🗣 Wd提问: price comparison tool mysql

🤖 Ai回答:
A price comparison tool using MySQL can be built by creating a database to store product information, including the product name, price, and the store where it is sold、The tool can then query the database to compare prices for a specific product across different stores.
Here is an example of how the database schema might look like:

CREATE TABLE products (
id INT PRIMARY KEY,
name VARCHAR(255),
price DECIMAL(10,2),
store VARCHAR(255)
);

To compare prices for a specific product, you can use a SQL query like this:

SELECT store, price FROM products WHERE name = 'Product Name';

This will return a list of stores and their prices for the specified product.
You can also add more features to the tool, such as sorting the results by price, adding filters for specific stores, and displaying the results in a user-friendly way.
It's worth noting that this is just a basic example and a real-world price comparison tool would likely require more complex database schema and queries, as well as additional features such as user authentication, caching, and more.
