$AGGREGATE_FROM

The $AGGREGATE_FROM property specifies the same behavior as that specified by a FROM clause in an AGGREGATE command or an AGGREGATE function. By adding an $AGGREGATE_FROM property to a variable you can ensure this behavior when the variable is aggregated — even when it is aggregated by an AGGREGATE statement does not include the FROM clause.

Both the $AGGREGATE_FROM property and the FROM clause specify an object from which Oracle OLAP obtains the detail data for the aggregation.

Syntax

You add or delete an $AGGREGATE_FROM property to the most recently defined or considered object (see DEFINE and CONSIDER commands) by issuing a PROPERTY statement:

Arguments

fromspec

An arbitrarily dimensioned variable, formula, or relation from which the detail data for the aggregation is obtained.

Examples

Example 5-3 Using the $AGGREGATE_FROM Property

Example 9-14, "Aggregating into a Different Variable" uses the following AGGREGATE command to populate the total_sales_exclud_north variable with aggregate values computed from the sales variable.

AGGREGATE total_sales_exclud_north USING agg_sales_exclud_north FROM sales

You can place a $AGGREGATE_FROM property on the total_sales_exclud_north variable by issuing the following statements.

CONSIDER total_sales_exclud_north
PROPERTY '$AGGREGATE_FROM' 'sales'

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

AGGREGATE total_sales_exclud_north USING agg_sales_exclud_north
