如果您使用要在from子句中更新的表格并在其中添加别名（此处为m），那么您必须使用该别名您的UPDATE声明：UPDATE m SET ..... - 您无法在UPDATE声明顶部使用其他别名“重新定义”该表

试试这个：

Update m              // use the alias you've defined on the FROM line!
set m.territory_no = u.territory_no,  
    m.key_sales_force = u.key_sales_force,  
    ......
    m.fcl_zip = u.fcl_zip  
from 
    [dbo].[ManPlan_Prescriber_Roster] m   // use this alias in UPDATE 
join 
    (select 
         territory_no,  
         key_sales_force,  
         .....
         fcl_zip 
     from 
         [dbo].[RepRosterUpd$]  
     where 
         filedt = '2016-05-18') u on m.territory_no = u.territory_no 
                                  and m.key_sales_force = u.key_sales_force
                                  and m.territory_type_id = u.territory_type_id
