从其他服务器的表里导数据的有关问题

从其他服务器的表里导数据的问题。
insert into dbo.td_Accept_Errata
( 
SDate, EntRegNO, EntName, RemoveDept, Reason, 
OperateMan, RecordID, EntID, cCodeBar, RemoveMan, RemovePhone, SMan, SMode, SReason, SState, 
OperateDate, PassMan, IsValid, IsDW
)
select top 10 
Sdtate, EntRegID, EntName, DeptCode=(select code from codedb..tcdept a where removedeptcode=a.deptname), Reason, 
PassMan,replace(newid(),'-',''),myentid,'','$admin$','','','1','历史数据导入：同意勘误','5',
Sdtate,'$admin$','1','0'
from dbo.Sheet2$ 

两个表导数据。Sheet2$ 里的myentid 如果有的话应该怎么从服务器A的库B的表mytable的里entid获得？
查询的条件是td_Accept_Errata.recordid=mytable.recordid


SQL语句应该怎么写，谢谢。

跨服务器导数据的问题，网上找的方法没解决。这个问题困扰我好几天了。
