数据导入问题，等了一天，没有人解决，被挤出第一页了：（

if exists (select name='proc_ss' from sysobjects where name='proc_ss' and type='P')
drop procedure proc_ss
go

create procedure proc_ss
as
set ansi_warnings on

update b
set BH_ZHU=a.BH_ZHU, BH=a.BH, SSMC=a.SSMC, SSJC=a.SSJC, LB=a.LB, BL=a.BL, BZ=a.BZ, LRR=a.LRR, LRSJ=a.LRSJ, BS=a.BS, BGRQ=a.BGRQ

insert into opendatasource ('sqloledb', 'data source = IP2(本机); user ID = sa; password = sa').sms.dbo.cqgl_ss ([BH_ZHU], [BH], [SSMC], [SSJC], [LB], [BL], [BZ], [LRR], [LRSJ], [BS], [BGRQ])

where not exists(select 1 from es.dbo.cqgl_ss where a.BH_ZHU=BH_ZHU and a.BH=BH and a.SSJC=SSJC)
go
--==========================
exec proc_ss
执行存储过程时，提示对象名b无效。
单机的时候没有这个问题，是不是不同IP的情况下不能使用别名？要怎么解决呢？（两台电脑是同一个局域网内）
请指点初学者。
顺祝2008年身体健康，工作顺利
