我正在通过以下方式编写我的联接查询

    UPDATE  UPLOAD_TEMP
    SET     UPLOAD_TEMP.Borr_Add_Req = t2.YesNoResponse,
    FROM    UPLOAD_TEMP t1
    INNER JOIN GB_RequiredFields t2 ON t1.State = t2.StateCode
                                      AND t1.County_Id = t2.CountyId
                                      AND t1.Group_code = t2.Doc_type_group_code

但是也可以这样写

    UPDATE  UPLOAD_TEMP
    SET     UPLOAD_TEMP.Borr_Add_Req = t2.YesNoResponse,
    FROM    UPLOAD_TEMP t1
    INNER JOIN GB_RequiredFields t2 ON t1.State = t2.StateCode
    WHERE  t1.County_Id = t2.CountyId
       AND t1.Group_code = t2.Doc_type_group_code

两者之间是否有任何区别，这是首选的编码方式。
