MYSQL实时触发SQL SERVER 实例

以下给出如何实现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。

CREATE TABLE `accountsbackup` (
  `id` char(36) NOT NULL,
  `name` varchar(150) DEFAULT NULL,
  `date_entered` datetime DEFAULT NULL,
  `date_modified` datetime DEFAULT NULL,

  `ExecutingState` varchar(45) DEFAULT NULL,
  `ModificationTime` varchar(45) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

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。

SET ANSI_PADDING OFF

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。
