需要用到的数据库SQL：
代码如下：

drop database if exists db_ajax;

create database db_ajax;

use db_ajax;

create table user_table
(
user_id int auto_increment primary key,
name varchar(255) unique,
pass varchar(255)
);

create table photo_table
(
photo_id int auto_increment primary key,
title varchar(255),
fileName varchar(255),
owner_id int,
foreign key(owner_id) references user_table(user_id)
);
