6.2 创建数据库表create table 表名称（列声明）

创建一个students表，表中存放学号（id）名字（name）性别（sex）年龄（age）电话（tel）

通过文本编辑器保存为createtable.sql文件，通过命令提示符下的文件重定向执行该脚本，

6.3 将students表保存到feng数据库

F:\mysql-5.6.24-win32\bin>mysql -D feng -u root -p < C:\Users\Administrator\Desk

top\createtable.sql

Enter password: ******

F:\mysql-5.6.24-win32\bin>

id 列的名称

int （-8388608～8388607）

int unsigned (16777125)

not null 说明该列的值不能为空

auto_increment 在整数列中使用，插入数据时若该列为null，MySQL为自动生成一个比现存值更大的唯一标识符值。

primary key 表明该列是表的主键

char(8) 字符长度为8

tinyint 取值范围为（-127～128）

6.4 查询表信息，show tables; describe students;

mysql> show tables;
