Mdx 某些属性的TOPCOUNT查询结果不正确

我试图找出哪一年是该州各省经销商销售额最高的一年。我正在使用AdventureWorksDW2008R2数据库

这是我得到的问题-

SELECT { [Reseller Sales Amount] } ON COLUMNS,
{
  Generate (
    [Geography].[Geography].[Country].Members,
    TopCount (
      Order (
        Descendants ( 
           [Geography].[Geography].CurrentMember
         , [Geography].[Geography].[State-Province] 
        ) 
       *[Date].[Calendar].[Calendar Year].Members,
        [Reseller Sales Amount],
        DESC
      ),
      1
    )
  )
} ON ROWS
FROM [Adventure Works]

---

在法国，它将（null）显示为结果集。还有，为什么它没有列出所有的州省份，而只是选择其中的几个？是否也有可能让国家与结果并驾齐驱。当我尝试另一个交叉连接时，我得到一个错误，说地理层次结构已经存在。

要消除空值，可以使用

BDESC

而不是

DESC

。额外的

B

意味着所有自然的层次结构顺序都将被打破

SELECT { [Reseller Sales Amount] } ON COLUMNS,
{
  Generate (
    [Geography].[Geography].[Country].Members,
    TopCount (
      Order (
        Descendants ( 
           [Geography].[Geography].CurrentMember
         , [Geography].[Geography].[State-Province] 
        ) 
       *[Date].[Calendar].[Calendar Year].Members,
        [Reseller Sales Amount],
        BDESC //<<< 
      ),
      1
    )
  )
} ON ROWS
FROM [Adventure Works];

结果如下：

我们将探讨顶级过滤器在级别上的通用选项实现

可以为每个级别设置顶级规则

它用于数据的详细分析（展开、向下展开）

骨料基于顶部形成

只要数据按顺序排序，设置排序顺序就可以了 大多数数据透视表

（上）使用一个我们都可以玩的立方体，提出了一个很好的问题。感谢whytheq给出了解释清楚的答案。我只是想知道是否不可能使用相同的用户层次结构并获得结果？事情是在我们拥有的多维数据集中，非用户定义的属性被隐藏了。我需要使用子多维数据集来查询吗？我对MDX不是很熟悉。@VKarthik在select子句中不能多次使用同一层次结构-这是MDX的规则。我在过去也遇到过类似的问题——我们的多维数据集设计者将属性层次结构隐藏起来，因为他认为它“更整洁”——现在它们被取消隐藏，并放置在每个维度内的文件夹“attributes”中，因为它们非常有用。在advwrk中，它们是可见的，因此microsoft建议的结构也是可见的。再次感谢您的更新。我还将取消隐藏属性。用户没有使用Subselect-为什么要这样过度复杂查询？查询非常简单。但在实际操作中，报表中使用了数据过滤器等，并且使用subselect很容易实现。我们几乎总是使用subselect。在本例中，可以使用透视表中的“顶层”进行导航。
