LinkMember (MDX)

Topic Status: Some information in this topic is preview and subject to change in future releases. Preview information describes new features or changes to existing features in Microsoft SQL Server 2016 Community Technology Preview 2 (CTP2).

Returns the member equivalent to a specified member in a specified hierarchy.

LinkMember(Member_Expression, Hierarchy_Expression) 

Member_Expression

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

Hierarchy_Expression

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

The LinkMember function returns the member from the specified hierarchy that matches the key values at each level of the specified member in a related hierarchy. Attributes at each level must have the same key cardinality and data type. In unnatural hierarchies, if there is more than one match for an attribute's key value, the result will be an error or indeterminate.

Examples

The following example uses the LinkMember function to return the default measure in the Adventure Works cube for the ascendants of the July 1, 2002 member of the Date.Date attribute hierarchy in the Calendar hierarchy.

SELECT  Hierarchize
   (Ascendants 
      (LinkMember 
         ([Date].[Date].[July 1, 2002], [Date].[Calendar]
         )
       )
    ) ON 0
FROM [Adventure Works]
