在SQL Server中具有多个where条件的相同选择条件

Question

当表中需要相同的字段但具有不同的where条件时，是否可以执行类似的操作。

我试图这样做，但有一些缺失，这就是为什么它不能正常工作。

;WITH ProductsCTE (PSC_Score_0_11, PSC_Score_12_18, PSC_Score_19_23,
                   PSC_Score_24_34, PSC_Score_35_50, PSC_Score_51_100,
                   Total AS
( 
    SELECT
        SUM(CONVERT(int, PSC_Score_0_11)) AS PSC_Score_0_11,
        SUM(CONVERT(int, PSC_Score_12_18)) AS PSC_Score_12_18,
        SUM(CONVERT(int, PSC_Score_19_23)) AS PSC_Score_19_23,
        SUM(CONVERT(int, PSC_Score_24_34)) AS PSC_Score_24_34,
        SUM(CONVERT(int, PSC_Score_35_50)) AS PSC_Score_35_50,
        SUM(CONVERT(int, PSC_Score_51_100)) AS PSC_Score_51_100,
        (SUM(CONVERT(int, PSC_Score_0_11)) + SUM(CONVERT(int, PSC_Score_12_18)) + 
         SUM(CONVERT(int, PSC_Score_19_23)) + SUM(CONVERT(int, PSC_Score_24_34)) + 
         SUM(CONVERT(int, PSC_Score_35_50)) + SUM(CONVERT(int, PSC_Score_51_100))) AS Total
    FROM
        VillageLevelPscData
)
SELECT * 
FROM ProductsCTE
WHERE [DISTRICT_NAME] = 'ABC'

UNION ALL 

SELECT * 
FROM ProductsCTE
WHERE [DISTRICT_NAME] = 'DEF'

我希望将结果作为“PSC_Score_0_11”的总和以及其他地区='ABC'和地区='DEF'的结果，并将它们合并为一个表。

我收到此查询的错误：

关键字“AS”附近的语法不正确。

我想为每个区域得到这样的结果。

我猜你想要：

select district_name,
       sum(CONVERT(int,PSC_Score_0_11 )) as PSC_Score_0_11,
       sum(CONVERT(int,PSC_Score_12_18 )) as PSC_Score_12_18,
       sum(CONVERT(int,PSC_Score_19_23 )) as PSC_Score_19_23,
       sum(CONVERT(int,PSC_Score_24_34 )) as PSC_Score_24_34,
       sum(CONVERT(int,PSC_Score_35_50 )) as PSC_Score_35_50,
       sum(CONVERT(int,PSC_Score_51_100 )) as PSC_Score_51_100,
       (SUM(CONVERT(int,PSC_Score_0_11 )) + SUM(CONVERT(int,PSC_Score_12_18 )) + 
SUM(CONVERT(int,PSC_Score_19_23 )) + SUM(CONVERT(int,PSC_Score_24_34 ))
 + SUM(CONVERT(int,PSC_Score_35_50 ))+ SUM(CONVERT(int,PSC_Score_51_100 ))
       ) as Total
from VillageLevelPscData
group by district_name;

CTE似乎并不特别有用。
