SQL Server中具有多個where條件的相同選擇條件

Question

當表中需要相同的字段但where條件不同時，是否可以執行類似的操作？

我已經嘗試過這樣做，但是其中缺少一些東西，這就是為什么它無法正常工作的原因。

;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'

我想得到的結果是“ PSC_Score_0_11”和其他的總和，其中district ='ABC'和district ='DEF'並將它們全部合並到一個表中。

我收到此查詢錯誤：

關鍵字“ AS”附近的語法不正確。

我想獲得每個地區的類似結果。

我猜您想要：

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似乎並不特別有用。
