AGGCOUNT

The AGGCOUNT function retrieves the values of the Aggcount variable associated with the specified variable. An Aggcount variable is an INTEGER variable that Oracle OLAP automatically creates when it creates a variable defined using a DEFINE VARIABLE statement that includes a USING AGGOUNT phrase.

See also:

"Aggcount Variables"

Return Value

INTEGER

The values of the Aggcount variable that are the non-NA counts of the number of leaf nodes that contribute to the calculation of aggregate values when RELATION (for aggregation) statements that have an AVERAGE, HAVERAGE, WAVERAGE, or HWAVERAGE execute.

Syntax

AGGCOUNT(variable-name)

Arguments

variable-name: The name of the variable with which the Aggcount variable is associated.

Examples

Example 7-3 Reporting on an Aggcount Variable

Assume that within your analytic workspace you have objects with the following definitions.

DEFINE geog DIMENSION TEXT
DEFINE time DIMENSION TEXT
DEFINE product DIMENSION TEXT
DEFINE cc_geog_product COMPOSITE <geog product> COMPRESSED
DEFINE sales VARIABLE DECIMAL <time cc_geog_product <geog product>> WITH AGGCOUNT
DEFINE geog_parentrel RELATION geog <geog>
DEFINE product_parentrel RELATION product <product>
DEFINE time_parentrel RELATION time <time>
DEFINE aggsales AGGMAP
   AGGMAP
   RELATION time_parentrel OPERATOR AVERAGE ARGS COUNT YES
   RELATION geog_parentrel
   RELATION product_parentrel
   END

Notice that the definition for the sales variable includes a request for an Aggcount variable and that, within the aggsales aggmap, the RELATION statement for the time_parentrel relation incudes an AVERAGE operator.

Assume also that when only the base values of the sales variable are populated, sales has the following values for Radios and TVs.

Since no aggregation has occurred, for AV, Oracle OLAP has not yet populated the Aggcount variable and the Aggcount variable for sales contains only NA values.

Now assume that you aggregate the sales variable by issuing the following statement.

AGGREGATE sales USING aggsales

A report of sales shows the following values.
