Question

我有MDX显示过去4个月内特定广告名称的衡量标准：

WITH 
  SET [Selected Measures] AS 
    {
      [Measures].[Cost]
     ,[Measures].[Clicks]
    } 
SELECT 
  [Selected Measures] ON COLUMNS
 ,NonEmpty
  (
    (
      [Ad Name Dim].[Ad Name].[Name].ALLMEMBERS
     ,
        ClosingPeriod
        (
          [Time Dim].[Time Dim].[Month]
         ,[Time Dim].[Time Dim].[All Time]
        ).Lag(3)
      : 
        ClosingPeriod
        (
          [Time Dim].[Time Dim].[Month]
         ,[Time Dim].[Time Dim].[All Time]
        )
    )
  ) ON ROWS
FROM [CubeName];

我想在SSRS报告中添加另一个可供我使用的字段，该字段将显示特定广告在数据上的第一个日期

像 Min（[Time Dim]。[Time Dim]。[Day]）。

Answer 1

这个（未经测试）：

With SET [Selected Measures] AS { [Measures].[Cost]
                            ,[Measures].[Clicks]  } 

SET SetOfMonths as ClosingPeriod([Time Dim].[Time Dim].[Month], 
[Time Dim].[Time Dim].[All Time]).Lag(3):ClosingPeriod([Time Dim].[Time Dim].[Month])

SET FirstDay as
HEAD([Time Dim].[Time Dim].[Day], 1)

SELECT  [Selected Measures]  ON COLUMNS,
nonempty(([Ad Name Dim].[Ad Name].[Name].allmembers,
SetOfMonths, FirstDay,     
[Time Dim].[Time Dim].[All Time])) ON ROWS
FROM [CubeName]

Answer 2

未经测试 - 如果您可以转换为针对AdvWorks多维数据集的脚本，那么对于贡献者来说更容易：

WITH 
  SET [Selected Measures] AS 
    {
      [Measures].[Cost]
     ,[Measures].[Clicks]
    } 
  MEMBER [Measures].[MinDate] AS 
    Head
    (
      NonEmpty
      (
        [Time Dim].[Time Dim].[Month] //<<to return minimum month but could be changed to a different level
       ,(
          [Selected Measures]
         ,[Ad Name Dim].[Ad Name].CurrentMember
        )
      )
     ,1
    ).Item(0).Item(0).Member_Caption 
SELECT 
  {
    [Selected Measures]
   ,[Measures].[MinDate]
  } ON COLUMNS
 ,NonEmpty
  (
    (
      [Ad Name Dim].[Ad Name].[Name].ALLMEMBERS
     ,
        ClosingPeriod
        (
          [Time Dim].[Time Dim].[Month]
         ,[Time Dim].[Time Dim].[All Time]
        ).Lag(3)
      : 
        ClosingPeriod
        (
          [Time Dim].[Time Dim].[Month]
         ,[Time Dim].[Time Dim].[All Time]
        )
    )
  ) ON ROWS
FROM [CubeName];

如何在MDX中添加第三个维度？
