Exercise

Select the name of each product category and the revenue (name that column Revenue) that it generated. Sort the results by Revenue in descending order.

Show a product category even if there were no sales for a particular category. In this case, the revenue is null.

Stuck? Here's a hint!

You need to LEFT JOIN the following tables together:

  • Categories,
  • Products,
  • OrderItems.
