SQL and I are SELECT * crossed lovers, but there was a time that I knew no SQL at all, a dark time, a time where my tables were held in Excel and I could type into the cells and drag them on command. One day, I was shown the true beauty that is SQL. With it’s static outputs that you can’t type into or move and that just sit there doing nothing. It was love at first SELECT.
The first few weeks and months learn SQL, the knowledge came at me thick and fast. I was learning so much SQL, I thought I’d have it down in no time.
Then one day, I reached a hard limit. I just wasn’t improving as fast as before. Suddenly, I was not the SQL genius I thought. Things that were too hard, WAY too hard. I had reached the point of knowing I had plateaued, but not how to get off the plateau.
Then one day, a friend at work mentioned SQL Server Central to me, a website I had previously never heard of. A place full of online SQL nerds who knew seemingly infinite SQL. This was the start of my journey into the world of SQL blogs, videos, conferences and more places you can learn online.

A great place for basic SQL, I still come here to check on syntax I rarely use. Is it SELECT INTO or INSERT INTO?
YouTube
Just type in SQL for beginners and there will be tons of content for you out there.
If You’re Already Skilled But Want To Be Skillederer
There are so many people who kindly give away SQL information for free and sometimes even more information for money i.e. paid courses.
This list is not exhaustive, just people I know of.
SQL People
He has some free videos on his site, a YouTube channel answering SQL Performance questions, paid courses and a blog you can subscribe to.
Daily blog, YouTube videos, paid courses, tons of material going back years.
Daily blog again, YouTube videos and courses too
Blog, training, YouTube and comics!
SQL Communities
There is seriously so much content on here, there are the Stairways that teach you specific topics, there are blog posts recommended and shared 3 days a week or weekly. You can get by on this place alone most likely.
Considered the best SQL Conference and it’s held in merry old England, so the only one I’ve been to in-person. They also release all their videos on YouTube a few months after each conference.
Never been due to it being in the US, but heard great things
A SQL Server Internals conference, I haven’t ever worked as a DBA or SRE, so this one is a bit too hardcore for me
There are so many more sources of SQL knowledge, but those are the ones that get most of my attention. If you have any more favourites, drop them in the comments below
Loved your piece on SQL, a programming language I have been meaning to get stuck into :)
useful tips and resources ! i tried w3schools, very practical and also recommend udemy courses and datacamp too ! having a community is quite important to ask questions about a specific question. And cheat sheet helped me a lot during interviews
