1.创创建数据库

create database python_test_1 charset=utf8;

2.使用数据库

 use python_test_1;

3.创建数据表students,classes

mysql> create table students(

    -> id int unsigned primary key auto_increment not null,

    -> name varchar(20) default '',

    -> age tinyint unsigned default 0,

    -> height decimal(5,2),

    -> gender enum('男','女','中性','保密') default '保密',

    -> cls_id int unsigned default 0,

    -> is_delete bit default 0);

查创建的表是否成功

查看表结构
3.1创建classes表

mysql> create table classes(

    -> id int unsigned auto_increment primary key not null,

    -> name varchar(30) not null);

4.向Students表中插入数据

mysql> insert into students

    -> values

    -> (0,'小明',18,180.00,2,1,0),

    -> (0,'小月月',18,180.00,2,1,1),

    -> (0,'彭于晏',29,185.00,1,1,0),

    -> (0,'刘德华',59,185.00,1,1,0),

    -> (0,'黄蓉',38,160.00,2,1,0),

    -> (0,'凤姐','28',150.00,4,2,1),

    -> (0,'王祖贤',18,172.00,2,1,1),

    -> (0,'周杰伦',36,NULL,1,1,0),

    -> (0,'程坤',27,181.00,1,2,0),

    -> (0,'刘亦菲',25,166.00,2,2,0),

    -> (0,'金星',33,162.00,3,3,1),

    -> (0,'静香',12,180.00,2,4,0),

    -> (0,'郭靖',12,170.00,1,4,0),

    -> (0,'周杰',34,176.00,2,5,0);

4.2向classes表中插入数据

mysql> insert into classes

    -> values

    -> (0,'python_01期'),

    -> (0,'python_02期');
