步骤一:创建数据库
步骤二:创建表
步骤三:插入数据
例题:
1、创建一个英雄表(hero),管于四大名著的
主键
name 英雄(人物)名字
nickname 昵称 (代号)
address 那本书(西游,水浒)
groups 组(此时我们可以看为妖、神、鬼,国家等等)
email 邮件(随意编排)
telphone 电话(电话号码)
解题思路及步骤:
第一步:创建数据库 db_hero
第二步:创建表,包括约束的制定。 t_hero
第三步:插入数据
实验步骤:
步骤一:创建数据库
mysql> create database db_hero;
Query OK, 1 row affected (0.01 sec)
mysql> use db_hero
Database changedmysql> show tables;
Empty set (0.00 sec)
步骤二:创建表
mysql> CREATE TABLE IF NOT EXISTS t_hreo (
-> id int primary key auto_increment, # 此处经行主键约束并设置为自增长的整数类型
-> name varchar(50) not null unique, # 非空约束以及唯一约束
-> nickname varchar(255) unique, #
-> address varchar(20) check(address in("水浒", "西游")), # 8.0特有的默认值约束
-> `groups`varchar(20) not null, # 非空约束
-> email varchar(20),
-> telphone int
-> );
Query OK, 0 rows affected (0.03 sec)
代码:
CREATE TABLE IF NOT EXISTS t_hreo ( id int primary key auto_increment, name varchar(50) not null unique, nickname varchar(255) unique, address varchar(20) check(address in("水浒", "西游")), `groups`varchar(20) not null, email varchar(20), telphone int );
# 自我检查:
groups 为关机键字不能为列名,因此需要反引号
primary key 在同一个表中只能使用一次。
检查:
mysql> show tables;
+-------------------+ | Tables_in_db_hero | +-------------------+ | t_hreo | +-------------------+ 1 row in set (0.00 sec)
mysql> desc t_hreo;
+----------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------+--------------+------+-----+---------+----------------+ | id | int | NO | PRI | NULL | auto_increment | | name | varchar(50) | NO | UNI | NULL | | | nickname | varchar(255) | YES | UNI | NULL | | | address | varchar(20) | YES | | NULL | | | groups | varchar(20) | NO | | NULL | | | email | varchar(20) | YES | | NULL | | | telphone | int | YES | | NULL | | +----------+--------------+------+-----+---------+----------------+ 7 rows in set (0.00 sec)
步骤三:插入数据
由于此处要填入数据较多我们选择先写模板,当模板添加成功时。我们在经行批量话编辑,最后在统一输入。
经行输入模板:
mysql> insert into t_hreo values(null, "孙悟空", "齐天大圣" , "西游", " 妖" , "123@qq.123", 0123456789);
Query OK, 1 row affected (0.00 sec)mysql> select * from t_hreo;
+----+-----------+--------------+---------+--------+------------+-----------+ | id | name | nickname | address | groups | email | telphone | +----+-----------+--------------+---------+--------+------------+-----------+ | 1 | 孙悟空 | 齐天大圣 | 西游 | 妖 | 123@qq.123 | 123456789 | +----+-----------+--------------+---------+--------+------------+-----------+ 1 row in set (0.00 sec)
输出结果符合预期效果,开始进行统一编辑。
开始进行统一编辑:
