$AGGMAP

The $AGGMAP property specifies the default AGGMAP type aggmap for a variable. When calculating the data in a variable, Oracle OLAP checks to see if the variable has an $AGGMAP property and, if it does, uses the aggmap object specified by that property as the default aggregation specification for a variable.

Tip:

You can also use a AGGMAP SET statement to specify the default aggregation specification for a variable or the $ALLOCMAP property to specify the default allocation specification for a variable.

See:

The PROPERTY command for general information on using properties in the OLAP DML.

Syntax

You add or delete an $AGGMAP property to the most recently defined or considered object (see DEFINE PROGRAM and CONSIDER) using a PROPERTY statement with the following syntax.

PROPERTY {addproperty | deleteproperty}

where

addproperty has the following syntax.

'$AGGMAP' agggmap-name
deleteproperty has the following syntax.

DELETE '$AGGMAP'

Arguments

aggmap-name: A TEXT expression that is the name of a previously defined aggmap object.
DELETE '$AGGMAP': Deletes the $AGGMAP property.

Examples

Example 6-1 Using the $AGGMAP Property

Example 6-2, "Using the $AGGREGATE_FROM Property" illustrates how the AGGREGATE command shown in Example 6-22, "Using a CACHE Statement in an Aggregation Specification" can be simplified to the following statement.

AGGREGATE sales_by_revenue USING revenue_aggmap

You can further simplify the AGGREGATE command if you place an $AGGMAP property on the sales_by_revenue variable. To define an $AGGMAP property on the sales_by_revenue variable, issue the following statements.

CONSIDER sales_by_revenue
PROPERTY ('$AGGMAP' 'revenue_aggmap')

Now you can aggregate the data by issuing the following AGGREGATE command that does not include a USING clause.

AGGREGATE sales_by_revenue
