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='MySqll_Aggregation', ----ODBC里面data source name
@location=NULL,
--@provstr='DRIVER={MySQL ODBC 5.3 ANSI Driver};SERVER=172.17.29.33;DATABASE=bi;UID=zhaowenzhong;PORT=3306;', --和@datasrc属性二选一
@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 Cmaster.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 （回路）
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
CREATE TRIGGER TR_INSERT_TB ON  DB_TY2015.DBO.TB
FOR INSERT
AS
DECLARE@ID INT,@QTY INTSELECT@ID=ID,@QTY=QTY FROM INSERTED;BEGINEXEC loopback.db_ty2015.dbo.sp_insert@id,@qty;END
CREATE PROCEDURE SP_INSERT
@ID INT,
@QTY INT
AS
BEGINSET NOCOUNT ONINSERT OPENQUERY(db_ty2015,'select * from tb')(id,qty) values (@id,@qty);SET NOCOUNT OFF
END---update
CREATE TRIGGERT R_UPDATE_TB ON DB_TY2015.DBO.TB
FOR UPDATE
AS
DECLARE @ID INT,@QTY INT
SELECT@ID=ID,@QTY=QTY FROM INSERTED;
BEGINEXEC loopback.db_ty2015.dbo.sp_update@id,@qty;
ENDCREATE PROCEDURE SP_UPDATE
@ID INT,
@QTY INT
AS
BEGINSET NOCOUNT ONUPDATE OPENQUERY(db_ty2015,'select * from tb') SET qty=@qty WHERE id=@idSET NOCOUNT OFF
END--delete
CREATE TRIGGER TR_DELETE_TB ON DB_TY2015.DBO.TB
FOR DELETE
ASDECLARE @ID INTSELECT@ID=ID FROM DELETED;
BEGINEXEC loopback.db_ty2015.dbo.sp_DELETE@id;
ENDCREATE PROCEDURE SP_DELETE
@ID INT
AS
BEGINSET NOCOUNT ONDELETE OPENQUERY(db_ty2015,'select * from tb') WHERE id=@idSET NOCOUNT OFF
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')
