Establish the delivery area table of the grocery shopping system in MySQL

To establish the delivery area table of the grocery shopping system in MySQL, specific code examples are required

In the grocery shopping system, the delivery area is an important piece of information, which determines Which areas can enjoy grocery shopping and delivery services. In order to facilitate management and query, we can create a delivery area table in the MySQL database.

First of all, we need to determine some basic fields for the delivery area table, such as area name, province, city, district, detailed address, etc. Next, we can use MySQL statements to create a delivery area table. The example is as follows:

CREATE TABLE delivery_area (
    id INT PRIMARY KEY AUTO_INCREMENT,
    area_name VARCHAR(50) NOT NULL,
    province VARCHAR(50) NOT NULL,
    city VARCHAR(50) NOT NULL,
    district VARCHAR(50) NOT NULL,
    address VARCHAR(100) NOT NULL
);

The above code creates a table named delivery_area, which contains id, area name, province, and city. , area, detailed address and other fields. Among them, the id field is the primary key and is used to uniquely identify each delivery area.

Next, we can insert some sample data into the delivery area table to simulate the real situation. An example is as follows:

INSERT INTO delivery_area (area_name, province, city, district, address)
VALUES ('东城区', '北京市', '北京市', '东城区', 'xxx街道xxx号'),
       ('西城区', '北京市', '北京市', '西城区', 'xxx街道xxx号'),
       ('朝阳区', '北京市', '北京市', '朝阳区', 'xxx街道xxx号'),
       ('海淀区', '北京市', '北京市', '海淀区', 'xxx街道xxx号');

The above code inserts 4 sample data into the delivery area table, representing different delivery areas in Beijing.

In actual use, we can query, insert, update and delete the delivery area table as needed to manage and maintain the information of the delivery area.

For example, to query a specific delivery area information, you can use the following statement:

SELECT * FROM delivery_area WHERE area_name = '朝阳区';

The above code will return all records with the area name 'Chaoyang District' in the delivery area table.

In short, establishing the delivery area table of the grocery shopping system in MySQL can help us easily manage and query the information of the delivery area in the system. By creating tables and inserting sample data, you can facilitate the delivery service of the system and perform further operations based on actual needs.
