大家好,之前我们设计了购物商城的商品表结构(原文链接)，现在我们来具体实现表的DDL。

新建一个数据库，名字叫mall，基字符集：utf-8，：数据库排序规则：utf-8_general_ci

对于商品模块，统一使用goods_做前缀。

首先是两个比较简单的表：分类表和品牌表

分类表：

CREATE TABLE `goods_category` (

`id` bigint(20) unsigned NOT NULL auto_increment,

`category_name` varchar(50) NOT NULL COMMENT '分类名称',

`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='分类表';

品牌表：

CREATE TABLE `goods_brand` (

`id` bigint(20) unsigned NOT NULL auto_increment,

`brand_name` varchar(50) NOT NULL COMMENT '品牌名称',

`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';

接下来是SPU表：

CREATE TABLE `goods_spu` (

`id` bigint(20) unsigned NOT NULL auto_increment,

`spu_no` varchar(50) NOT NULL COMMENT '商品编号，唯一',

`goods_name` varchar(50) NOT NULL COMMENT '商品名称',

`low_price` decimal(9,2) NOT NULL COMMENT '最低售价',

`category_id` bigint(20) NOT NULL COMMENT '分类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';

然后是SPU规格相关的表：

规格表：

CREATE TABLE `goods_spec` (

`id` bigint(20) unsigned NOT NULL auto_increment,

`spec_no` varchar(50) NOT NULL COMMENT '规格编号',

`spec_name` varchar(50) NOT NULL COMMENT '规格名称',

`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='规格表';

规格值表：

CREATE TABLE `goods_spec_value` (

`id` bigint(20) unsigned NOT NULL auto_increment,

`spec_id` bigint(20) NOT NULL COMMENT '规格id',

`spec_value` varchar(50) NOT NULL COMMENT '规格值',

`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='规格值表';

SPU规格表

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规格表';

接下来是SKU相关的表：

SKU表：

CREATE TABLE `goods_sku` (

`id` bigint(20) unsigned NOT NULL auto_increment,

`sku_no` varchar(50) NOT NULL COMMENT 'sku编号,唯一',

`sku_name` varchar(50) NOT NULL COMMENT 'sku名称(冗余spu_name)',

`price` decimal(9,2) NOT NULL COMMENT '售价',

`stock` int(11) NOT NULL COMMENT '库存',

`shop_id` bigint(20) NOT NULL COMMENT '商铺id,为0表示自营',

`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';

商铺表：

CREATE TABLE `shop_info` (

`id` bigint(20) unsigned NOT NULL auto_increment,

`shop_name` varchar(50) NOT NULL COMMENT '店铺名称',

`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='店铺表';

增值保障表：

CREATE TABLE `goods_safeguard` (

`id` bigint(20) unsigned NOT NULL auto_increment,

`safeguard_name` varchar(50) NOT NULL COMMENT '保障名称',

`price` decimal(9,2) NOT NULL COMMENT '保障价格',

`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规格值表

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 '规格值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规格值';
