下面附上建表代码：
create table ftx(
id int not null auto_increment,
link varchar(100) not null,
adr varchar(100) not null,
adress varchar(100) not null,
price varchar(100) not null,
phone varchar(100) not null,
PRIMARY KEY (id )
);
alter table ftx modify column price varchar(100) character set utf8 not null #修改字段的字符集
值得注意的是：在插入数据的时候，记得要相关字段的字符集变成utf8，否则会报错，最好刚开始建表就指定该表的字符集为utf8
