The $AGGREGATE_FROMVAR property specifies the same behavior as that specified by a FROMVAR clause in an AGGREGATE command or an AGGREGATE function. By adding an $AGGREGATE_FROMVAR 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 FROMVAR clause.

Both the $AGGREGATE_FROMVAR property and the FROMVAR clause specify two or more objects from which Oracle OLAP obtains the detail data for the aggregation.


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



A TEXT expression that specifies an arbitrarily dimensioned variable or formula that specifies the names of the objects from which to obtain detail data when performing a capstone aggregation. Specify NA to indicate that a node does not need detail data to calculate the value.

ACROSS dimname

Specifies the dimension or a named composite that the aggregation loops over to discover the cells in the objects specified by textvar. Because the objects specified by textvar can be formulas, you can realize a significant performance advantage by supplying a looping dimension that eliminates the sparsity.


Example 4-4 Capstone Aggregation Using the $AGGREGATE_FROMVAR Property

Example 9-32, "Capstone Aggregation" uses the following AGGREGATE command to perform the final capstone aggregation.

AGGREGATE sales_capstone76 USING capstone_aggmap FROMVAR capstone_source

As the following statements illustrate, you can omit the FROMVAR clause if you create the appropriate FROMVAR property on sales-capstone76.

CONSIDER sales_capstone76
PROPERTY '$AGGREGATE_FROMVAR'  'capstone_source'
AGGREGATE sales_capstone76 USING capstone_aggmap
