如何在SSAS多维数据集中将null替换为0

Question

我需要在SSAS cube中将 null 替换为 0 。实现这个目标的正确方法是什么？

这是我目前的查询：

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来简化你的脚本。还将逻辑从子选择中移出到基本的WHERE子句中：

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] 
;

Answer 2

WITH MEMBER [Measures].[MEASURE_NONEMPTY] AS COALESCEEMPTY([Measures].[Service Period 
Count], 0)
SELECT {[Measures].[MEASURE_NONEMPTY]} 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] ) 

我使用上面的代码来解决问题。

Answer 3

我还没有测试，但如果有效，你可以尝试下面的方法，

SELECT {COALESCE (([Measures].[Employee Age Count]),"0") as AgeCount} 
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] )
