Question

我遇到此错误

'PRINTING_DATE'在选择列表中无效，因为它不包含在聚合函数或GROUP BY子句中

但是通过使用OVER PARTITION BY，我希望此问题不会出现，为什么我仍然出现此错误？

DECLARE @REPORT AS NVARCHAR(50) = '2019-06-19 00:00:00.000'

SELECT 
    SUM(CASE 
           WHEN (P_DATE < @REPORT AND P_DATE > DATEADD(DAY, -7, @REPORT)) 
              THEN QTY_PICKED 
              ELSE 0 
        END) OVER (PARTITION BY PLANT, PARTS, P_DATE) AS SHIPPED,
    SUM(CASE 
           WHEN E_DATE > @REPORT AND E_DATE < DATEADD(DAY, 7, @REPORT) 
              THEN QTY_MII 
              ELSE 0 
        END) - SUM(CASE 
                      WHEN E_DATE > @REPORT AND E_DATE < DATEADD(DAY, 7, @REPORT) 
                         THEN QTY_PICKED 
                         ELSE 0 
                   END) AS TO_SHIP
FROM
    TABLE1 T1
INNER JOIN
    TABLE2 T2 ON T1.DELIVERY = T2.DELIVERY
WHERE 
    PLANT = 'XXX'

正如HoneyBadger指出的那样，第一个SUM中只有一个“ OVER PARTITION BY”，而第二个SUM中则没有。

尝试以下简化版本：

DECLARE @T1 TABLE(PLANT INT,PARTS INT,P_DATE DATE,QTY1 INT, QTY2 INT)
INSERT INTO @T1 VALUES(1,1,'2019-07-03',40,60)
INSERT INTO @T1 VALUES(1,1,'2019-07-03',50,80)

SELECT 
     SUM(QTY1) OVER (PARTITION BY PLANT, PARTS, P_DATE) AS SHIPPED
    ,SUM(QTY1) OVER (PARTITION BY PLANT, PARTS, P_DATE) - 
      SUM(QTY2) OVER (PARTITION BY PLANT, PARTS, P_DATE) AS TOSHIP
    ,SUM(QTY1)  -  SUM(QTY2) AS TOSHIP2
FROM  @T1
WHERE PLANT = 1

这将引发错误：在选择列表中，列“ @ T1.PLANT”无效，因为该列未包含在聚合函数或GROUP BY子句中。如果您注释/删除该行

,SUM(QTY1)  -  SUM(QTY2) AS TOSHIP2

它将产生结果。顺便说一句：在此示例中，错误也指向第一个SUM，但这不是问题。

目前还不清楚您要做什么。但我可以提供一个提示：如果您的结果集是返回一行的聚合，则窗口函数没有用。

因此，您可能需要这样做：

SELECT SUM(CASE WHEN (P_DATE < @REPORT AND P_DATE > DATEADD(DAY, -7, @REPORT)) 
                THEN QTY_PICKED 
                ELSE 0 
           END) AS SHIPPED,
          (SUM(CASE WHEN E_DATE > @REPORT AND E_DATE < DATEADD(DAY, 7, @REPORT) 
                   THEN QTY_MII 
                   ELSE 0 
               END) -
           SUM(CASE WHEN E_DATE > @REPORT AND E_DATE < DATEADD(DAY, 7, @REPORT) 
                    THEN QTY_PICKED 
                    ELSE 0 
               END)
          ) AS TO_SHIP
FROM TABLE1 T1 INNER JOIN
     TABLE2 T2
     ON T1.DELIVERY = T2.DELIVERY
WHERE PLANT = 'XXX';

当然，您可能希望返回不止一行的聚合查询：

SELECT PLANT, PARTS, P_DATE,
       SUM(CASE WHEN (P_DATE < @REPORT AND P_DATE > DATEADD(DAY, -7, @REPORT)) 
                THEN QTY_PICKED 
                ELSE 0 
           END) AS SHIPPED,
          (SUM(CASE WHEN E_DATE > @REPORT AND E_DATE < DATEADD(DAY, 7, @REPORT) 
                   THEN QTY_MII 
                   ELSE 0 
               END) -
           SUM(CASE WHEN E_DATE > @REPORT AND E_DATE < DATEADD(DAY, 7, @REPORT) 
                    THEN QTY_PICKED 
                    ELSE 0 
               END)
          ) AS TO_SHIP
FROM TABLE1 T1 INNER JOIN
     TABLE2 T2
     ON T1.DELIVERY = T2.DELIVERY
WHERE PLANT = 'XXX'
GROUP BY PLANT, PARTS, P_DATE;

甚至使用OVER PARTITION BY的汇总，分组错误
