用mysql设计一个商城管理系统，至少有十个表，给出具体代码

好的，以下是一个简单的商城管理系统的表结构设计的 MySQL 代码：

-- 用户表
CREATE TABLE `user` (
  `user_id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(20) NOT NULL,
  `password` varchar(32) NOT NULL,
  `email` varchar(50) NOT NULL,
  `phone` varchar(20) NOT NULL,
  PRIMARY KEY (`user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 商品表
CREATE TABLE `product` (
  `product_id` int(11) NOT NULL AUTO_INCREMENT,
  `product_name` varchar(50) NOT NULL,
  `product_description` varchar(255) NOT NULL,
  `product_price` decimal(10,2) NOT NULL,
  `product_stock` int(11) NOT NULL,
  PRIMARY KEY (`product_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 订单表
CREATE TABLE `order` (
  `order_id` int(11) NOT NULL AUTO_INCREMENT,
  `user_id` int(11) NOT NULL,
  `order_status` tinyint(4) NOT NULL,
  `order_total_amount` decimal(10,2) NOT NULL,
  `order_time` datetime NOT NULL,
  PRIMARY KEY (`order_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 订单详情表
CREATE TABLE `order_detail` (
  `order_detail_id` int(11) NOT NULL AUTO_INCREMENT,
  `order_id` int(11) NOT NULL,
  `product_id` int(11) NOT NULL,
  `buy_amount` int(11) NOT NULL,
  `product_price` decimal(10,2) NOT NULL,
  PRIMARY KEY (`order_detail_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 收货地址表
CREATE TABLE `address` (
  `address_id` int(11) NOT NULL AUTO_INCREMENT,
  `user_id` int(11) NOT NULL,
  `consignee_name` varchar(20) NOT NULL,
  `consignee_phone` varchar(20) NOT NULL,
  `address_detail` varchar(255) NOT NULL,
  PRIMARY KEY (`address_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 购物车表
CREATE TABLE `cart` (
  `cart_id` int(11) NOT NULL AUTO_INCREMENT,
  `user_id` int(11) NOT NULL,
  `product_id` int(11) NOT NULL,
  `buy_amount` int(11) NOT NULL,
  PRIMARY KEY (`cart_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 商品分类表
CREATE TABLE `category` (
  `category_id` int(11) NOT NULL AUTO_INCREMENT,
  `category_name` varchar(20) NOT NULL,
  `parent_category_id` int(11) NOT NULL,
  PRIMARY KEY (`category_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 商品评价表
CREATE TABLE `comment` (
  `comment_id` int(11) NOT NULL AUTO_INCREMENT,
  `user_id` int(11) NOT NULL,
  `product_id` int(11) NOT NULL,
  `comment_content` varchar(255) NOT NULL,
  `comment_time` datetime NOT NULL,
  PRIMARY KEY (`comment_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 物流表
CREATE TABLE `logistics` (
  `logistics_id` int(11) NOT NULL AUTO_INCREMENT,
  `order_id` int(11) NOT NULL,
  `logistics_status` tinyint(4) NOT NULL,
  `consignee_name` varchar(20) NOT NULL,
  `consignee_phone` varchar(20) NOT NULL,
  `address_detail` varchar(255) NOT NULL,
  PRIMARY KEY (`logistics_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 品牌表
CREATE TABLE `brand` (
  `brand_id` int(11) NOT NULL AUTO_INCREMENT,
  `brand_name` varchar(20) NOT NULL,
  `brand_description` varchar(255) NOT NULL,
  `brand_logo` varchar(255) NOT NULL,
  PRIMARY KEY (`brand_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

以上是用 MySQL 设计一个简单的商城管理系统的表结构，每个表都有其独特的字段，可以根据实际需求进行修改和优化。
