ODBC数据管理器 SqlServer实时数据同步到MySql

Posted 2020-11-04 笨小孩做开发

---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=‘[email protected]‘;--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

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 INT

                                SELECT@ID=ID,@QTY=QTY FROM INSERTED;

                                BEGIN

                                                EXEC loopback.db_ty2015.dbo.sp_insert@id,@qty;

                                END

CREATE PROCEDURE SP_INSERT

@ID INT,

@QTY INT

AS

BEGIN

                SET NOCOUNT ON

                                INSERT 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;

BEGIN

                EXEC loopback.db_ty2015.dbo.sp_update@id,@qty;

END

CREATE PROCEDURE SP_UPDATE

@QTY INT

AS

BEGIN

                SET NOCOUNT ON

                                UPDATE OPENQUERY(db_ty2015,‘select * from tb‘) SET qty=@qty WHERE id=@id

                SET NOCOUNT OFF

END

--delete

CREATE TRIGGER TR_DELETE_TB ON DB_TY2015.DBO.TB

FOR DELETE

AS

                DECLARE @ID INT

                SELECT@ID=ID FROM DELETED;

BEGIN

                EXEC loopback.db_ty2015.dbo.sp_DELETE@id;

END

CREATE PROCEDURE SP_DELETE

@ID INT

AS

BEGIN

                SET NOCOUNT ON

                                DELETE OPENQUERY(db_ty2015,‘select * from tb‘) WHERE id=@id

                SET 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‘)
