Question

我使用MDX代码来计算四分位数，就像在这个博客中一样： https://electrovoid.wordpress.com/2011/06/24/ssas-quartile/

这就是我在做的事情：

WITH SET OrderedData AS 
ORDER
    (    
        NONEMPTY
                (
                 [Dim Parameter].[id].[id]
                 *[Dim Result].[Id].[Id].ALLMEMBERS,
                 [Measures].[Value]
                ),  
        [Measures].[Value], 
        BASC
     )

MEMBER [Measures].[RowCount] AS COUNT (OrderedData)
MEMBER [Measures].[i25] AS ( .25 *  ( [RowCount] - 1 ) ) + 1
MEMBER [Measures].[i25Lo] AS FIX([i25])   - 1
MEMBER [Measures].[i25Rem] AS ([i25] - FIX([i25]))
MEMBER [Measures].[n25Lo] AS (OrderedData.Item([i25Lo]), [Value])
MEMBER [Measures].[n25Hi] AS (OrderedData.Item([i25Lo] + 1), [Value])
MEMBER [Measures].[Quartile1] AS [n25Lo] + ( [i25Rem] * ( [n25Hi] - [n25Lo] ))
,FORMAT_STRING='Currency'
MEMBER [Measures].[Quartile2] AS MEDIAN(OrderedData, [Value])
,FORMAT_STRING='Currency'
MEMBER [Measures].[i75] AS ( .75 *  ( [RowCount] - 1 ) ) + 1
MEMBER [Measures].[i75Lo] AS FIX([i75]) - 1
MEMBER [Measures].[i75Rem] AS ([i75] - FIX([i75]))
MEMBER [Measures].[n75Lo] AS (OrderedData.Item([i75Lo] ),[Value])
MEMBER [Measures].[n75Hi] AS (OrderedData.Item([i75Lo] + 1),[Value])
MEMBER [Measures].[Quartile3] AS [n75Lo] + ( [i75Rem] * ( [n75Hi] - [n75Lo] ))
,FORMAT_STRING='Currency'
MEMBER [Measures].[RIC] As ([Quartile3]-[Quartile1] )
MEMBER [Measures].[Ls] As ([Quartile3]+ ([RIC]*1.5) )
MEMBER [Measures].[Li] As ([Quartile1]- ([RIC] *1.5)) 
MEMBER [Measures].[MAX] as  MAX (Filter(OrderedData ,[value]<=[LS]),[value])
MEMBER [Measures].[Min] as  MIn(Filter(OrderedData ,[value]>=[Li]),[value])
MEMBER [Measures].[out] as  MAX (Filter(OrderedData ,[value]>[LS]),[value

我想要的是添加Dim日期，计算每个月的四分位数，如下所示：

MEMBER [Measures].[out] as MAX (Filter(OrderedData ,[value]>[LS]),[value

SELECT {
        [Measures].[Quartile1],[Measures].[Quartile2],[Measures].[Quartile3], [min],

        [MAX] , [out] , [Measures].[ValueAVG],[RowCount],[Measures].[Recuento Fact Result]
       } ON 0 , 
[Dim Parameter].[Reference].[Reference] * 
[Dim Parameter].[Section ES].[Section ES] * 
[Id Distribution Date].[DateJ].[Month] ON 1 
FROM [Tess Tek DW Dev]

但是它不起作用，如何只在一个mdx查询中计算不同日期范围的四分位数？

您需要以某种方式将日期纳入WITH语句。

首先尝试将目标月份（将在行上）添加到命名集合中：

WITH 
SET [TargetSet] AS
 {
  [Id Distribution Date].[DateJ].[Month].[Jan-2015],
  [Id Distribution Date].[DateJ].[Month].[Feb-2015]
 }

然后我会添加另一个将TargetSet考虑在内的集合：

SET [NonEmptyIds] AS
 NonEmpty(
    [Dim Parameter].[id].[id]
   *[Dim Result].[Id].[Id].ALLMEMBERS
  ,
  {[Measures].[Value]} * [TargetSet]
 )

然后将此集合提供给您当前的集合：

SET [OrderedData] AS 
ORDER
    (    
        [NonEmptyIds],  
        [Measures].[Value], 
        BASC
     )

然后尝试修改行代码段以使用TargetSet：

[Dim Parameter].[Reference].[Reference] * 
[Dim Parameter].[Section ES].[Section ES] * 
[TargetSet] ON 1
