Question

我正在处理MDX查询。我希望其中一列的值根据另一列的值动态更改。所以我写的查询是： -



WITH 
MEMBER  [Measures].[FName]  AS [Loyalty Cards].[Grouped    Cards].CurrentMember.Properties("Full Name")
MEMBER  [Measures].[RegShop]AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("Reg Shop")
MEMBER  [Measures].[Date Of First Bet] AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("First Use Date")
MEMBER  [Measures].[MostUsedShop] AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("Most Used Shop")
MEMBER  [Measures].[Givex_mem_Num]AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("KeyCardNumbers")


 SELECT {
 [Measures].[Givex_mem_Num]
 ,[Measures].[FName]
 ,[Measures].[RegShop]
 ,[Measures].[Date Of First Bet]
 ,[Measures].[MostUsedShop]
 ,[Measures].[Slip Count]
 ,[Measures].[Slip Stake]
 ,[Measures].[SlipGrossWin]
 ,[Measures].[Average Stake Per Slip]
 }ON COLUMNS,
 {
   NONEMPTY([Loyalty Cards].[Grouped Cards].[KeyCardNumbers], [Measures].[Total     Turnover])
 }
  ON ROWS
  FROM [RetailCube]
  WHERE 
  [Time Slice].[Timeslice].[TimesliceID].&[LIVE2DT]

WITH MEMBER [Measures].[FName] AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("Full Name") MEMBER [Measures].[RegShop]AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("Reg Shop") MEMBER [Measures].[Date Of First Bet] AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("First Use Date") MEMBER [Measures].[MostUsedShop] AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("Most Used Shop") MEMBER [Measures].[Givex_mem_Num]AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("KeyCardNumbers") SELECT { [Measures].[Givex_mem_Num] ,[Measures].[FName] ,[Measures].[RegShop] ,[Measures].[Date Of First Bet] ,[Measures].[MostUsedShop] ,[Measures].[Slip Count] ,[Measures].[Slip Stake] ,[Measures].[SlipGrossWin] ,[Measures].[Average Stake Per Slip] }ON COLUMNS, { NONEMPTY([Loyalty Cards].[Grouped Cards].[KeyCardNumbers], [Measures].[Total Turnover]) } ON ROWS FROM [RetailCube] WHERE [Time Slice].[Timeslice].[TimesliceID].&[LIVE2DT]

我从上面得到的样本输出是： -

现在我希望第一个投注列的日期根据Givex_mem_num的值进行更改（特别是对于第一行，它是= -99）。任何人都可以帮我解决这个问题吗？我尝试了几种方法。

直到最新我修改了我的查询的第一部分： -


      WITH 
      MEMBER  [Measures].[FName]  AS [Loyalty Cards].[Grouped    Cards].CurrentMember.Properties("Full Name")
      MEMBER  [Measures].[RegShop]AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("Reg Shop")
      MEMBER  [Measures].[NullVal] AS NULL
      MEMBER  [Measures].[Date Of First Bet] AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("First Use Date")
      MEMBER  [Measures].[MostUsedShop] AS [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("Most Used Shop")
      MEMBER  [Measures].[Givex_mem_Num]AS 
       (
       IIF( [Loyalty Cards].[Grouped Cards].CurrentMember.Properties("KeyCardNumbers")=-99,[Measures].[Date Of First Bet] ='A',[Measures].[Date Of First Bet])
        )

   SELECT {
 [Measures].[Givex_mem_Num]
,[Measures].[FName]
,[Measures].[RegShop]
,[Measures].[Date Of First Bet]
,[Measures].[MostUsedShop]
,[Measures].[Slip Count]
,[Measures].[Slip Stake]
,[Measures].[SlipGrossWin]
,[Measures].[Average Stake Per Slip]
}ON COLUMNS,

但是这会将Givex_mem_num值更改为第一次下注日期的值，而不需要。如果您需要更多详细信息，请发表评论

Answer 1

您可以在WITH MEMBER子句中定义单个成员的值，但不能更改其他成员。您应该将另一个成员添加到WITH子句中，如

MEMBER [Measures].[Calc Date Of First Bet] AS
       IIf([Measures].[Givex_mem_Num] = -99, 'A', [Measures].[Date Of First Bet])

然后在列的度量列表中使用该成员而不是[Measures].[Date Of First Bet]。当然，您可以按照自己的意愿重命名，它应该与所有现有的度量名称不同。
