Expert Level SQL Tutorial

In this video I will show you what it takes to be a SQL expert. I will cover unions, recursive/hierarchical queries and partitioning.

THANK YOU! Finally an "Expert Level" video that doesn't teach to a beginner. It's so hard to find actually advanced information amidst all the beginner's tutorials.

I have been writing SQL for a long time and it's so refreshing to learn something new AND useful for work! Thank you!

I took, and passed, my 70-761 a few months ago; however, your tutorial would have made studying a lot easier. Great Job!

Been using SQL as a functional ERP resource so I don’t know if I am an expert. This is very well done and IMHO not too far out of reach for someone who has the basics. Where have you been hiding?
