屬性值

型別：System. . :: . .String
A String containing the MDX expression that is used to aggregate values for a Measure.

備註

Calculated measures use MDX expressions to supply their values, instead of binding to columns in a data source. The Expression property contains the MDX expression used to supply the values for a Measure only if the Measure is a calculated measure. Otherwise, this property contains an empty string ("").

The value of this property is identical to the value of the EXPRESSION column of the MEASURES schema rowset for the specified measure.
