MDX - How to select one column and sort the returned data

Question

For a SSRS report, I'm trying to return a list of sorted data from a dimension to use with a parameter.

My dimension is [Radio].[Radio NO].[Radio NO] where the last Radio NO is a string.

I can find examples of returning one column while sorting on another but I can't figure out how to sort and return just one column.

Answer 1

Without seeing the exact structure of your cube / query an avenue you could explore, if you'd like to order alphabetical, is the following

ORDER(
   [Radio].[Radio NO].[Radio NO].MEMBERS
  ,[Radio].[Radio NO].CURRENTMEMBER.MEMBER_CAPTION
  ,BDESC
)

If you want to order by a measure in your cube, then something like the following:

ORDER(
   [Radio].[Radio NO].[Radio NO].MEMBERS
  ,[Measures].[Profit]
  ,BDESC
)

This is a possible if you really need to change the column name before hitting SSRS but it has the disadvantage of changing it to a measure:

WITH 
MEMBER [Measures].[thisIsTheNewName] AS
  [Radio].[Radio NO].CURRENTMEMBER.MEMBER_CAPTION
SELECT 
{[Measures].[thisIsTheNewName]} ON COLUMNS,
ORDER(
   [Radio].[Radio NO].[Radio NO].MEMBERS
  ,[Radio].[Radio NO].CURRENTMEMBER.MEMBER_CAPTION
  ,BASC
) On ROWS
FROM [OurCube];

Answer 2

Thanks whytheq! Based on your answer, here's what I came up with that works:

SELECT {} ON COLUMNS,
ORDER(
   [Radio].[Radio NO].[Radio NO].MEMBERS
  ,[Radio].[Radio NO].CURRENTMEMBER.MEMBER_CAPTION
  ,BASC
) On ROWS
  FROM [OurCube]
