AggregateFunction (Measure Interface)
[!NOTA]
Esta característica se quitará en la versión siguiente de Microsoft SQL Server. No utilice esta característica en nuevos trabajos de desarrollo y modifique lo antes posible las aplicaciones que actualmente la utilizan.
The AggregateFunction property of the Measure interface contains an enumeration constant that corresponds to the type of aggregate function used to generate the precalculated value of the measure.
Applies To:clsAggregationMeasure, clsCubeMeasure, clsPartitionMeasure
Access
Access depends on the value of the ClassType property of the object.
Class type |
Access |
|---|---|
clsAggregationMeasure |
R |
clsCubeMeasure |
R/W* |
clsPartitionMeasure |
R |
* Read-only for virtual cube measures and measures in fully-created linked cubes.
Notas
To create more sophisticated measures (for example, ratios or statistical functions), use the command object to create a calculated member. For more information, see clsCubeCommand and clsDatabaseCommand.
[!NOTA]
Because the DISTINCT COUNT aggregation function does not support custom aggregations, the use of this aggregation function in combination with the CustomRollupExression and CustomRollupColumn properties is not supported. If a cube uses the DISTINCT COUNT aggregation function and any of the dimensions in that cube use either the CustomRollupExpression property or the CustomRollupColumn property, including data mining dimensions, the cube is invalid. Processing such a cube raises a validation error.
Examples
Reading the AggregateFunction Property of a Measure Object
Use the following code to read the value of the AggregateFunction property of a measure object:
'Assume an object (dsoAggMea) of ClassType clsAggregationMeasure exists
Dim AggType As DSO.AggregatesTypes
AggType = dsoAggMea.AggregateFunction
Select Case AggType
Case aggSum
' Insert code for aggregation summation.
Case aggCount
' Insert code for aggregation counts.
Case aggMin
' Insert code for aggregation min.
Case aggMax
' Insert code for aggregation max.
Case aggDistinctCount
' Insert for aggregation distinct counts.
End Select
