1.安装安装mysqlconnector2.配置mysqlconnectorODBC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3.新建链接服务器exec sp_addlinkedserver@server='jt', --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=192.168.5.188;DATABASE=suzhou;UID=root;PORT=3306;',@catalog = NULLexec sp_addlinkedsrvlogin@rmtsrvname='jt',@useself='false',@rmtuser='root',@rmtpassword='password';select * from openquery(jt,'SELECT * FROM sz ; ')GOUSE [master]GOEXEC master.dbo.sp_serveroption @server=N'jt', @optname=N'rpc out', @optvalue=N'TRUE'GOEXEC master.dbo.sp_serveroption @server=N'jt', @optname=N'remote proc transaction promotion', @optvalue=N'false'GO---4.sqlserver和mysql新建库和表create database suzhou;create table sz(id int not null identity(1,1) primary key,orderno char
(20) not null,ordertime datetime not null default getdate(),remark varchar(200))gocreate table sz(id int
(11) not null ,orderno char
(20) not null,ordertime datetime
(6) not null ,remark varchar(200),primary key (id)) engine=innodb default charset=utf8;---5.建立回环--建立LOOPBACK 服务器链接EXEC sp_addlinkedserver @server = N'loopback' , @srvproduct = N' ' , @provider = N'SQLNCLI',@datasrc = @@SERVERNAMEgo--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]GOEXEC master.dbo.sp_serveroption @server=N'loopback', @optname=N'rpc out', @optvalue=N'TRUE'GOEXEC master.dbo.sp_serveroption @server=N'loopback', @optname=N'remote proc transaction promotion', @optvalue=N'false'GO----6.编写触发器和存储过程----6.1 insert--重写触发器use suzhougoalter trigger tr_insert_sz on suzhou.dbo.szfor insertasdeclare @id int, @orderno char
