SQL 不同ip的两个数据库数据插入，

简单示例:
//创建linkServer
exec sp_addlinkedserver 'srv_lnk','','SQLOLEDB','服务器名' 
//登陆linkServer
exec sp_addlinkedsrvlogin 'srv_lnk','false',null,'用户名','密码' 
//查询linkServer的数据库DataBaseA的表TableA
Select * From srv_lnk.DataBaseA.dbo.TableA
//List the tables in the linked server
EXEC sp_tables_ex txtsrv

下面是执行通过的代码，

--先执行这里
EXEC sp_addlinkedserver 'XHLink','','SQLOLEDB','10.0.0.27'
EXEC sp_addlinkedsrvlogin 'XHLink','false',null,'sa','******'
--再执行这里,不能一起执行
insert into xh
SELECT * FROM XHLink.marketing.dbo.xh
where xh_bm='0607' and xh_rq='2015/01/03'


insert into xhmx
SELECT * FROM XHLink.marketing.dbo.xhmx
where xhmx_dh in
(
SELECT xh_dh FROM XHLink.marketing.dbo.xh
where xh_bm='0607' and xh_rq='2015/01/03'
)
