CustomRollupColumn (Level Interface)

注意：
下一版本的 Microsoft SQL Server 将删除该功能。请不要在新的开发工作中使用该功能，并尽快修改当前还在使用该功能的应用程序。

The CustomRollupColumn property of the Level interface contains the name of the column that stores member-specific rollup instructions.

Applies To:clsAggregationLevel, clsCubeLevel, clsDatabaseLevel, clsPartitionLevel

Data Type

String

Access

Access depends on the value of the ClassType property of the object.

备注

The string values in this column should contain valid Multidimensional Expressions (MDX) expressions. If a column is empty, the corresponding member is calculated normally. If the formula in the column is invalid, a run-time error occurs when a cell value using the member is retrieved.

Order of evaluation among dimensions with custom rollups is determined by the order of the dimensions in the Dimensions collection of the parent cube. Calculated members are always evaluated before custom rollups.

注意：

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 then the cube is considered to be invalid. Processing such a cube will raise a validation error with an error code of mderrInvalidCubeDistinctCountWithCustomRollups.
