About SQL Crash Course

What is SQL Crash Course all about?

This course has a simple mission to help anyone looking to learn SQL, or brush up on their SQL skills.

It's completely free to use, but if you want to use any of the material or lessons elsewhere please drop me a note on the contact details below as a courtesy.

Even better, if you use the SQL lessons here to help you bag a data analyst job, or even a promotion at your current job, I'd love to hear about it and add it to our list of testimonials. These really help other folks overcome their fear of getting started learning SQL and are a great hep to the data community. The more the merrier I say!
