How to design the table structure of the warehouse management system in MySQL to manage inventory supplier information?

In a warehouse management system, the management of inventory supplier information is a very important part. In MySQL, this information can be stored and managed by designing an appropriate table structure. This article will introduce how to design a table structure in MySQL to manage inventory supplier information and provide specific code examples.

When designing the table structure of the warehouse management system, you first need to consider the basic information of the inventory supplier, such as name, contact person, contact number, etc. We can create a table named "supplier" to store this information. The table structure example is as follows:

CREATE TABLE supplier (
id INT PRIMARY KEY AUTO_INCREMENT,
name VARCHAR(100) NOT NULL ,
contact_person VARCHAR(50) NOT NULL,
contact_phone VARCHAR(20) NOT NULL
);

In the above example, we created a table named "supplier", Contains four columns: id, name, contact_person and contact_phone. The id column is the primary key and is automatically incremented; the name column stores the supplier name; the contact_person column stores the contact name; the contact_phone column stores the contact number.

In addition to basic information, inventory suppliers also have other related information, such as the products supplied, supply prices, supply quantities, etc. In order to store this information, we can create a table named "supplier_product". The table structure example is as follows:

CREATE TABLE supplier_product (
id INT PRIMARY KEY AUTO_INCREMENT,
supplier_id INT NOT NULL,
product_name VARCHAR(100) NOT NULL,
price DECIMAL(10,2) NOT NULL,
quantity INT NOT NULL,
FOREIGN KEY (supplier_id) REFERENCES supplier (id)
);

In the above example, we created a table named "supplier_product", which contains five columns: id, supplier_id, product_name, price and quantity. The id column is the primary key and is automatically incremented; the supplier_id column is a foreign key, referencing the id column of the "supplier" table; the product_name column stores the product name; the price column stores the supply price; and the quantity column stores the supply quantity.

Through the above table structure design, we can easily store and manage inventory supplier information. The following are some specific operation examples:

1. Sample code for inserting supplier information:

INSERT INTO supplier (name, contact_person, contact_phone)
VALUES (' Supplier A', 'Zhang San', '1234567890');

2. Sample code to insert supplier product information:

INSERT INTO supplier_product (supplier_id, product_name, price, quantity)
VALUES (1, 'Product A', 10.99, 100);

3. Sample code to query product information of a supplier:

SELECT supplier.name, supplier_product.product_name, supplier_product.price, supplier_product.quantity
FROM supplier
INNER JOIN supplier_product
ON supplier.id = supplier_product.supplier_id
WHERE supplier.id = 1;

In the above example, we used INSERT and SELECT statements to demonstrate the operations of inserting supplier information and querying supplier product information. It can be modified and extended according to specific needs.

To sum up, through appropriate table structure design, inventory supplier information can be effectively managed in MySQL. When designing the table structure, you need to consider the basic information of the supplier and the product information related to it, and establish the association between the tables through foreign keys. In actual operation, you can use INSERT and SELECT statements to insert and query supplier information. We hope that the sample code provided in this article will be helpful in designing and managing the table structure of the warehouse management system.
