SqlServer实时数据同步到MySql

---安装安装mysqlconnector

http://www.mysql.com/products/connector/

/*

配置mysqlconnector

ODBC数据管理器->系统DSN->添加->mysql ODBC 5.3 ANSI driver->填入data source name如jt,mysql的ip、用户名、密码即可

*/

--新建链接服务器

exec  sp_addlinkedserver

@server = 'MySqll_Aggregation' , --ODBC里面data source name

@srvproduct = 'MySql' , --自己随便

@provider = 'MSDASQL' , --固定这个

@datasrc =NULL,

@location =NULL,

@provstr = 'DRIVER={MySQL ODBC 5.3 ANSI Driver};SERVER=172.17.29.33;DATABASE=bi;UID=zhaowenzhong;PORT=3306;' ,

@catalog = NULL

---创建连接mysql数据库的账号及密码

exec  sp_addlinkedsrvlogin

@rmtsrvname = ' MySqll_Aggregation ' , ---- ODBC里面data source name

@useself = 'false' ,

@rmtuser = 'zhaowenzhong' , ---mysql账号

@rmtpassword = 'mysqldba@2015' ; --mysql账号其密码

---测试是否可以访问mysql数据库中的表

select  *  from  openquery ( MySqll_Aggregation , 'SELECT * FROM tb; ' )

-----建立允许远程访问连接操作

USE  [master]

GO

EXE C master . dbo . sp_serveroption @server = N'MySqll_Aggregation' , @optname = N'rpc out' , @optvalue = N'TRUE'

GO

EXEC  master . dbo . sp_serveroption @server = N'MySqll_Aggregation' , @optname = N'remote proc transaction promotion' , @optvalue = N'false'

GO

  

--建立LOOPBACK 服务器链接

EXEC  sp_addlinkedserver @server = N'loopback' , @srvproduct = N' ' , @provider = N'SQLNCLI' ,

@datasrc = @@SERVERNAME

go

--设置服务器链接选项，阻止SQL Server 由于远过程调用而将本地事务提升为分布事务（重点）

USE  [master]

GO

EXEC  master . dbo . sp_serveroption @server = N'loopback' , @optname = N'rpc out' , @optvalue = N'TRUE'

GO

EXEC  master . dbo . sp_serveroption @server = N'loopback' , @optname = N'remote proc transaction promotion' , @optvalue = N'false'

GO

---编写触发器和存储过程

--insert

AS

                                 @QTY  INT

---update

END

-------初始化数据      表已存在的情况

insert  into   penquery ( MySqll_Aggregation , 'select * from bi.tb' )   select * from [FSLogin] . [dbo] . [tb] with ( nolock )

---从mysql同步表结构及数据到sqlserver上

select  *  into   [SqlServerDBName] . dbo . MYTest   from    openquery ( localmysql , 'select * from mysqldbname.weibosession' )
