5. The products and categories tables


Well done! We'll now discuss the products and categories tables.

The products table stores information about products sold at the Northwind store. Each product has a unique product_id and a product_name. Each product is supplied by a single supplier (supplier_id) and belongs to a single category (category_id). Each product also has a certain unit_price. The discontinued column contains either a false (available in store) or a true (discontinued) that reflects the current availability of that product.

Products are organized into categories. The information about categories is stored in the categories table. Each category has a unique ID and a category_name. There is also a short description.

Because the products table contains the category_id column, you can join it with the categories table to get more information about the product's category (e.g., the category name).


For each product, display its name (product_name), the name of the category it belongs to (category_name), quantity per unit (quantity_per_unit), the unit price (unit_price), and the number of units in stock (units_in_stock). Order the results by unit price.
