Oracle 存储过程基础知识
商业规则和业务逻辑可以通过程序存储在  中，这个程序就是存储过程。
存储过程是  !'(!) !'语句的组合，它使你能将执行商业规则的代码从你的应用
程序中移动到数据库。这样的结果就是，代码存储一次但是能够被多个程序使用。
要创建一个过程对象（*+），必须有 ,-./0.(-,."1-.系统权限。如
果这个过程对象需要被其他的用户 23使用，那么你必须有,-./0./45(-,."1-.权
限。执行*的时候，可能需要 6 权限。或者 .7,10./45(-,."1-.权限。
如果单独赋予权限，如下例所示： 
86$5%(-,."1-.9
