SQL Server数据实时同步至Oracle数据库中

1、使用SSMS中的链接服务器链接Oracle

请参考链接  SQLServer 客户端链接服务器到Oracle数据库 全攻略_sqlserver连接oracle数据库_简单的你我1314的博客-CSDN博客

2、使用触发器（insert update delete）获取更改的数据然后同步至Oracle中（使用openquery查询）

//openquery语句 ORCL是链接服务器的名称 
INSERT openquery (ORCL,'SELECT "id","name","age" FROM system."person"') values(3,'本司',30)//
delete openquery  (ORCL,'SELECT "id","name","age" FROM system."person" where "id"=1')
