Question

我可以通过使用下面的逻辑设置老化存储桶来创建老化存储桶，尽管查询运行存储桶都会返回空白。我最初使用了一些使用lag的逻辑，但发现lag计算的是成员级别而不是实际天数。我在这里缺少什么？

WITH


member [0-30] as ( IIF (Datediff("d", [TXN].[Age Date], STRTOMEMBER(@ToDOSDate,CONSTRAINED) ) >=0 AND Datediff("d", [TXN].[Age Date], STRTOMEMBER(@ToDOSDate,CONSTRAINED) ) <= 30
 , [measures].[charge_amount] , 0) 
)

member [31-60] as ( IIF(Datediff('d', [TXN].[Age Date], STRTOMEMBER(@ToDOSDate,CONSTRAINED) ) >=31 AND Datediff('d', [TXN].[Age Date], STRTOMEMBER(@ToDOSDate,CONSTRAINED) ) <= 60 
,[measures].[charge_amount], 0 ) 
)

member [61-90] as ( IIF(Datediff("d", [TXN].[Age Date], STRTOMEMBER(@ToDOSDate,CONSTRAINED) ) >=61 AND Datediff("d", [TXN].[Age Date], STRTOMEMBER(@ToDOSDate,CONSTRAINED) ) <= 90 
,[measures].[charge_amount], 0 ) 
)

member [91-120] as ( IIF(Datediff("d", [TXN].[Age Date], STRTOMEMBER(@ToDOSDate,CONSTRAINED) ) >=91 AND Datediff("d", [TXN].[Age Date], STRTOMEMBER(@ToDOSDate,CONSTRAINED) ) <= 120 
,[measures].[charge_amount], 0 ) 
)

member [120+] as ( IIF(Datediff("d", [TXN].Age Date], STRTOMEMBER(@ToDOSDate,CONSTRAINED) ) >= 120 
,[measures].[ charge_amount], 0 ) 
)

我假设：

您的[TXN].[Age Date]子句中有SELECT ON ROWS。
@ToDOSDate是正确的，并且您已经完全测试了它在进入STRTOMEMBER(@ToDOSDate,CONSTRAINED)时是否正常工作。

Datediff是一个vba函数，需要 date 类型的数据作为它的参数 - 你输入的是成员类型的数据。

我要做的另一个假设是，层次结构Name成员的[TXN].[Age Date]属性的格式被设置为被解释为日期。然后，您可以执行以下操作：

WITH
  MEMBER [Measures].[0-30] AS 
      IIF (
       Datediff(
          "d" 
         ,[TXN].[Age Date].CURRENTMEMBER.NAME
         ,STRTOMEMBER(@ToDOSDate,CONSTRAINED).NAME 
       ) >=0 
       AND 
       Datediff(
          "d"
         ,[TXN].[Age Date].CURRENTMEMBER.NAME
         ,STRTOMEMBER(@ToDOSDate,CONSTRAINED).NAME  
       ) <= 30
    , [measures].[charge_amount] 
    , NULL)

使用MDX的老化桶
