ssas - 如何在SSAS立方体中用0替换null

Question

我需要在我的 SSAS 多维数据集中 中将 null 替换为 0。实现这一目标的正确方法是什么？

这是我当前的查询:

SELECT {([Measures].[Employee Age Count])} 
ON COLUMNS, { ([Dim Gender].[Gender Name].[Gender Name].ALLMEMBERS * 
[Dim Age Ranges].[Age Range ID].[Age Range ID].ALLMEMBERS ) }  ON ROWS 
FROM ( SELECT ( { [Dim Location].[Location].[Location Grp Name].&[BOSTON] }) ON COLUMNS
FROM [People Dashboard]) 
WHERE ( [Dim Location].[Location].[Location Grp Name].&[BOSTON] )

当前查询的结果:

Answer 1

我认为 IIF(ISEMPTY... 非常标准。

我还通过删除相当多的大括号并将逻辑从子选择移到基本的 WHERE 子句中来简化您的脚本:

WITH MEMBER [Measures].[MEASURE_NONEMPTY] AS 
  IIF(
     ISEMPTY([Measures].[Service Period Count])
     ,0
     ,[Measures].[Service Period Count]
  )
SELECT 
   {[Measures].[MEASURE_NONEMPTY]} ON 0,
       [Dim Gender].[Gender Name].[Gender Name].ALLMEMBERS 
     * [Dim Age Ranges].[Age Range ID].[Age Range ID].ALLMEMBERS  
     ON 1
FROM [People Dashboard]
WHERE [Dim Location].[Location].[Location Grp Name].&[BOSTON] 
;
