用于获取非空值记录的MDX查询

Question

我是MDX的新手，你们中的任何人都可以帮我解决下面的问题吗？

1）从上面的结果集中，如何消除column1＆amp;中具有空值的行。 column3使用以下查询。

WITH
MEMBER TotalPatientCnt as '[Measures].[HealthPlanPatientCnt]'
MEMBER PrevalencePercent as '([Measures].[PatientCnt]*1.00/[Measures].    [TotalPatientCnt])*100'

SELECT 
NON EMPTY {[DimCP_Population].[Dr Key].[Dr Key]}
ON rows, 
 { 
     [Measures].[PatientCnt] ,[Measures].[TotalPatientCnt]
     ,[Measures].[PrevalencePercent]

}
ON columns
FROM [StrategyCompanionDWCube]
WHERE 
(
    [DimAnchorDate].[Date Key].&[20121231], 
    [DimCP_PCP].[PCP Key].&[124],
    [DimProduct].[Product Key].&[15],
    [DimHealthPlan].[Health Plan Key].&[1]
)

2）我有3个维度＆amp;分别采取3项措施

[DimCP_PCP], [DimProduct], [DimHealthPlan]

pcpCnt, productCnt, HelahtPlanPatientCnt

我想基于具有参数值的维度类型构建相同的TotalPatientCnt成员，希望需要编写case语句但我无法编写case语句请帮助我们以下示例。

WITH MEMBER TotalPatientCnt as 
case 
when [DimProduct].[Product Key].&[if getting anymember] then
'[Measures].[productCnt]'
when [DimHealthPlan].[Health Plan Key].&[if getting anymember] then
'[Measures].[HealthPlanPatientCnt]'
when [DimCP_PCP].[PCP Key].&[if getting anymember] then
'[Measures].[pcpCnt]'

如果我从[DimCP_PCP]获取任何参数，例如[DimCP_PCP].[PCP Key].&[124]需要显示TotalPatientCnt成员，如下所示

WITH MEMBER TotalPatientCnt as '[Measures].[pcpCnt]'

如果我从[DimHealthPlan]得到任何参数，例如[DimHealthPlan].[Health Plan Key].&[1]需要显示TotalPatientCnt成员，如下所示

WITH MEMBER TotalPatientCnt as '[Measures].[HealthPlanPatientCnt]'

如果我从[DimProduct]示例[DimProduct].[Product Key].&[15]获得任何参数需要显示TotalPatientCnt成员，如下所示

WITH MEMBER TotalPatientCnt as '[Measures].[productCnt]'

Answer 1

回答你的第一个问题：

由于NON EMPTY对此处的行不起作用，因为要排除的记录的第二列不为空，您可以使用很少记录的HAVING子句，如下所示：

...
{[DimCP_Population].[Dr Key].[Dr Key]}
HAVING NOT IsEmpty([Measures].[PatientCnt])
   AND NOT IsEmpty([Measures].[PrevalencePercent])
ON rows
...

Answer 2

SELECT 
(
[DimAnchorDate].[Date Key].&[20121231], 
[DimCP_PCP].[PCP Key].&[124],
[DimProduct].[Product Key].&[15],
[DimHealthPlan].[Health Plan Key].&[1],
[Measures].[PatientCnt],
[Measures].[TotalPatientCnt]
,[Measures].[PrevalencePercent]
) On 0,
NON EMPTY {[DimCP_Population].[Dr Key].[Dr Key]}
ON 1       
FROM [StrategyCompanionDWCube]

Understand the difference between NON-EMPTY vs Nonempty()

在这里，您可能会得到答案并明确NULL和EMPTY的概念
