Question

我有两个想要加入的查询，这会给我计算行的总数。我遇到的问题是虽然措施来自1个事实表，但是Squad名称有两个角色扮演维度。我对MDX非常陌生。

结果将类似于

 | Competition    | Squad   | Goals A | Goals B | Total (Goals A + Goals B)|
 |----------------|---------|---------|---------|--------------------------|
 | Premier League | Arsenal | 25      | 15      | 40                       |

提前致谢。

Answer 1

您可以尝试这样的事情：

WITH MEMBER [Measures].[Goals B Linked]
AS (LinkMember([Squad A].[Squad Name].CurrentMember, [Squad B].[Squad Name]), [Measures].[Goals B]),
MEMBER [Measures].[Total]
AS [Measures].[Goals A] + [Measures].[Goals B Linked]

SELECT 
{[Measures].[Goals A], [Measures].[Goals B Linked], [Measures].[Total]}  ON COLUMNS,
NON EMPTY ([Dim Competition].[Hierarchy].[Competition ID],[Squad A].[Squad Name].ALLMEMBERS) ON ROWS
FROM 
[FDC Star]
WHERE [Dim Competition].[Competition ID].&[1];

Answer 2

在花了很多时间试图找到解决方案后，我终于解决了我的问题。

由于

    WITH  
    MEMBER [Measures].[GFA] AS 
    (
    ([Measures].[Goals A]),
    linkmember([Dim Squad].[Squad Name],[Squad A].[Squad Name]),
    root([Squad Name])
    )
    MEMBER [Measures].[GFB] AS 
    (
    ([Measures].[Goals B]),
    linkmember([Dim Squad].[Squad Name],[Squad B].[Squad Name]),
    root([Squad Name])
    )
    MEMBER [MEASURES].[GF] AS
    (
        [Measures].[GFA] + [Measures].[GFB]
    )
    select 
    {[Measures].[GFA],[Measures].[GFB],[MEASURES].[GF]} on 0,
    non empty [Dim Squad].[Squad Name].allmembers on 1
    from [FDC Star]
    where [Dim Competition].[Competition ID].&[1]

MDX在两个角色扮演维度中添加了两个立方体度量
