一般我们要根据数据库的纪录变化时，进行某种操作。我们习惯的操作方式是在程序中不停的查询表，判断是否有新纪录。这样耗费的资源就很高，如何提高这种效率，我想在表中创建触发器，在触发器中调用外部动态连接库通过消息或事件通知应用程序就可实现。而master的存储过程中最好能调用外部的动态连接库，我们在触发器中调用master的存储过程即可。本文提供了动态库与存储过程的具体实现

-we have to follow the general database records change, with some operators. We are accustomed to the mode of operation is kept of the proceedings of the inquiry table to determine whether there is any new records. Such resources spent on high, how to improve the efficiency of this, I think, in the table to create triggers, Calling the trigger external dynamic link library through news or event notification application procedures can be achieved. And master's stored procedure can be called the best external dynamic link library, We call master trigger the process can be stored. This paper provides a dynamic process and storage for a concrete realization
