这很好用：

WITH 
  SET [AllCountries] AS [Country].[Country].MEMBERS 
  SET [AllStates]    AS [State-Province].[State-Province].MEMBERS 
  SET [Top2States] AS 
    Generate
    (
      [AllCountries]
     ,TopCount
      (
        (EXISTING 
          [AllStates])
       ,3
       ,[Measures].[Internet Order Count]
      )
    ) 
  MEMBER [State-Province].[All].[RestOfCountry] AS 
    Aggregate({(EXISTING {[AllStates]} - [Top2States])}) 
SELECT 
  {[Measures].[Internet Order Count]} ON COLUMNS
 ,{
      [AllCountries]
    * 
      {
        [State-Province].[All]
       ,[Top2States]
       ,[State-Province].[All].[RestOfCountry]
      }
  } ON ROWS
FROM [Adventure Works];

EXISTING关键字有很多帮助。

如果两个层次结构ON ROWS不是来自同一维度，就像上面的国家和州一样，那么我们会有以下内容：

WITH 
  SET [AllCountries] AS [Country].[Country].MEMBERS 
  SET [AllCats]      AS [Product].[Category].[Category].MEMBERS 
  SET [Top5Cats] AS 
    Generate
    (
      [AllCountries]
     ,TopCount
      (
        (EXISTING 
          [AllCats])
       ,5
       ,[Measures].[Internet Order Count]
      )
    ) 
  MEMBER [Product].[Category].[All].[RestOfProds] AS 
    Aggregate({(EXISTING {[AllCats]} - [Top5Cats])}) 
SELECT 
  {[Measures].[Internet Order Count]} ON COLUMNS
 ,{
      [AllCountries]
    * 
      {
        [Product].[Category].[All]
       ,[Top5Cats]
       ,[Product].[Category].[All].[RestOfCountry]

      }
  } ON ROWS
FROM [Adventure Works];

您可以在上面的结果中看到，针对每个国家/地区重复相同的类别集，顺序相同，即引擎未找到每个国家/地区的topCount。 EXISTING现在是多余的。

我们如何调整上面的第二个脚本，使其具有与顶级脚本类似的功能？

修改

更好的例子是以下使用Product。好像引擎正在为所有国家/地区找到TopCount，然后针对每个国家/地区设置相同的设置。我希望每个国家/地区TopCount：

WITH 
  SET [AllCountries] AS 
    [Country].[Country].MEMBERS 
  SET [AllProds] AS 
    [Product].[Product].[Product].MEMBERS 
  SET [Top5Prods] AS 
    Generate
    (
      [AllCountries]
     ,TopCount
      (
        (EXISTING 
          [AllProds])
       ,5
       ,[Measures].[Internet Order Count]
      )
    ) 
  MEMBER [Product].[Product].[All].[RestOfProds] AS 
    Aggregate({(EXISTING {[AllProds]} - [Top5Prods])}) 
SELECT 
  {[Measures].[Internet Order Count]} ON COLUMNS
 ,NON EMPTY 
    {
        [AllCountries]
      * 
        {
          [Product].[Product].[All]
         ,[Top5Prods]
         ,[Product].[Product].[All].[RestOfProds]
        }
    } ON ROWS
FROM [Adventure Works];

EDIT2

这是Sourav创意的最新版本 - 遗憾的是RestOfProds成员无法正常运作：

WITH 
  SET [AllCountries] AS 
    [Country].[Country].MEMBERS 
  SET [AllProds] AS 
    [Product].[Product].[Product].MEMBERS 
  SET [Top5Prods] AS

             ,[Product].[Product].[All]
            )
          + 
            //The top x prods

              )
             ,5
             ,[Measures].[Internet Sales Amount]
            )
        }
    ) 
  SET [RestOfProds] AS 
    Extract

以下内容具有正确的顺序，以便成员RestOfProds始终遵循相应的前5名

Answer 1

在命名集上使用时，

EXISTING并没有什么区别，因为在布置轴成员之前创建了命名集。在你的情况下，GENERATE实际上只是创建静态集，然后在轴上一切都只是交叉连接。

要使TopCount脚本正常工作，您需要处理一组中的所有cross joins，以便一起评估所有内容。我不确定，但您可以尝试下面的内容：

WITH 
  SET [AllCountries] AS [Country].[Country].MEMBERS 
  SET [AllCats]    AS [Product].[Category].[Category].MEMBERS 
  SET [Top5Cats] AS 
    Generate
    (
      [AllCountries] as a
     ,
     {
     (a.current , [Product].[Category].[All] ) //The ALL member
     +   
     TopCount  //The top 2 categories
      (
        NonEmpty((a.current * [AllCats] ) , (a.CURRENT, [Measures].[Internet Order Count]))
       ,2
       ,[Measures].[Internet Order Count]      
      ) 
      }
    + 
    { //The rest of the members
    a.current * [AllCats] 
    - 
    a.current *{     
     TopCount
      (
        NonEmpty([AllCats] , (a.CURRENT, [Measures].[Internet Order Count]))
       ,2
       ,[Measures].[Internet Order Count]      
      ) 
      }
      }
    )

  MEMBER [Product].[Category].[All].[RestOfProds] AS 
    Aggregate({(EXISTING {[AllCats]} - [Top5Cats])}) 

SELECT 
  {[Measures].[Internet Order Count]} ON COLUMNS,
[Top5Cats] ON ROWS
FROM [Adventure Works];

修改如果您需要RestOfCats成员，则可以添加此代码。

SET [RestOfCats] AS EXTRACT ( { [AllCountries] * [AllCats] - [Top5Cats] }, [Product].[Category] ) MEMBER [Product].[Category].[All].[RestOfCats] AS Aggregate([RestOfCats])

编辑2

继续您的示例，在定义中另外删除“All”成员。

SET [RestOfProds] AS Extract ( {[AllCountries] * [AllProds]} - [Top5Prods] - [AllCountries]*[Product].[Product].[All] ,[Product].[Product] )

Answer 2

如果要在同一维度中交叉连接多个层次结构，则仅显示有效组合。这称为自动存在，它解释了为什么第一个查询的工作方式与您想要的一样。

当交叉连接来自不同维度的层次结构时，不会发生自动存在。我认为这解释了第二个查询中返回的奇数组合。

尝试在ON ROWS定义的开头添加NON EMPTY。然后它将只返回具有互联网订单计数度量值的组合（列上的任何度量）。这是限制交叉连接的正确方法。

如果您不想在互联网订单计数上使用非空，那么您需要在不同的度量上使用NonEmpty（，[Measures]。[A Different Measure]）？

编辑：看起来该问题与自动存在无关，但与每个国家/地区执行不同的TopCount有关。所以这个信息可以帮助别人，但不是这个问题的答案。

这似乎工作正常：

WITH 
  SET [AllCountries] AS 
    [Country].[Country].MEMBERS 
  SET [AllProds] AS 
    [Product].[Product].[Product].MEMBERS 
  SET [Top5Prods] AS 
    Generate
    (
      [AllCountries] AS a
     ,{
          (
            a.CurrentMember
           ,[Product].[Product].[All]
          )
        + 
            //The top x prods
            a.CurrentMember
          * 
            TopCount
            (
              [AllProds]
             ,5
             ,[Measures].[Internet Sales Amount]
            )
      }
    ) 
  MEMBER [Product].[Product].[All].[Other Products] AS 
    Aggregate
    (
        [Country].CurrentMember * [Product].[Product].[Product].MEMBERS
      - 
        [Top5Prods]
    ) 
SELECT 
  {[Measures].[Internet Sales Amount]} ON COLUMNS
 ,Hierarchize(
    {
     [Top5Prods]
    ,[AllCountries] * [Product].[Product].[All].[Other Products]
    }
) ON ROWS
FROM [Adventure Works];
