Tsql SSAS数据源视图变量

我正在尝试使用新的命名查询在SSAS的数据源视图中添加一个表。脚本如下所示：

Declare @AvgInvestment float;
SELECT  @AvgInvestment=SUM(Investment)/COUNT(distinct meta_ID)
FROM AAAA



SELECT        Player, Investment, 
              InvestmentRange=
              Case When Investment >=0 AND  Investment <(@AvgInvestment/3)                       THEN 1
                   When Investment >=(@AvgInvestment/3) AND  Investment <(4*@AvgInvestment/3)    THEN 2                           
                   When Investment >=(4*@AvgInvestment/3) AND  Investment <(6*@AvgInvestment/3)  THEN 3                         
                   When Investment >=(2*@AvgInvestment)                                          THEN 4
             END                              
FROM  AAAA 

但是，SSAS不允许在DVS的SQL查询中声明变量。是否有任何可能的方法来修改SQL语句，使其没有变量？我试图从AAAA中将@AvgInvestment替换为SELECT SUMMINVENT/COUNTdistinct meta_ID，但它不起作用

感谢所有可能的解决方案

您可以使用变量与平均值相加。例如：

SELECT Player, Investment, 
       InvestmentRange=
       Case When Investment >=0 AND  Investment <(a.avg/3)              THEN 1
            When Investment >=(a.avg/3) AND  Investment <(4*a.avg/3)    THEN 2
            When Investment >=(4*a.avg/3) AND  Investment <(6*a.avg/3)  THEN 3                         
            When Investment >=(2*a.avg)                                 THEN 4
       END                               
FROM  AAAA cross join 
(select SUM(Investment)/COUNT(distinct meta_ID) as avg from aaaa) a

在数据源视图中可以完美地工作。存储过程在那里不起作用。

您可以使用变量与平均值合并。例如：

SELECT Player, Investment, 
       InvestmentRange=
       Case When Investment >=0 AND  Investment <(a.avg/3)              THEN 1
            When Investment >=(a.avg/3) AND  Investment <(4*a.avg/3)    THEN 2
            When Investment >=(4*a.avg/3) AND  Investment <(6*a.avg/3)  THEN 3                         
            When Investment >=(2*a.avg)                                 THEN 4
       END                               
FROM  AAAA cross join 
(select SUM(Investment)/COUNT(distinct meta_ID) as avg from aaaa) a

不记得是否可能在SSAS的数据源视图中，但您可以尝试使用存储过程获取数据。不记得是否可能在SSAS的数据源视图中，但您可以尝试使用存储过程获取数据。
