購物商城數據庫設計-商品表DDL（Mysql）

你們好,以前咱們設計了購物商城的商品表結構（原文連接），如今咱們來具體實現表的DDL。

新建一個數據庫，名字叫mall，基字符集：utf-8，：數據庫排序規則：utf-8_general_ci

對於商品模塊，統一使用goods_作前綴。

首先是兩個比較簡單的表：分類表和品牌表

• 分類表：

CREATE TABLE `goods_category` (
  `id` bigint(20) unsigned NOT NULL auto_increment,
  `category_name` varchar(50) NOT NULL COMMENT '分類名稱',
  `gmt_create` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `gmt_update` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='分類表';

• 品牌表：

CREATE TABLE `goods_brand` (
  `id` bigint(20) unsigned NOT NULL auto_increment,
  `brand_name` varchar(50) NOT NULL COMMENT '品牌名稱',
  `gmt_create` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `gmt_update` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='品牌表';

接下來是SPU表：

CREATE TABLE `goods_spu` (
  `id` bigint(20) unsigned NOT NULL auto_increment,
  `spu_no` varchar(50) NOT NULL COMMENT '商品編號，惟一',
  `goods_name` varchar(50) NOT NULL COMMENT '商品名稱',
  `low_price` decimal(9,2) NOT NULL COMMENT '最低售價',
  `category_id` bigint(20) NOT NULL COMMENT '分類id',
  `brand_id` bigint(20) NOT NULL COMMENT '品牌id',
  `gmt_create` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `gmt_update` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`),
  UNIQUE KEY `uk_spu_no` (`spu_no`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='spu表';

而後是SPU規格相關的表：

• 規格表：

CREATE TABLE `goods_spec` (
  `id` bigint(20) unsigned NOT NULL auto_increment,
  `spec_no` varchar(50) NOT NULL COMMENT '規格編號',
  `spec_name` varchar(50) NOT NULL COMMENT '規格名稱',
  `gmt_create` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `gmt_update` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='規格表';

• 規格值表：

CREATE TABLE `goods_spec_value` (
  `id` bigint(20) unsigned NOT NULL auto_increment,
  `spec_id` bigint(20) NOT NULL COMMENT '規格id',
  `spec_value` varchar(50) NOT NULL COMMENT '規格值',
  `gmt_create` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `gmt_update` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='規格值表';

• SPU規格表

CREATE TABLE `goods_spu_spec` (
  `id` bigint(20) unsigned NOT NULL auto_increment,
  `spu_id` bigint(20) NOT NULL COMMENT 'spu_id',
  `spec_id` bigint(20) NOT NULL COMMENT 'spec_id',
  `gmt_create` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `gmt_update` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='spu規格表';

接下來是SKU相關的表：

• SKU表：

CREATE TABLE `goods_sku` (
  `id` bigint(20) unsigned NOT NULL auto_increment,
  `sku_no` varchar(50) NOT NULL COMMENT 'sku編號,惟一',
  `sku_name` varchar(50) NOT NULL COMMENT 'sku名稱(冗餘spu_name)',
  `price` decimal(9,2) NOT NULL COMMENT '售價',
  `stock` int(11) NOT NULL COMMENT '庫存',
  `shop_id` bigint(20) NOT NULL COMMENT '商鋪id,爲0表示自營',
  `spu_id` bigint(20) NOT NULL COMMENT 'spu_id',
  `gmt_create` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `gmt_update` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='sku表';

• 商鋪表：

CREATE TABLE `shop_info` (
  `id` bigint(20) unsigned NOT NULL auto_increment,
  `shop_name` varchar(50) NOT NULL COMMENT '店鋪名稱',
  `gmt_create` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `gmt_update` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='店鋪表';

• 增值保障表：

CREATE TABLE `goods_safeguard` (
  `id` bigint(20) unsigned NOT NULL auto_increment,
  `safeguard_name` varchar(50) NOT NULL COMMENT '保障名稱',
  `price` decimal(9,2) NOT NULL COMMENT '保障價格',
  `gmt_create` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `gmt_update` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='增值保障';

• SKU增值保障

CREATE TABLE `goods_sku_safeguard` (
  `id` bigint(20) unsigned NOT NULL auto_increment,
  `sku_id` bigint(20) NOT NULL COMMENT 'sku_id',
  `safeguard_id` bigint(20) NOT NULL COMMENT 'safeguard_id',
  `gmt_create` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `gmt_update` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='sku增值保障';

• SKU規格值表

CREATE TABLE `goods_sku_spec_value` (
  `id` bigint(20) unsigned NOT NULL auto_increment,
  `spu_id` bigint(20) NOT NULL COMMENT 'sku_id',
  `spec_value_id` bigint(20) NOT NULL COMMENT '規格值id',
  `gmt_create` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `gmt_update` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='sku規格值';
