Ascendants (MDX)

THIS TOPIC APPLIES TO:yesSQL Server (starting with 2008)noAzure SQL DatabasenoAzure SQL Data Warehouse noParallel Data Warehouse

Returns the set of the ascendants of a specified member, including the member itself.

Syntax


Ascendants(Member_Expression)  

Arguments

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

Remarks

The Ascendants function returns all of the ancestors of a member from the member itself up to the top of the member’s hierarchy; more specifically, it performs a post-order traversal of the hierarchy for the specified member, and then returns all ascendant members related to the member, including itself, in a set. This is in contrast to the Ancestor function, which returns a specific ascendant member, or ancestor, at a specific level.

Examples

The following example returns the count of reseller orders for the [Sales Territory].[Northwest] member and all the ascendants of that member from the Adventure Works cube. The Ascendants function constructs the set that includes the [Sales Territory].[Northwest] member and its ascendants for the ROWS axis.

SELECT  
   Measures.[Reseller Order Count] ON COLUMNS,  
   Order(  
      Ascendants(  
         [Sales Territory].[Northwest]  
      ),  
      DESC  
   ) ON ROWS  
FROM  
   [Adventure Works]
