I’ve been using SQL wrong this whole time

I've just never not used it to its full potential. Most people have used SQL at some point - but also just stick to the basics. When we need to do something complex, we instead do it in another programming language and send multiple queries. Even though it's very simple to solve in SQL. In this video I show 3 basic building blocks that will really supercharge your SQL usage - and make you an expert. Not only that, with this you will be able to run extremally powerful and scalable data processing without building all the infrastructure yourself.
