SQL错误(102):'>'附近的语法不正确

Question

我在这个CASE语句中遇到了一些真正的麻烦......它说我得到一个接近>的错误,它似乎指向第3行,其中检查> 15.但是我没有看到这个查询有什么问题.

我尝试在谷歌和这里搜索,并没有看到任何人有这个确切的问题,希望你可以指出它.

SELECT 
CASE 
    WHEN DATEDIFF(day, C1.RecvdDate, GETDATE()) > 15 AND DATEDIFF(day, C1.RecvdDate, GETDATE()) <= 30 THEN '15+'
    ELSE DATEDIFF(day, C1.RecvdDate, GETDATE()) > 30 AND DATEDIFF(day, C1.RecvdDate, GETDATE()) <= 60 THEN '30+'
    ELSE DATEDIFF(day, C1.RecvdDate, GETDATE()) > 60 AND DATEDIFF(day, C1.RecvdDate, GETDATE()) <= 90 THEN '60+'
    ELSE DATEDIFF(day, C1.RecvdDate, GETDATE()) > 90 AND DATEDIFF(day, C1.RecvdDate, GETDATE()) <= 120 THEN '90+'
    ELSE '120+'
END AS 'Days', 
C1.CallID AS 'Ticket#', A1.WhoAcknow AS 'Acknowledged By', C1.RecvdDate AS 'Received On', C1.Category, COUNT(*) As Assignments 

FROM [HEAT].[heat].[CallLog] C1 
LEFT JOIN [HEAT].[heat].[Asgnmnt] A1 ON C1.CallID = A1.CallID 
WHERE DATEDIFF(day, C1.RecvdDate, GETDATE()) > 15 AND C1.CallStatus = 'Open' AND C1.Category <> 'welfare' AND C1.CustType <> 'IFS' AND 
A1.Resolution = '' AND (A1.GroupName = 'Help Desk' AND A1.Assignee = 'EITS PIV Badge') 
GROUP BY C1.CallID, A1.WhoAcknow, C1.RecvdDate, C1.Category 
ORDER BY C1.RecvdDate ASC

提前致谢!

你的问题在于CASE表达.使用多个条件时,请使用WHEN而不是ELSE.ELSE应该只使用一次.

SELECT 
CASE 
    WHEN DATEDIFF(day, C1.RecvdDate, GETDATE()) > 15 AND DATEDIFF(day, C1.RecvdDate, GETDATE()) <= 30 THEN '15+'
    WHEN DATEDIFF(day, C1.RecvdDate, GETDATE()) > 30 AND DATEDIFF(day, C1.RecvdDate, GETDATE()) <= 60 THEN '30+'
    WHEN DATEDIFF(day, C1.RecvdDate, GETDATE()) > 60 AND DATEDIFF(day, C1.RecvdDate, GETDATE()) <= 90 THEN '60+'
    WHEN DATEDIFF(day, C1.RecvdDate, GETDATE()) > 90 AND DATEDIFF(day, C1.RecvdDate, GETDATE()) <= 120 THEN '90+'
    ELSE '120+'
END AS 'Days'...
