setmeal表为套餐表,用于存储套餐的信息。具体表结构如下:
字段名 | 数据类型 | 说明 | 备注 |
---|---|---|---|
id | bigint | 主键 | 自增 |
name | varchar(32) | 套餐名称 | 唯一 |
category_id | bigint | 分类id | 逻辑外键 |
price | decimal(10,2) | 套餐价格 | |
image | varchar(255) | 图片路径 | |
description | varchar(255) | 套餐描述 | |
status | int | 售卖状态 | 1起售 0停售 |
create_time | datetime | 创建时间 | |
update_time | datetime | 最后修改时间 | |
create_user | bigint | 创建人id | |
update_user | bigint | 最后修改人id |
setmeal_dish表为套餐菜品关系表,用于存储套餐和菜品的关联关系。具体表结构如下:
字段名 | 数据类型 | 说明 | 备注 |
---|---|---|---|
id | bigint | 主键 | 自增 |
setmeal_id | bigint | 套餐id | 逻辑外键 |
dish_id | bigint | 菜品id | 逻辑外键 |
name | varchar(32) | 菜品名称 | 冗余字段 |
price | decimal(10,2) | 菜品单价 | 冗余字段 |
copies | int | 菜品份数 |
