使用Java实现数据库编程 项目（宠物商店）

创建数据库代码：

DROP DATABASE IF EXISTS petShop;
CREATE DATABASE petShop;  

USE petShop;
/*创建表*/
CREATE TABLE `petStore`(
    id INT AUTO_INCREMENT NOT NULL PRIMARY KEY,
    `name` CHAR() NULL,
    `password` CHAR() NULL,
    `balance` INT() NULL
 )ENGINE=INNODB DEFAULT CHARSET=utf8;  

 CREATE TABLE `petOwner`(
    id INT() AUTO_INCREMENT NOT NULL PRIMARY KEY,
    `name` CHAR() NULL,
    `password` CHAR() NULL,
    `money` INT() NULL
)ENGINE=INNODB DEFAULT CHARSET=utf8;  

CREATE TABLE `pet`(
    id INT() AUTO_INCREMENT NOT NULL PRIMARY KEY,
    `name` CHAR() NOT NULL,
    `typeName` CHAR() NULL,
    `health` INT() NULL,

    `birthday` TIMESTAMP NULL,
    `owner_id` INT() NULL,

CREATE TABLE `account`(

    `buyer_id` INT() NULL,
    `price` INT() NULL,
    `deal_time` TIMESTAMP NULL
)ENGINE=INNODB DEFAULT CHARSET=utf8;  

/*创建外键*/
ALTER TABLE `account`  ADD  CONSTRAINT fk_account_pet FOREIGN KEY(pet_id) REFERENCES `pet` (`id`);
ALTER TABLE `account`  ADD  CONSTRAINT fk_account_petOwner FOREIGN KEY(seller_id) REFERENCES `petOwner` (`id`);
