If you want to be a DBA for a living, Get Certified! Or at least try to, so you sound intelligent in interviews..
I will help you with the key takeaways from the Microsoft Training Kits for SQL Server. Starting with this one: Querying 2012, why this one you ask, it’s so old isn’t it? Actually this exam covers 2012 & 2014 and it is a great foundation for the fundamentals. Many production environments still run 2008 which is 10 years old at the time of this blog, and reports are there is slow adoption for the latest SQL 2016.
If you don’t know this stuff, it’s best to go get the book and study all the details, but I can give you the hi-lights to help you understand the ‘why’.

So here goes – the important takeaways, I learned so much by doing this exact thing, Reading Chapter by Chapter, cover to cover, even after 15 years of experience, I still had polishing to be done, and learning to do. Find my next blog in this series I will cover all Chapters from this Training Kit with Key Take-aways! Word of warning – this is not meant to be a substitute for buying the kit and doing yourself, I’m simply pointing out the things I find interesting after so many years in-the-trenches..
