MYSQL实时触发SQL SERVER实现同步实例
我们对MYSQL数据表更新实时触发sql server里面对应表的增删改操作，首先，增加原来的mysql的表的触发器，包括以下三个：
插入数据：

上面必须增加behaviortype字段，因为如果是I代表插入，U代表更新，D代表删除，接着增加mysql的备份表，专门记录这三种操作。

这个表如无意外，ID不要设置成为唯一索引，因为本身就存在多条同一个记录的更改。接下来在sql server建立对应的表。

最后建立sql server存储过程，这边尤其要注意的是要rtrim mysql char类型，因为sql server对这个是完全填充的，如果有多余空格插入会报错，同时 要定义为 别名，因为在 下面的插入是根据别名字段来的。

最后再开启sql server代理，因为本身这个需要计划任务每秒去monitor这个mysql变化，因为sql server这边只能设置10秒更新一次，那这边就只能如此，如果要看是否成功，可以右击该计划任务查看历史记录。
sqlserver数据实时同步到mysql
1.安装安装mysqlconnector
2.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
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 = NULL
exec sp_addlinkedsrvlogin
@rmtsrvname='jt',
@useself='false',
@rmtuser='root',
@rmtpassword='password';
select * from openquery(jt,'SELECT * FROM sz ; ')
GO
USE [master]
GO
EXEC master.dbo.sp_serveroption @server=N'jt', @optname=N'rpc out', @optvalue=N'TRUE'
GO
EXEC 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)

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 = @@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'

----6.编写触发器和存储过程
----6.1 insert
