So let's wrap up the views. And then we'll talk about strings just for now. There's another view that gets the total each user spent in this one.
So I say, give me everything from that view. We can see everything in there. Now you can find anything in here.
People who spend over a certain amount—you can do any sort of filtering, right? You can just do a WHERE clause. You can say, WHERE total_spend is over a certain amount, or WHERE email LIKE '%@gmail.com'.
Just like we did before, you can apply any filters you want. You’re just treating it like a regular table.
