It has two parameters: orderStatus: IN parameter that is the order status which you want to count the orders. total: OUT parameter that stores the number of orders for a specific order status. The following is
参数(parameters) 分隔符(DELIMITER) MySQL通过delimiter来区分不同的SQL语句(SQL Statement),默认的分隔符是;; 对于procedure,会有多条SQL Statement,且MySQL的每个statement都需要以分隔符结束; 如果我们想把一个procedure作为一条statement,那么我们就不能用默认的分隔符;,否则MySQL Server就不会把procedure里面的多条...

存储过程(Stored Procedure)是一种在数据库中存储复杂程序,以便外部程序调用的一种数据库对象。目的是为了完成特定功能的SQL语句集,经编译创建并保存在数据库中,用户可通过指定存储过程的名字并给定参数(需要时)来调用执行。说白了就是数据库 SQL语言层面的代码封装与重用。创建的存储过程通常保存在数据库的数据字典中...
