Learning SQL for free

Transcript

I don't get why more CS students don't focus on learning SQL. It literally only has like 10 main commands and companies pay you the big bucks to know it. So here's how you can learn it in a weekend for free. You're going to go to this site called DataLemur. It's completely free and it teaches you step-by-step how to learn SQL. On top of that, it gives you free practice questions that big tech companies actually use for interviews. Because honestly, the hardest part of learning SQL is just creating your own dummy data to put into the tables for you to practice with. DataLemur just takes care of that. It also does have a paid version, but you can literally learn everything with the free one. Then if you really want to show something on your resume, you can go to build your own X and create a data pipeline or pay actual money to get a certification to put on your resume.
