具有多个标准的 MDX 案例陈述 "When"

Question

我正在尝试尽可能多地合并以下 MDX 脚本，想知道是否有办法将四个季度（Q1、Q2、Q3、Q4）合并为一行？另外，如果您对如何简化这个有任何进一步的想法，我洗耳恭听！

Case [Period].CurrentMember
  When [Q1] Then [Finance Charge and NSF Revenue] / ([CXO_Average Total A/R]+[Average Total A/R - Normalized Load])*4
  When [Q2] Then [Finance Charge and NSF Revenue] / ([CXO_Average Total A/R]+[Average Total A/R - Normalized Load])*4
  When [Q3] Then [Finance Charge and NSF Revenue] / ([CXO_Average Total A/R]+[Average Total A/R - Normalized Load])*4
  When [Q4] Then [Finance Charge and NSF Revenue] / ([CXO_Average Total A/R]+[Average Total A/R - Normalized Load])*4
  When [Total Year] Then [Finance Charge and NSF Revenue] / ([CXO_Average Total A/R]+[Average Total A/R - Normalized Load])        
Else 
  [Finance Charge and NSF Revenue] / ([CXO_Average Total A/R]+[Average Total A/R - Normalized Load])*12
End

Answer 1

这应该有效

Case 
  When [Period].CurrentMember =[Q1] or [Period].CurrentMember =[Q2] or [Period].CurrentMember =[Q3] or [Period].CurrentMember =[Q4]
  Then [Finance Charge and NSF Revenue] / ([CXO_Average Total A/R]+[Average Total A/R - Normalized Load])*4
   When [Period].CurrentMember =[Total Year] Then [Finance Charge and NSF Revenue] / ([CXO_Average Total A/R]+[Average Total A/R - Normalized Load])        
Else 
  [Finance Charge and NSF Revenue] / ([CXO_Average Total A/R]+[Average Total A/R - Normalized Load])*12
End

下面是另一个基于冒险作品的示例，对您有所帮助。

with member measures.test as 
case  
when 
[Product].[Subcategory].currentmember.Properties ("Member_Value",TYPED) ="caps" 
or [Product].[Subcategory].currentmember.Properties ("Member_Value",TYPED) ="chains" 
or [Product].[Subcategory].currentmember.Properties ("Member_Value",TYPED) ="gloves" 
then 1 
when [Product].[Subcategory].currentmember.Properties ("Member_Value",TYPED) ="Fenders" 
then 5
else 0 end 
select {[Measures].[Internet Sales Amount],measures.test} on columns ,
[Product].[Subcategory].[Subcategory] on rows 
from 
[Adventure Works]

Answer 2

IS 运算符是您的朋友：我不确定 = 运算符是否有效，使用 ....Properties ("Member_Value",TYPED) ="caps" 很慢。

我还尝试使用 IIF，在 MDX 中，它通常比 CASE

快

IIF(
      ( [Period].CURRENTMEMBER IS [Period].[Period].[Q1] ) 
   OR ( [Period].CURRENTMEMBER IS [Period].[Period].[Q1] ) 
   OR ( [Period].CURRENTMEMBER IS [Period].[Period].[Q1] ) 
   OR ( [Period].CURRENTMEMBER IS [Period].[Period].[Q1] ) 
   , DIVIDE(
         [Finance Charge and NSF Revenue]
        ,( [CXO_Average Total A/R]+[Average Total A/R - Normalized Load] )*4
     )
   , IIF(
        ( [Period].CURRENTMEMBER IS [Period].[Period].[Total Year] )
        , DIVIDE(
             [Finance Charge and NSF Revenue]
            ,( [CXO_Average Total A/R]+[Average Total A/R - Normalized Load] )
          )
        , DIVIDE(
             [Finance Charge and NSF Revenue]
            ,( [CXO_Average Total A/R]+[Average Total A/R - Normalized Load] )*12
          )
)

编辑

使用 IIF/IS 进行更复杂的查询会更快 - 这相当于 MoazRubs AdvWrks 脚本：

WITH 
MEMBER measures.test as 
IIF(   
  [Product].[Subcategory].currentmember IS  [Product].[Subcategory].[Caps]
  OR [Product].[Subcategory].currentmember IS  [Product].[Subcategory].[Chains] 
    OR [Product].[Subcategory].currentmember IS  [Product].[Subcategory].[Gloves] 
  , 1
    , IIF(
       [Product].[Subcategory].currentmember IS  [Product].[Subcategory].[Fenders] 
     ,5
         ,NULL
      )
) 
SELECT 
   {
        [Measures].[Internet Sales Amount],
            measures.test
        } ON 0,
[Product].[Subcategory].[Subcategory] ON 1 
FROM 
[Adventure Works]
