TupleToStr (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 a Multidimensional Expressions (MDX)–formatted string that corresponds to a specified tuple.

TupleToStr(Tuple_Expression) 

Tuple_Expression

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

This function is used to transfer a string-representation of a tuple to an external function for parsing. The string that is returned is enclosed in braces {} and each member, if more than one is expressly defined in the tuple, is separated by a comma.

Examples

The following example returns the string ([Date].[Calendar Year].&[2001],[Geography].[Geography].[Country].&[United States]) :

WITH MEMBER Measures.x AS TupleToStr 
   ( 
      ([Date].[Calendar Year].&[2001]
         , [Geography].[Geography].[Country].&[United States]
      )
   )   
SELECT Measures.x ON 0
FROM [Adventure Works]

The following example returns the same string as the previous example.

WITH SET s AS 
   {
      ([Date].[Calendar Year].&[2001],
         [Geography].[Geography].[Country].&[United States]
      ) 
   }
MEMBER Measures.x AS TupleToStr ( s.Item(0) )
SELECT Measures.x ON 0
FROM [Adventure Works]
