Question

如果今天的日期介于FROMDATE和EXPIRYDATE之间，我试图求和多个折扣值（在客户导出的CSV中）。

如果我将折扣值加起来，一切都很好，但是如果我要检查今天是否在FROMDATE和EXPIRYDATE之间，它会迫使我将“ FROMDATE and EXPIRYDATE”添加到GROUP BY，这会导致重复的行和SUM不起作用。

这是代码，我用**签名有问题的部分

非常感谢您的帮助！

SELECT
CUSTOMERS.CUSTNAME AS 'ERP Code',
CUSTOMERS.CUSTDES AS 'Name',
CUSTOMERS.PHONE AS 'Phone',
(SELECT TOP 1 PHONEBOOK.CELLPHONE FROM PHONEBOOK WHERE 
CUSTOMERS.CUST=PHONEBOOK.CUST) AS 'Mobile',

不确定，但是CTE可能会在这里有所帮助，请尝试以下方法：

WITH CTE AS 
(
    SELECT CUSTOMERS.CUSTNAME AS 'ERP Code',
           CUSTOMERS.CUSTDES AS 'Name',
           CUSTOMERS.PHONE AS 'Phone',
           (SELECT TOP 1 PHONEBOOK.CELLPHONE FROM PHONEBOOK WHERE 
           CUSTOMERS.CUST=PHONEBOOK.CUST) AS 'Mobile',
           (SELECT TOP 1 PHONEBOOK.NAME FROM PHONEBOOK WHERE 
           CUSTOMERS.CUST=PHONEBOOK.CUST) AS 'Prop1 Contact Name',
           CUSTOMERS.FAX AS 'Fax',
           CUSTOMERS.ADDRESS AS 'Address',
           CUSTOMERS.STATE AS 'City',
           CUSTOMERS.ZIP AS 'ZIP Code',
           CUSTOMERS.VATNUM + CUSTOMERS.WTAXNUM  AS 'Goverment ID',
           CUSTOMERSA.EMAIL AS 'Email',
           **(SELECT SUM (DISCOUNTS.T$PERCENT) WHERE GETDATE() BETWEEN 
           zoom#system.dbo.tabula_dateconvert(DISCOUNTS.FROMDATE) AND 
           zoom#system.dbo.tabula_dateconvert(DISCOUNTS.EXPIRYDATE)) AS 'Discount',**
           ISNULL(CUSTPLIST.PLIST, -1) AS 'Price Level Code',
           (SELECT (PAY.PAYDES) FROM PAY WHERE CUSTOMERS.PAY=PAY.PAY) AS 'Prop2'

           FROM CUSTOMERS
           LEFT OUTER JOIN CUSTOMERSA
           ON CUSTOMERS.CUST=CUSTOMERSA.CUST
           LEFT OUTER JOIN CUSTDISCOUNT
           ON CUSTOMERS.CUST=CUSTDISCOUNT.CUST
           LEFT OUTER JOIN DISCOUNTS
           ON CUSTDISCOUNT.DISCOUNT=DISCOUNTS.DISCOUNT
           LEFT OUTER JOIN CUSTPLIST
           ON CUSTOMERS.CUST=CUSTPLIST.CUST
           LEFT OUTER JOIN  CUSTSTATS
           ON CUSTOMERS.CUSTSTAT=CUSTSTATS.CUSTSTAT

         GROUP BY CUSTOMERS.CUSTNAME, CUSTOMERS.CUSTDES, CUSTOMERS.PHONE, 
                  CUSTOMERS.CUST, CUSTOMERS.FAX, CUSTOMERS.ADDRESS, CUSTOMERS.STATE, 
                  CUSTOMERS.ZIP, CUSTOMERS.VATNUM, CUSTOMERS.WTAXNUM, 
                  CUSTOMERSA.EMAIL, CUSTPLIST.PLIST, CUSTOMERS.PAY
)

SELECT * FROM CTE WHERE CUSTOMERS.CUST > 0
and CUSTOMERS.CUSTSTAT between -4 and -2

SQL“ GROUP BY”忽略一行的多行
