Free Resources to learn SQL

[u/Any-Froyo8528]

Hello Everyone
I’m a recent Graduate and I just want to learn SQL. I started watching YouTube tutorials and I never finished it. And recently I started learning on SQLZOO which was good but I didn’t finished even that. And today I went through Codedex SQL tutorial it was too good and after finishing the chapter one they asking me to pay to finish all the chapters

So I need any resource which will be fun finishing all chapter (like codedex) and help me to learn SQL.

And please give me any suggestions how to concentrate while learning SQL, POWER Bi

Thank you

Most questions are not free

I created sqlshed.com which uses duckdb (a web assembly version that runs completely on your client side). It has lessons but also practice data sets for trying queries out on new data sets.

I'm just now showing it to the world so I'd appreciate any feedback

Looks awesome!!

It’s not a full-fledged learning platform, but if you’d like a little quick SQL puzzle per day, I’m building sqlsip.com. And I’ve attached an SQL joins guide, in case it is helpful. SQL is such a useful skill! Happy learning :)

Don’t forget you can spin up your own cloud hosted SQL database with the Azure free tier as well over at https://aka.ms/trySQL

Get some cloud, SQL and add some Power BI on your resume and you’ll be top of the pack.
