA, NONE ignores all of the NA values in the expression. When NASKIP is set to NO, NONE returns NA when any value of the expression is NA.

Examples

Example 20-28 Testing for No True Values by District

Suppose you want to find out which districts had no months in which sales fell below $50,000. Use the NONE function to determine whether the Boolean expression (SALES LT 50000) is TRUE for no months. To have the results dimensioned by district, specify district as the second argument to NONE.

LIMIT product TO 'Sportswear'
REPORT NONE(sales LT 50000, district)

The preceding statements produce the following output.

NONE(SALES
               LT 50000,
DISTRICT       DISTRICT)
-------------- ----------
Boston                 NO
Atlanta               YES
Chicago               YES
Dallas                YES
Denver                YES
Seattle                NO

Example 20-29 Testing for No True Values by Region

You might also want to find out which regions had no months in which no districts had sportswear sales of less than $50,000. Since the region dimension is related to the district dimension, you can specify region instead of district as a dimension for the results of ANY.

REPORT NONE(sales LT 50000, region)

The preceding statement produces the following output.

NONE(SALES
               LT 50000,
REGION          REGION)
-------------- ----------
East                   NO
Central               YES
West                   NO
