两个数据库服务器复制数据:
--创建链接服务器 exec sp_addlinkedserver ‘ITSV‘ , ‘‘ , ‘SQLOLEDB‘ , ‘192.168.1.10‘ exec sp_addlinkedsrvlogin ‘ITSV‘ , ‘false‘ , null , ‘sa‘ , ‘sa@1234‘
--执行存储过程
exec batch_import ‘001‘
--单独处理"zsb_rvinfo"表
delete from zsb_rvinfo
insert into zsb_rvinfo select * from ITSV.DBName.dbo.zsb_rvinfo
--以后不再使用时删除链接服务器
exec sp_dropserver ‘ITSV‘, ‘droplogins‘
--跨服务器复制单表数据
insert into zsb_rvinfo select TOP (20000) * from openrowset(‘sqloledb‘,‘192.168.1.10‘;‘sa‘;‘sa@1234‘,‘select * from ..zsb_rvinfo‘)
