I’ve had the good fortune to start working with LinkedIn Learning (which was formerly known as Lynda, but through acquisition became part of LinkedIn and now Microsoft), and I’ve recorded several SQL Server oriented courses there. You can find my author page here — these topics are oriented around a wide array of topics–security, concurrency, performance, and development.
In addition to the videos, you can follow along with the code samples I’m using in my demos. The format of the courses are videos that are around 5 minutes, so it’s easy to get up to view a few courses. If you have any questions around any of my training, hit me up here.
