1.登录数据库并创建数据库db_ck
创建完成后使用到我们创建的数据库。
2.创建表t_hero
根据hero属性包括（id，name，nickname，age，gender，address，weapon，types）
创建完成后进行查看
使用命令desc t_hero进行查看表建立是否成功;
mysql> create database db_ck;
ERROR 1007 (HY000): Can't create database 'db_ck'; database exists
mysql> use db_ck;
Database changed
mysql> create table t_hero(
-> id int,
-> name varchar(100),
-> nickname varchar(100),
-> age int,
-> gender varchar(2),
-> address varchar(100),
-> weapon varchar(100),
-> types varchar(100));
Query OK, 0 rows affected (0.02 sec)
