如何在SSAS多维数据集中用0替换null

我需要在我的

SSAS多维数据集中用0替换null。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：

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] )

我还没有测试过，但如果可以的话，你可以试试下面的方法

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] )

我在解决方案中使用了上面的代码。
我认为
IIF（ISEMPTY…
非常标准

我还通过删除许多大括号简化了您的脚本，并将逻辑从subselect移到了basic
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] 
;

它返回的COALESCE函数在Microsoft Sql Server Analysis Services中不存在。我尝试使用COALESCEEMPTY（（[Measures].[Employee Age Count]），“0”，但在查询（1，9）中出错该函数要求1参数使用元组集表达式。使用了字符串或数值表达式。请让我检查它，因为我告诉过您当前无法测试它，但请让我再次检查它
