存储过程(Stored Procedure)是一组为了完成特定功能的SQL语句集,经编译后存储在数据库中,用户通过指定存储过程的名字并给定参数(如果该存储过程带有参数)来调用执行它。外部程序可以直接调用数据库里面定义好的存储过程,另外数据库内部的触发器(trigger)、或者其他存储过程也可以调用它。 存储过程的优点 (1)执行速度快:...

过程(procedure)又叫存储过程(stored procedure),是一个有名称的PL/SQL程序块 。 过程相当于java中的方法, 它注重的是实现某种业务功能 。 函数(function)也相当于java中的方法,它 注重计算并且总是有返回结果 。 过程和函数都是能够永久存储在数据库中的程序代码块,应用时通过调用执行 。
