【问题描述】：
我有一种情况，我正在寻找 MDX 指导。
环境：SQL Server 2008 R2,SSRS 2008 R2
维度：列 DimMainProvider :ProviderName DimA学年：学年 DimSectorSubjectArea:Estyn DimLearningAim:LearningAim参考
事实：列 Learning:MainProviderKey,AgeBandKey,LearningAimKey,SuccessFlag
我想要的是 1) 对于特定的 MainProvider，按成功率获取 Top 10 LearningAims 并在 tablix 中显示 2）对于 tablix 上的每一行，还显示箱线图，它基本上需要所有 Mainproviders 中特定 LearningAim 的 Min、Max、Quartile1、Quartile3 成功率
我有 2 个 MDX 查询
a) 获得主要提供者的前 10 项活动（简体） MDX 版本如下）
WITH
SET Top10LearningAimsForSuccessRate
AS
NonEmpty(
TOPCOUNT([ReportedLearningAims],10,[Measures].[SuccessRate]),
[Measures].[SuccessRate]
)
SELECT
{
[Measures].[SuccessRate]
} ON COLUMNS
,NON EMPTY
{
EXISTS(
Top10LearningAimsForSuccessRate
,,"Learnings")
} ON ROWS
FROM
(
SELECT {[Measures].[TerminatedAssessableLASum]
,[Measures].[SuccessfulLASum]} ON COLUMNS
,{(StrToSet("[DimMainProvider].[ProviderName].&[44]",CONSTRAINED))} On ROWS
FROM [FECube]
)
WHERE
( StrToSet("[DimAcademicYear].[AcademicYear].[AcademicYear].[2009/10]",CONSTRAINED),
StrToSet("[DimSectorSubjectArea].[Estyn].&[2]",CONSTRAINED)
)
b) 另一个接受 LearningAim 作为参数并执行的查询 统计计算并给我数值（简化版 MDX 下面）
WITH
SET ProviderwideLearningAims
AS
ORDER(
NonEmpty( [DimMainProvider].[ProviderName].[ProviderName],
[Measures].[SuccessRate]
)
,[Measures].[SuccessRate],BASC
)
MEMBER [Measures].[MaxValue]
AS
Max(ProviderwideLearningAims,[SuccessRate]),FORMAT_STRING = "Percent"
MEMBER [Measures].[MinValue]
AS
Min(ProviderwideLearningAims,[SuccessRate]),FORMAT_STRING = "Percent"
MEMBER [Measures].[MedianValue]
AS
Median(ProviderwideLearningAims,[SuccessRate]),FORMAT_STRING = "Percent"
Member [Measures].[ProviderCount] As [ProviderwideLearningAims].Count
MEMBER [Measures].[MeanValue]
AS
(SUM(ProviderwideLearningAims,[SuccessRate])/[Measures].[ProviderCount]),FORMAT_STRING = "Percent"
MEMBER [Measures].[LearningAimUniqueName]
AS
[DimLearningAim].[LearningAimReference].CurrentMember.UniqueName
Select
{ [Measures].[LearningAimUniqueName]
,[Measures].[MinValue]
,[Measures].[MaxValue]
,[Measures].[MedianValue]
,[Measures].[MeanValue]
} ON COLUMNS,
{
NonEmpty([DimLearningAim].[LearningAimReference].[LearningAimReference],ProviderwideLearningAims)
} ON ROWS
FROM
(
SELECT
StrToSet("[DimLearningAim].[LearningAimReference].&[50024991]",CONSTRAINED) ON COLUMNS
FROM [FECube]
)
WHERE
( StrToSet("[DimAcademicYear].[AcademicYear].[AcademicYear].[2009/10]",CONSTRAINED),
StrToSet("[DimSectorSubjectArea].[Estyn].&[2]",CONSTRAINED)
)
我最初的想法是为收到的每个学习目标触发第二个查询 从第一个查询开始，但我无法在 SSRS 数据集中实现这一点 模型。 所以现在我回到了 MDX 级别并希望以某种方式合并这些 两个。
