某些属性的 TOPCOUNT 查询结果不正确

Question

我试图找出哪一年的经销商销售额在每个州和省中最高。我正在使用 Adventure Works DW 2008 R2 数据库。

这是我得到的查询 -

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]

当谈到法国时，它显示 (null) 作为结果集。另外，为什么它不列出所有州省，而只列出 select 中的少数几个？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，我收到错误消息说地理层次结构已经存在。

Answer 1

要删除空值，您可以使用 BDESC 而不是 DESC。额外的 B 意味着所有自然等级顺序将被打破

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];

要添加国家/地区并避免您看到的错误，请使用未使用的属性层次结构 [Geography].[Country] 而不是 1 轴上已有的用户层次结构 [Geography].[Geography]：

SELECT 
  {[Reseller Sales Amount]} ON COLUMNS
 ,{
    Generate
    (
      [Geography].[Geography].[Country].MEMBERS
     ,TopCount
      (
        Order
        (
            [Geography].[Country].[Country]*
            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TOP-filters在关卡上的通用选项实现。

TOP-rules can be set for every level.

用于数据的详细分析（Expand、Drilldown）。

Aggregates are formed based on TOP.

设置排序顺序就可以了，只要数据在大多数枢轴 Table.
