我一直在单词ON附近得到错误的语法，这段代码来自之前帖子的建议更改，我试图找出错误的位置，到目前为止，我没有运气搞清楚我是什么标点符号失踪。代码是

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,

首先，所有子查询都需要别名。因此，请为子查询指定名称。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, 
                               logdate AS Meeting_End_Date, EmployeeFeedback, DevelopmentForEmployee1, DevelopmentForEmployee2, DevelopmentForEmployee3, 
                               DevelopmentForEmployee4, DevelopmentForEmployee5, Justification, Changed, Notes
            FROM   dbo.AC_CDData_1
            UNION ALL
            SELECT Employee_ID, Meeting_Readiness_Rating, Manager_Readiness_Rating, Meeting_End_Date, '' AS EmployeeFeedback, '' AS DevelopmentForEmployee1, 
                               '' AS DevelopmentForEmployee2, '' AS DevelopmentForEmployee3, '' AS DevelopmentForEmployee4, '' AS DevelopmentForEmployee5, '' AS Justification, 
                               '' AS Changed, '' AS Notes
            FROM  dbo.TMS_Data_Latest_Career_Meeting_Rating
            WHERE (Plan_Year = '2013')) AS InnerSelect
          ) cd
     ) cd
     ON AC.TMS_ID = CD.EMPLOYEE_ID and rownum = 1

这是您的查询应该是这样的。如果您使用CTE，则易于阅读且容易发现错误。

这个查询有问题（好吧，没什么新东西......）。最终子查询中没有别名，但似乎还有更多。

简化且正确缩进的形式可以帮助您发现问题：

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;
