如何解決此錯誤：「聯接表達式中的錯誤。無法解析查詢文本」

Question

我有一個複雜的SQL語句，當我加入這個'select'語句時出現錯誤。他們提示我這個錯誤： Error in Join expression. Can't parse query text.

我粘貼了這個SQL語句，我認爲會導致此錯誤。任何人都可以告訴我哪裏出了問題？我從來沒有把整個SQL語句粘貼到這裏，因爲我認爲如果你需要的話，這會很麻煩，請告訴我。有任何想法嗎？？？

Answer 1

你ON條款是括號) m ON b.UFISID = a.UFISEmpGroup外，試試這個，

SELECT a.EmpName, 
     CONCAT(b.StartTime, ' - ', b.EndTime) AS ShiftTime, 
     CONCAT(a.EmpTime, ' - ', ADDTIME(a.EmpTime, '0 1:0:0.000000')) AS BreakTime, 
     a.Break, 
     a.EmployeeOnBreak, 
     '' AS SignIn, 
     '' AS SignOut 
FROM satsschema.employeeslot a JOIN satsschema.ufis b m 
     ON b.UFISID = a.UFISEmpGroup
