在sqlserver下增加MYSQL的链接服务器，实现分布式数据库开发第一步

首先要在SQLserver上服务器上这装ODBC对mysql的支持，我下载了mysql-connector-odbc-5.1.5-win32.rar，安装后在ODBC中有了DRIVER={MySQL ODBC 5.1 Driver}

 

第二步，按下面的SQL脚本来执行

-- 查询已有的链接服务器
exec sp_linkedservers;

-- 脚本方式
EXEC sp_addlinkedserver 
    @server='MySQLTest',
    @srvproduct = 'zerolone',
    @provider = 'MSDASQL',
    @datasrc = NULL,
    @location = null,
    @provstr = 'DRIVER={MySQL ODBC 5.1 Driver};SERVER=127.0.0.1;DATABASE=zerolone;UID=root;PORT=3306;',
    @catalog = NULL
go
    EXEC sp_addlinkedsrvlogin 
    @rmtsrvname='MySqlTest',
    @useself='false',
    @rmtuser='root',
    @rmtpassword='123456';
go

SELECT * FROM OPENQUERY (PCTMYSQL2 ,'select * from monolithpro_cate' )

INSERT OPENQUERY (PCTMYSQL2, 'SELECT id,parentid,level,title FROM monolithpro_cate')
VALUES ('','0','0','zhangzongqi');

UPDATE OPENQUERY (PCTMYSQL2, 'SELECT parentid,level,title FROM monolithpro_cate WHERE id = 320') 
SET parentid = '2',LEVEL=3, title=title+'pct';

DELETE OPENQUERY (PCTMYSQL2, 'SELECT id FROM monolithpro_cate WHERE id = 316');

最后，好了可以实现在SQLserver下，添删改MYSQL里的数据了。
