DefaultMember (MDX)

Returns the default member of a hierarchy.



A valid Multidimensional Expressions (MDX) expression that returns a hierarchy.

The default member on an attribute is used to evaluate expressions when an attribute is not included in a query.


The following example uses the DefaultMember function, in conjunction with the Name function, to return the default member for the Destination Currency dimension in the Adventure Works cube. The example returns US Dollar. The Name function is used to return the name of the measure rather than the default property of the measure, which is value.

WITH MEMBER Measures.x AS 
   [Destination Currency].[Destination Currency].DefaultMember.Name
SELECT Measures.x ON 0
FROM [Adventure Works]
