Extremely helpful and look forward to watching all the videos in the series. Just a tip for anyone who is new to T-SQL (Microsoft) or SQL in general. I would personally practice the JOINS he talks about. And even come back, and watch the video a couple times to really help it stick. Again amazing video thank you!
