一、登录数据库并创建数据库db_ck

二、创建表t_hero

表属性包括（id，name，nickname，age，gender，address，weapon，types）

sql 复制代码

mysql> create table t_hero(
    ->  id int,
    -> name varchar(100),
    -> age int,
    -> gender varchar(2),
    -> address varchar(100),
    -> weapon varchar(100),
    -> types varchar(100));
Query OK, 0 rows affected (0.06 sec)
 
mysql> desc t_hero;
+----------+--------------+------+-----+---------+-------+
| Field    | Type         | Null | Key | Default | Extra |
+----------+--------------+------+-----+---------+-------+
| id       | int          | YES  |     | NULL    |       |
| name     | varchar(100) | YES  |     | NULL    |       |
| age      | int          | YES  |     | NULL    |       |
| gender   | varchar(2)   | YES  |     | NULL    |       |

| types    | varchar(100) | YES  |     | NULL    |       |
+----------+--------------+------+-----+---------+-------+

三、插入我们的四大名著人物数据

mysql> insert into t_hero values(1,"孙悟空",800,"男","花果山","如意金箍棒","妖");
Query OK, 1 row affected (0.01 sec)
 
mysql> insert into t_hero values(2,"林黛玉",20,"女","贾府","无","人类");
