不同服务器数据库之间的数据操作

 

--创建链接服务器 

exec sp_addlinkedserver   'ITSV ', ' ', 'SQLOLEDB ', '远程服务器名或ip地址 ' 

exec sp_addlinkedsrvlogin  'ITSV ', 'false ',null, '用户名 ', '密码 ' 

 

--查询示例 

select * from ITSV.数据库名.dbo.表名 

 

--导入示例 

select * into 表 from ITSV.数据库名.dbo.表名 

 

--以后不再使用时删除链接服务器 

exec sp_dropserver  'ITSV ', 'droplogins ' 

 

--连接远程/局域网数据(openrowset/openquery/opendatasource) 

--1、openrowset 

 

--查询示例 

select * from openrowset( 'SQLOLEDB ', 'sql服务器名 '; '用户名 '; '密码 ',数据库名.dbo.表名) 

 

--生成本地表 

select * into 表 from openrowset( 'SQLOLEDB ', 'sql服务器名 '; '用户名 '; '密码 ',数据库名.dbo.表名) 

 

--把本地表导入远程表 

insert openrowset( 'SQLOLEDB ', 'sql服务器名 '; '用户名 '; '密码 ',数据库名.dbo.表名) 

select *from 本地表 

 

--更新本地表 

update b 

set b.列A=a.列A 

 from openrowset( 'SQLOLEDB ', 'sql服务器名 '; '用户名 '; '密码 ',数据库名.dbo.表名)as a inner join 本地表 b 

on a.column1=b.column1 

 

--openquery用法需要创建一个连接 

 

--首先创建一个连接创建链接服务器 

exec sp_addlinkedserver   'ITSV ', ' ', 'SQLOLEDB ', '远程服务器名或ip地址 ' 

--查询 

select * 

FROM openquery(ITSV,  'SELECT *  FROM 数据库.dbo.表名 ') 

--把本地表导入远程表 

insert openquery(ITSV,  'SELECT *  FROM 数据库.dbo.表名 ') 

select * from 本地表 

--更新本地表 

update b 

set b.列B=a.列B 

FROM openquery(ITSV,  'SELECT * FROM 数据库.dbo.表名 ') as a  

inner join 本地表 b on a.列A=b.列A 

 

--3、opendatasource/openrowset 

SELECT   * 

FROM   opendatasource( 'SQLOLEDB ',  'Data Source=ip/ServerName;User ID=登陆名;Password=密码 ' ).test.dbo.roy_ta 

--把本地表导入远程表 

insert opendatasource( 'SQLOLEDB ',  'Data Source=ip/ServerName;User ID=登陆名;Password=密码 ').数据库.dbo.表名 

select * from
