Question

我有一个场景，必须对结果集进行分区并指定频率。

例如，以下MDX查询：

WITH MEMBER [MEASURES].[PERC_1] AS
    AGGREGATE ( EXISTING  [DIM CUSTOMER].[CUSTOMER ID].[ALL].CHILDREN,[MEASURES].[AMOUNT])

SELECT
[MEASURES].[PERC_1] ON 0,
[DIM CUSTOMER].[CUSTOMER ID].CHILDREN,[DIM CUSTOMER].[NAME].CHILDREN        
FROM [ANALYSIS DW]
WHERE ([DIM CUSTOMER].[ADDRESS].[ALL])

应该返回此结果：

现在，我希望将此结果集划分为存储桶。如果我的桶大小为3，则桶应为

0-30
31-60
61-100

这些存储桶是根据上述perc_1指标的最大值和最小值计算得出的;即，0最小，100最大。铲斗计算为（0 + 100）/ 3 - （0-30,31-60,61-100）。

现在，上述结果集中频率分布后的结果应如下所示 -

         frequency
 0-30      4
 31-60     4 
 61-100    2

WITH SET [0-30 set] AS
         Filter([DIM CUSTOMER].[CUSTOMER ID].CHILDREN,
                [MEASURES].[PERC_1] >= 0 AND [MEASURES].[PERC_1] <= 30
               )
     SET [31-60 set] AS
         Filter([DIM CUSTOMER].[CUSTOMER ID].CHILDREN,
                [MEASURES].[PERC_1] >= 31 AND [MEASURES].[PERC_1] <= 60
               )
     SET [61-100 set] AS
         Filter([DIM CUSTOMER].[CUSTOMER ID].CHILDREN,
                [MEASURES].[PERC_1] >= 61 AND [MEASURES].[PERC_1] <= 100
               )
     MEMBER [DIM CUSTOMER].[CUSTOMER ID].[0-30] AS
            NULL
     MEMBER [DIM CUSTOMER].[CUSTOMER ID].[31-60] AS
            NULL
     MEMBER [DIM CUSTOMER].[CUSTOMER ID].[61-100] AS
            NULL
     MEMBER [Measures].[frequency] AS
            CASE [DIM CUSTOMER].[CUSTOMER ID].CurrentMember
                 WHEN [DIM CUSTOMER].[CUSTOMER ID].[0-30] THEN
                      [0-30 set].Count
                 WHEN [DIM CUSTOMER].[CUSTOMER ID].[31-60] THEN
                      [31-60 set].Count
                 WHEN [DIM CUSTOMER].[CUSTOMER ID].[61-100] THEN
                      [61-100 set].Count
            END
SELECT { [Measures].[frequency] } ON 0,
       { 
         [DIM CUSTOMER].[CUSTOMER ID].[0-30],
         [DIM CUSTOMER].[CUSTOMER ID].[31-60],
         [DIM CUSTOMER].[CUSTOMER ID].[61-100]
       } ON 1
  FROM [ANALYSIS DW]
WHERE ([DIM CUSTOMER].[ADDRESS].[ALL])

我认为你不能在MDX中完全做到这一点，因为“3”是MDX查询的参数，因为你至少需要在MDX语句中明确地拥有类似于桶的成员定义的东西。 WITH子句（或会话级CREATE语句）是您可以创建行轴上显示的成员的唯一位置，即使它们仅用作占位符且不包含任何逻辑。

您需要一个外部工具来生成如上所述的参数特定MDX语句。

MDX对结果集进行bucketizing并分配频率
