Save it for when you need it Resources mentioned 📑 Network Chuck - basic intro course, one of the best tech YouTubers, particularly for cyber security, and networking 📑 FreeCodeCamp - 4 hour SQL course by Mike Dane for complete beginners 📑 Luke Barousse - 5 hour SQL with a focus on Data analytics. Lots of practice, not just you watching a person do something, which is a route to tutorial hell 📑 Codecademy - have a good free intro SQL course, they have a big production team for their content so it’s usually really good. Then practice, practice, practice. You don’t learn it by watching someone. You get your hands dirty and solve problems you’ll have in the real world with databases and add on the complexity gradually. That’s it, not rocket science, don’t over think it. 👾 SQL Bolt 👾 SQL Zoo 👾 SQL Fiddle #sql #machinelearning #tech #programming #coding #computerscience #datascience #dataanalytics
