Tail (MDX)

Returns a subset from the end of a set.

Syntax

  
Tail(Set_Expression [ ,Count ] )

Arguments

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

Count
A valid numeric expression that specifies the number of tuples to be returned.

Remarks

The Tail function returns the specified number of tuples from the end of the specified set. The order of elements is preserved. The default value of Count is 1. If the specified number of tuples is less than 1, the function returns the empty set. If the specified number of tuples exceeds the number of tuples in the set, the function returns the original set.

Example

The following example returns the Reseller Sales Measure for the top five selling subcategories of products, irrespective of hierarchy, based on Reseller Gross Profit. The Tail function is used to return only the last five sets in the result after the result is reverse-ordered using the Order function.

SELECT Tail  
   (Order   
      ([Product].[Product Categories].[SubCategory].members  
         ,[Measures].[Reseller Gross Profit]  
         ,BASC  
      )  
   ,5  
   ) ON 0  
FROM [Adventure Works]
