Question

我查看了有关此主题的几篇帖子，但未能看到解决此错误的问题。我已经链接了我想要包含在SQL 2008中的WHERE子句中的服务器。我能够成功执行查询而没有WHERE子句。我确信我忽略了一些需要一些建议的东西。多部分标识符的消息位于WHERE子句中的此行。

LAWNURSEDB.NGDemo.dbo.EXPORT_DIRECTTIME.SocialSecurityNumber

SELECT     dbo.VP_PUNCHORIGIN.PERSONNUM, EXPORT_DIRECTTIME_1.SocialSecurityNumber,         dbo.VP_PUNCHORIGIN.PERSONFULLNAME
FROM         dbo.VP_PUNCHORIGIN INNER JOIN
                  LAWNURSEDB.NGDemo.dbo.EXPORT_DIRECTTIME AS EXPORT_DIRECTTIME_1 ON 
                  dbo.VP_PUNCHORIGIN.PERSONNUM = EXPORT_DIRECTTIME_1.SocialSecurityNumber
WHERE     (dbo.VP_PUNCHORIGIN.PERSONNUM NOT IN
                      (SELECT     LAWNURSEDB.NGDemo.dbo.EXPORT_DIRECTTIME.SocialSecurityNumber AS Expr1
                        FROM          LAWNURSEDB.NGDemo.dbo.EXPORT_DIRECTTIME AS EXPORT_DIRECTTIME_1))

您在WHERE子句子查询中使用别名但不引用它：

SELECT p.PERSONNUM, 
    EXPORT_DIRECTTIME_1.SocialSecurityNumber,         
    p.PERSONFULLNAME
FROM dbo.VP_PUNCHORIGIN p
INNER JOIN LAWNURSEDB.NGDemo.dbo.EXPORT_DIRECTTIME AS EXPORT_DIRECTTIME_1 
    ON p.PERSONNUM = EXPORT_DIRECTTIME_1.SocialSecurityNumber
WHERE p.PERSONNUM 
         NOT IN (SELECT EXPORT_DIRECTTIME_2.SocialSecurityNumber 
                 FROM LAWNURSEDB.NGDemo.dbo.EXPORT_DIRECTTIME AS EXPORT_DIRECTTIME_2)
