使用mysql中遇到的几个问题

mysql question

首先mysql不是可视化的,可以通过命令行进行操作,包括创建数据库、表、添加数据等等。那岂不是很不方便了吗?

不用担心啊,你担心之前绝对有人担心过了。哈哈,如果想像mssql中那样可视化操作,可以使用mysql administrator,这是在你做软件开发时,如果做网站开发,假如说使用php,那么你可以用可视化工具phpadmin。恩,好了,对mysql你应该有一个初始印象了吧~~
其次,mysql创建存储过程,呵呵,mysql这家伙搞特殊,创建存储过程参数不能带有“@”,而且在程序里面使用参数时要在参数前加“?”,恩,因为习惯了mssql,所以刚才开始使用mysql创建存储过程时头疼了一会呢。mysql里面不适用“@”,而用“?”代替。
再者,通过程序访问mysql创建的存储过程时时需要在存储过程前面加上数据库的名称的,而且还有一点就是数据库的名称必须小写,呵呵,这让我从一个迷阵出来又进了另一个迷阵。
下面继续:
mysql的存储过程不能有return,当然mysql的函数可以有。那如果存储过程有返回值怎么办?不用怕哦,mysql提供了参数修饰符in、out、inout。看字面你就知道意思了吧?呵呵,如果某个参数是用于输出结果的,可以用out进行修饰,程序里面使用就可以了。
还有好多,等你用时就遇到了,哈哈,祝你好运哦~~
