1、启用Ad Hoc Distributed Queries
在使用openrowset/opendatasource前搜先要启用Ad Hoc Distributed Queries服务,因为这个服务不安全所以SqlServer默认是关闭的
启用Ad Hoc Distributed Queries的方法
SQL Server 阻止了对组件 ‘Ad Hoc Distributed Queries‘ 的 STATEMENT‘OpenRowset/OpenDatasource‘
的访问,因为此组件已作为此服务器安全配置的一部分而被关闭。系统管理员可以通过使用
sp_configure 启用 ‘Ad Hoc Distributed Queries‘。有关启用 ‘Ad Hoc Distributed Queries‘ 的详细
信息,请参阅 SQL Server 联机丛书中的 "外围应用配置器"。
启用Ad Hoc Distributed
Queries的方法,执行下面的查询语句就可以了:
exec sp_configure ‘show advanced
options‘,1
reconfigure
exec sp_configure ‘Ad Hoc
Distributed
Queries‘,1
reconfigure
使用完毕后,记得一定要要关闭它,因为这是一个安全隐患,切记执行下面的SQL语句
exec sp_configure ‘Ad Hoc Distributed
Queries‘,0
reconfigure
exec sp_configure ‘show
advanced options‘,0
reconfigure
2、使用示例
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 本地表
3、自己写的例子
select * from openrowset(‘SQLOLEDB‘,‘Server=(local);PWD=***;UID=sa;‘,‘select * from TB.dbo.school‘) as t
select * from openrowset(‘SQLOLEDB‘,‘Server=(local);PWD=***;UID=sa;‘,TB.dbo.school) as t
select * from openrowset(‘SQLOLEDB‘,‘Server=(local);Trusted_Connection=yes;‘,TB.dbo.school) as t
select * from openrowset(‘SQLOLEDB‘,‘(local)‘;‘sa‘;‘***‘,‘select * from TB.dbo.school‘) as t
select * from openrowset(‘SQLOLEDB‘,‘(local)‘;‘sa‘;‘***‘,TB.dbo.school) as t
select * from openrowset(‘SQLOLEDB‘,‘(local)‘;‘sa‘;‘***‘,‘select school.id as id1,people.id as id2 from TB.dbo.school inner join TB.dbo.people on school.id=people.id‘) as t
--openrowset使用SQLNCLI的一些例子(SQLNCLI在SqlServer2005以上才能使用)
select * from openrowset(‘SQLNCLI‘,‘(local)‘;‘sa‘;‘***‘,‘select * from TB.dbo.school‘) as t
select * from openrowset(‘SQLNCLI‘,‘Server=(local);Trusted_Connection=yes;‘,‘select * from TB.dbo.school‘) as t
select * from openrowset(‘SQLNCLI‘,‘Server=(local);UID=sa;PWD=***;‘,‘select * from TB.dbo.school‘) as t
select * from openrowset(‘SQLNCLI‘,‘Server=(local);UID=sa;PWD=***;‘,TB.dbo.school) as t
select * from openrowset(‘SQLNCLI‘,‘Server=(local);UID=sa;PWD=***;DataBase=TB‘,‘select * from dbo.school‘) as t
--openrowset其他使用
insert openrowset(‘SQLNCLI‘,‘Server=(local);Trusted_Connection=yes;‘,‘select name from TB.dbo.school where id=1‘) values(‘ghjkl‘)/*要不要where都一样,插入一行*/
update openrowset(‘SQLNCLI‘,‘Server=(local);Trusted_Connection=yes;‘,‘select name from TB.dbo.school where id=1‘) set name=‘kkkkkk‘
delete from openrowset(‘SQLNCLI‘,‘Server=(local);Trusted_Connection=yes;‘,‘select name from TB.dbo.school where id=1‘)
--opendatasource使用SQLNCLI的一些例子
select * from opendatasource(‘SQLNCLI‘,‘Server=(local);UID=sa;PWD=***;‘).TB.dbo.school as t
select * from opendatasource(‘SQLNCLI‘,‘Server=(local);UID=sa;PWD=***;DataBase=TB‘).TB.dbo.school as t
--opendatasource使用OLEDB的例子
select * from opendatasource(‘SQLOLEDB‘,‘Server=(local);Trusted_Connection=yes;‘).TB.dbo.school as t
--opendatasource其他使用
insert opendatasource(‘SQLNCLI‘,‘Server=(local);Trusted_Connection=yes;‘).TB.dbo.school(name) values(‘ghjkl‘)/*要不要where都一样,插入一行*/
update opendatasource(‘SQLNCLI‘,‘Server=(local);Trusted_Connection=yes;‘).TB.dbo.school set name=‘kkkkkk‘
delete from opendatasource(‘SQLNCLI‘,‘Server=(local);Trusted_Connection=yes;‘).TB.dbo.school where id=1
--openquery使用OLEDB的一些例子
exec sp_addlinkedserver ‘ITSV‘, ‘‘, ‘SQLOLEDB‘,‘(local)‘
exec sp_addlinkedsrvlogin ‘ITSV‘, ‘false‘,null, ‘sa‘, ‘***‘
select * FROM openquery(ITSV, ‘SELECT * FROM TB.dbo.school ‘)
--openquery使用SQLNCLI的一些例子
exec sp_addlinkedserver ‘ITSVA‘, ‘‘, ‘SQLNCLI‘,‘(local)‘
exec sp_addlinkedsrvlogin ‘ITSVA‘, ‘false‘,null, ‘sa‘, ‘***‘
select * FROM openquery(ITSVA, ‘SELECT * FROM TB.dbo.school ‘)
--openquery其他使用
insert openquery(ITSVA,‘select name from TB.dbo.school where id=1‘) values(‘ghjkl‘)/*要不要where都一样,插入一行*/
update openquery(ITSVA,‘select name from TB.dbo.school where id=1‘) set name=‘kkkkkk‘
delete openquery(ITSVA,‘select name from TB.dbo.school where id=1‘)
