Ssas 对复集排序

我一直在玩Chris Webb在这里发现的剧本：

改编剧本如下：

WITH 
  SET MyMonths AS 
    TopPercent
    (
      [Date].[Calendar].[Month].MEMBERS
     ,20
     ,[Measures].[Reseller Sales Amount]
    ) 
  SET MyEmployees AS 
    [Employee].[Employee].[Employee].MEMBERS 
  SET MyMonthsWithEmployeesSets AS 
    Generate
    (
      MyMonths
     ,Union
      (
        {[Date].[Calendar].CurrentMember}
       ,StrToSet
        ("
         Intersect({}, 
         {TopCount(MyEmployees, 10, ([Measures].[Reseller Sales Amount],[Date].     [Calendar].CurrentMember))
         as EmployeeSet"
            + 
              Cstr(MyMonths.CurrentOrdinal)
          + "})"
        )
      )
    ) 
  MEMBER [Employee].[Employee].[RestOfEmployees] AS 
    Aggregate
    (
      Except
      (
        MyEmployees
       ,StrToSet
        (
          "EmployeeSet" + Cstr(Rank([Date].[Calendar].CurrentMember,MyMonths))
        )
      )
    ) 
  MEMBER [Measures].[EmployeeRank] AS 
    Rank
    (
      [Employee].[Employee].CurrentMember
     ,StrToSet
      (
        "EmployeeSet" + Cstr(Rank([Date].[Calendar].CurrentMember,MyMonths))
      )
    ) 
SELECT 
  {
    [Measures].[EmployeeRank]
   ,[Measures].[Reseller Sales Amount]
  } ON 0
 ,Hierarchize
  (
    Union
    (
      Filter
      (
        MyMonthsWithEmployeesSets * MyEmployees   //<<<HERE<<<<
       ,
        [Measures].[EmployeeRank] >= 1
      )
     ,{
        MyMonthsWithEmployeesSets * [Employee].[Employee].[RestOfEmployees]
      }
    )
  ) ON 1
FROM [Adventure Works];

这样做会导致以下错误消息：

解析字符串[EmployeeSet0]时，多维数据集中找不到维度“[EmployeeSet0]”

我认为这是因为度量值

EmployeeRank

使用了在generate函数中创建的内联集。

如果您将

EmployeeRank

的

restofeployees

重新定义为11，您只需将该成员添加到

Filter

的第一个参数集中，然后应用

顺序

，由于它将在位置1到10后排序：

WITH 
  SET MyMonths AS 
    TopPercent
    (
      [Date].[Calendar].[Month].MEMBERS
     ,20
     ,[Measures].[Reseller Sales Amount]
    ) 
  SET MyEmployees AS 
    [Employee].[Employee].[Employee].MEMBERS 
  SET MyMonthsWithEmployeesSets AS 
    Generate
    (
      MyMonths
     ,Union
      (
        {[Date].[Calendar].CurrentMember}
       ,StrToSet
        ("
         Intersect({}, 
         {TopCount(MyEmployees, 10, ([Measures].[Reseller Sales Amount],[Date].     [Calendar].CurrentMember))
         as EmployeeSet"
            + 
              Cstr(MyMonths.CurrentOrdinal)
          + "})"
        )
      )
    ) 
  MEMBER [Employee].[Employee].[RestOfEmployees] AS 
    Aggregate
    (
      Except
      (
        MyEmployees
       ,StrToSet
        (
          "EmployeeSet" + Cstr(Rank([Date].[Calendar].CurrentMember,MyMonths))
        )
      )
    ) 
  MEMBER [Measures].[EmployeeRank] AS 
    IIF([Employee].[Employee].CurrentMember IS [Employee].[Employee].[RestOfEmployees], 
        11,
        Rank
        (
          [Employee].[Employee].CurrentMember
         ,StrToSet
          (
            "EmployeeSet" + Cstr(Rank([Date].[Calendar].CurrentMember,MyMonths))
          )
        ) 
    )
SELECT 
  {
    [Measures].[EmployeeRank]
   ,[Measures].[Reseller Sales Amount]
  } ON 0
 ,
   Order(
      Filter
      (
        MyMonthsWithEmployeesSets  
          * UNION(MyEmployees, {[Employee].[Employee].[RestOfEmployees]})
       ,
        [Measures].[EmployeeRank] >= 1
      ), [Measures].[EmployeeRank]
      )

+1个非常有趣的答案（和问题）。我发现这项技术几乎像魔术一样，1上的

部分说
MyMonthWithEmployeesSets*（MyEmployees…
很难理解，因为集合
MyMonthWithEmployeesSets
是几个月与空集合交叉的集合（前10名与{}合并），然而，
MyEmployees
是所有的雇员-我不容易想象。有什么想法可以帮助我理解吗？！@whytheq说实话，我没有试图理解长篇大论的所有细节。我只是试图解决这个问题。@FrankPI-非常明智-这让我更接近某种MDX紧张崩溃。@FrankPI…嘿
LOL
…你使用了
+
操作符：我要编辑。@whytheq我想你指的是我在回答这个问题最后的评论：我不想说我总是喜欢写
Union
，而不是
+
。我只是想表达我的观点，那是一个语言设计决策如果由我来决定的话，我会采取不同的做法。然而，既然语言设计是这样，我就照样使用它。
