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"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.
AGGCOUNT(variable-name)
The name of the variable with which the Aggcount variable is associated.
Example 8-20 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 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 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.
REPORT sales PRODUCT: Radio -------------SALES-------------- --------------TIME-------------- GEOG 2004 2005 Average -------------- ---------- ---------- ---------- Maine 122.93 176.69 NA California 168.32 150.92 NA Quebec NA NA NA Ontario 187.46 164.46 NA USA NA NA NA Canada NA NA NA World NA NA NA PRODUCT: TV -------------SALES-------------- --------------TIME-------------- GEOG 2004 2005 Average -------------- ---------- ---------- ---------- Maine 184.75 135.40 NA California 139.89 145.71 NA Quebec NA NA NA Ontario 123.63 113.32 NA USA NA NA NA Canada NA NA NA World NA NA NA PRODUCT: AV -------------SALES-------------- --------------TIME-------------- GEOG 2004 2005 Average -------------- ---------- ---------- ---------- Maine NA NA NA California NA NA NA Quebec NA NA NA Ontario NA NA NA USA NA NA NA Canada NA NA NA World NA NA NA
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
Once aggregated a report of sales
shows the following values.
REPORT sales PRODUCT: Radio -------------SALES-------------- --------------TIME-------------- GEOG 2004 2005 Average -------------- ---------- ---------- ---------- Maine 122.93 176.69 149.81 California 168.32 150.92 159.62 Quebec NA NA NA Ontario 187.46 164.46 175.96 USA 291.24 327.61 309.42 Canada 187.46 164.46 175.96 World 478.70 492.07 485.38 PRODUCT: TV -------------SALES-------------- --------------TIME-------------- GEOG 2004 2005 Average -------------- ---------- ---------- ---------- Maine 184.75 135.40 160.07 California 139.89 145.71 142.80 Quebec NA NA NA Ontario 123.63 113.32 118.47 USA 324.64 281.11 302.87 Canada 123.63 113.32 118.47 World 448.27 394.42 421.35 PRODUCT: AV -------------SALES-------------- --------------TIME-------------- GEOG 2004 2005 Average -------------- ---------- ---------- ---------- Maine 307.67 312.08 309.88 California 308.21 296.63 302.42 Quebec NA NA NA Ontario 311.09 277.78 294.43 USA 615.88 608.71 612.30 Canada 311.09 277.78 294.43 World 926.97 886.49 906.73
A report of the Aggcount variable shows that it is populated with the INTEGER
values that are needed to aggregate the average sales.
