Challenge: Products are not categorized
(mellow music) - [Presenter] You ready for a challenge? Again, one of the best ways to understand joins is to actually have samples that you work through. So in our database we have products and these products don't all have subcategories. So our goal with this challenge is to create a list of products that do not have the subcategory. Okay, you'll use your sample database that we've been working with. Once you understand joins this challenge won't take you about a minute or two but if you have to spend a little time here, that's okay. You can check out the next video to see how I accomplish the same task.
