今天在MySQL中建表,一开始在MySQL Query Browser里建,可是总是报错,后来想想,这是只是一个方便操作的客户端软件,估计不行。

今天在MySQL中建表,一开始在MySQL Query Browser里建,可是总是报错,后来想想,这是只是一个方便操作的客户端软件,估计不行。后来又在服务器端管理软件MySQL Administrator下建表,可是还是出现同样的错误。没办法只好上网求助了。

一查原来才知道,在MySQL中建表大多数情况下是在DOS命令行下创建的。进入命令行后首先输入:net start MySQL (停止服务器用:net stop MySQL)服务器启动好后再输入:MySQL -uroot -p 这里的root代表用户名。按回车后将提示你输入密码:Enter password:密码就是安装的时候设置的密码。(在这一步可能出现MySQL不是内部命令的提示,那是因为环境变量没设置,应该把MySQL安装目录 下的bin目录添加到path中去,比如我的是D:\program files\MySQL\bin)当出项MySQL>的提示时就可以建表了。比如要在test中建立guestbook表,步骤如下: MySQL> use test Database changed MySQL>create table guestbook ->( ->serial_no int auto_increment not null primary key, ->name varchar(10) not null, ->guest_time varchar(10) not null ->); 这样一个表就创建成功了,不过在输入过程中要注意not null前要有个空格,还有就是逗号不要丢了,最后一行后没有逗号以及)后的";"号,这些都是数据库的基本知识,,可是我忘了,以至于建了好几次才成功。
