MDX query using ORDER and UNION functions

  • Here is my base query, and corresponding output, that I would like to order by year num, month name, and then faculty name. Basically, I want the output to look like the following;

    2007 January Faculty nnn

    2007 January User nnn

    2007 February Faculty nnn

    2007 February User nnn

    ...etc.

    Please note that duplicate year and month names are desired, as are the nulls in the output. The year and month matrix is defined by input date parameters which may not occur on the first of the month. They still want the data aggregated on year/month boundaries. Additionally, retention of dupes across Faculty and User could occur and need to be retained.

    My problem is that I can't seem to get the ORDER function working in conjunction with the UNION function. I tried wrapping the UNION function with the ORDER function, and also embedding the ORDER function within the UNION function. Both scenarios give me errors.

    Is there something simple that I have overlooked?

    ----- base query ------

    SELECT { [Measures].[Fact Email Count] } ON COLUMNS,

    union ( {([Dim Date].[year num].[year num], [Dim Date].[Month Name].[Month Name],

    [Dim Domain Course User].[Faculty Name].&[User])},

    {([Dim Date].[year num].[year num], [Dim Date].[Month Name].[Month Name],

    [Dim Domain Course User].[Faculty Name].&[Faculty])} ,all)

    DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS

    FROM ( SELECT ( { [Dim Domain Course User].[Domain Name].[dom1] } ) ON COLUMNS

    FROM ( SELECT ( {[Dim Date].[20070120]:[Dim Date].[20070515]} ) ON COLUMNS

    FROM [ANGEL74DW]))

    WHERE ( IIF( STRTOSET("dom1", CONSTRAINED).Count = 1, STRTOSET("dom1", CONSTRAINED),

    [Dim Domain Course User].[Domain Name].currentmember )

    )

    CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS;

    ----- current output -----

    Here is the query, and the error message when wrapping the UNION with the ORDER function;

    SELECT { [Measures].[Fact Email Count] } ON COLUMNS,

    order (

    union ( {([Dim Date].[year num].[year num], [Dim Date].[Month Name].[Month Name],

    [Dim Domain Course User].[Faculty Name].&[User])},

    {([Dim Date].[year num].[year num], [Dim Date].[Month Name].[Month Name],

    [Dim Domain Course User].[Faculty Name].&[Faculty])} ,all)

    , asc)

    DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS

    FROM ( SELECT ( { [Dim Domain Course User].[Domain Name].[dom1] } ) ON COLUMNS

    FROM ( SELECT ( {[Dim Date].[20070120]:[Dim Date].[20070515]} ) ON COLUMNS

    FROM [ANGEL74DW]))

    WHERE ( IIF( STRTOSET("dom1", CONSTRAINED).Count = 1, STRTOSET("dom1", CONSTRAINED),

    [Dim Domain Course User].[Domain Name].currentmember )

    )

    CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS;

    Query (7, 5) An expression was expected for the function argument and no expression was detected.

    According to BOL, the UNION returns a set, so why doesn't this work?

  • I got it figured out. Here is the updated query and the results. Thanks for looking.

    SELECT { [Measures].[Fact Email Count] } ON COLUMNS,

    order (

    union ( {([Dim Date].[year num].[year num], [Dim Date].[Month Name].[Month Name],

    [Dim Domain Course User].[Faculty Name].&[User])},

    {([Dim Date].[year num].[year num], [Dim Date].[Month Name].[Month Name],

    [Dim Domain Course User].[Faculty Name].&[Faculty])} ,all),

    settostr({([Dim Date].[year num], [Dim Date].[Month Name],

    [Dim Domain Course User].[Faculty Name])}), asc)

    DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS

    FROM ( SELECT ( { [Dim Domain Course User].[Domain Name].[dom1] } ) ON COLUMNS

    FROM [ANGEL74DW]))

    WHERE ( IIF( STRTOSET("dom1", CONSTRAINED).Count = 1, STRTOSET("dom1", CONSTRAINED),
