不正确的语法错误在单词ON附近

我一直得到一个不正确的语法靠近单词ON，这段代码来自于上一篇文章的建议更改，我试图找到错误的位置，至今我没有运气弄清楚我缺少什么标点符号。代码是不正确的语法错误在单词ON附近

'WHERE ROWNUM = 1）ON AC.TMS_ID = CD.EMPLOYEE_ID;'看起来像子查询的别名闭幕后失踪' ）'。这对于我来说过于密集，以至于在没有分析的情况下直观地找出应该是哪个别名（'AC'或'CD'），但是您可能正在寻找'WHERE RowNum = 1）AS CD ON AC.TMS_ID = CD.EMPLOYEE_ID; ' –

我试过并仍然出现错误 – user2119980

学习CTE（公用表表达式）。如果你这样做不会是一个问题。 –

有一些不妥此查询（好吧，没有什么新的..）。最终的子查询中没有别名，但似乎还有更多。

简化和适当的缩进形式可能会帮助您察觉问题：

SELECT x 
FROM dbo.AC_Source AS AC 
INNER JOIN (
    SELECT x 
    FROM (
     SELECT x, ROW_NUMBER() OVER (PARTITION BY EmployeeID ORDER BY Meeting_End_Date DESC) As RowNum 
     FROM (
      SELECT x 
      FROM dbo.AC_CDData_1 
      UNION ALL 
      SELECT x 
      FROM dbo.TMS_Data_Latest_Career_Meeting_Rating 
      WHERE Plan_Year = '2013' 
     ) AS InnerSelect 
    ) AS CD ON AC.TMS_ID = CD.Employee_ID 
    WHERE RowNum = 1 
) ON AC.TMS_ID = CD.EMPLOYEE_ID;

首先，所有子查询都需要一个别名。所以，给子查询一个名字。我认为它是这样的：

SELECT AC.REG_NR, AC.DIS_NR, AC.GEMSID, AC.TMS_ID, AC.EMP_NA, AC.EMP_SEX_TYP_CD, 
     AC.EMP_EOC_GRP_TYP_CD, AC.DIV_NR, AC.CTR_NR, 
     AC.JOB_CLS_CD_DSC_TE, AC.JOB_GRP_CD, AC.Job_Function, AC.Job_Group, 
     AC.Meeting_Readiness_Rating, AC.Manager_Readiness_Rating, CD.Employee_ID, 
     CD.Meeting_Readiness_Rating AS Expr1, CD.Manager_Readiness_Rating AS Expr2, 
     CD.Meeting_End_Date, CD.EmployeeFeedback, 
     CD.DevelopmentForEmployee1, CD.DevelopmentForEmployee2, CD.DevelopmentForEmployee3, 
     CD.DevelopmentForEmployee4, CD.DevelopmentForEmployee5, 
     CD.Justification, CD.Changed, CD.Notes 
FROM dbo.AC_Source AS AC INNER JOIN 
     (SELECT EmployeeID AS Employee_ID, MeetingReadinessLevel AS Meeting_Readiness_Rating, ManagerReadinessLevel AS Manager_Readiness_Rating, 
           logdate AS Meeting_End_Date, EmployeeFeedback, DevelopmentForEmployee1, DevelopmentForEmployee2, DevelopmentForEmployee3, 
           DevelopmentForEmployee4, DevelopmentForEmployee5, Justification, Changed, Notes 
FROM (SELECT EmployeeID AS Employee_ID, MeetingReadinessLevel AS Meeting_Readiness_Rating, 
      ManagerReadinessLevel AS Manager_Readiness_Rating, 
      logdate AS Meeting_End_Date, EmployeeFeedback, DevelopmentForEmployee1, 
      DevelopmentForEmployee2, DevelopmentForEmployee3, 
      DevelopmentForEmployee4, DevelopmentForEmployee5, Justification, Changed, 
      Notes, 
      ROW_NUMBER() OVER (PARTITION BY EmployeeID ORDER BY Meeting_End_Date DESC) As RowNum 
     FROM (SELECT EmployeeID AS Employee_ID, MeetingReadinessLevel AS Meeting_Readiness_Rating, ManagerReadinessLevel AS Manager_Readiness_Rating,

THAT也不起作用，它给我所有领域的错误 – user2119980

这就是你的查询应该如何看起来像。如果你使用CTE，它很容易阅读，而且容易发现错误。在CTE http://technet.microsoft.com/en-us/library/ms190766(v=sql.105).aspx
