MySQL implements the delivery management function of the ordering system

MySQL is a relational database management system that is widely used to develop various types of applications. In the catering industry, ordering systems are a very common application. This article will focus on how to use MySQL to implement the delivery management function of the ordering system and provide specific code examples.

1. Database design
Before designing the database, it is first necessary to clarify the requirements and functions of the system. The delivery management function of the ordering system includes the following aspects:

1. Delivery staff management: record the basic information of the delivery staff, including name, mobile phone number, etc.
2. Order management: Record the basic information of the order, including order number, order time, user information, etc.
3. Delivery management: Record delivery details, including delivery personnel, orders, delivery time, etc.

Based on the above requirements, we can design the following database table structure:

1. Deliveryman table (deliveryman)

   • id : Deliveryman number
   • name: Name
   • phone: Mobile phone number

2. Order form (order_info)

   • id: Order number
   • order_time: Order time
   • user_info: User information

3. Delivery list(delivery)

   • id: Delivery number
   • deliveryman_id: Delivery man number
   • order_id: Order number
   • delivery_time: Delivery time

2. Database operation
Next we will use MySQL operation statements to implement the delivery management function of the ordering system. Assume that we have already created the database and corresponding table structure.

1. Add delivery information

   INSERT INTO deliveryman (name, phone) VALUES ('张三', '1234567890');

2. Add order information

   INSERT INTO order_info (order_time, user_info) VALUES ('2021-01-01 10:00:00', '张三 1234567890');

3. Add delivery information

   INSERT INTO delivery (deliveryman_id, order_id, delivery_time) VALUES (1, 1, '2021-01-01 10:30:00');

4. Query the delivery record of a certain delivery person

   SELECT delivery.id, order_info.order_time, order_info.user_info, delivery.delivery_time
   FROM delivery
   JOIN deliveryman ON delivery.deliveryman_id = deliveryman.id
   JOIN order_info ON delivery.order_id = order_info.id
   WHERE deliveryman.name = '张三';

5. Query the delivery status of an order

   SELECT delivery.id, deliveryman.name, deliveryman.phone, delivery.delivery_time
   FROM delivery
   JOIN deliveryman ON delivery.deliveryman_id = deliveryman.id
   WHERE delivery.order_id = 1;

6. Update delivery information

   UPDATE delivery SET deliveryman_id = 2 WHERE id = 1;

7. Delete delivery information

   DELETE FROM delivery WHERE id = 1;

The above is a sample code that uses MySQL to implement the delivery management function of the ordering system. Depending on actual needs, you can extend and optimize based on the above examples. At the same time, in order to improve system performance and security, you can also use indexes, transactions and other features to further optimize database operations.

Summary
This article introduces how to use MySQL to implement the delivery management function of the ordering system, and provides relevant code examples. The design and operation of the database are an important part of developing the ordering system. Reasonable database design and efficient database operation can improve the performance and stability of the system. I hope this article was helpful and I wish you success in your development!
