What Students Are Saying

Loved it! Jose is a great instructor who has taught me a lot in his other courses; I bought this because of the positive experiences from those courses. I was not disappointed in the Complete SQL Bootcamp. :) thanks Jose, I appreciate you!

John Carmack

While I have known SQL for a little while, it's good to finally have something to prove it! This was a great course provided by Jose Portilla. I recommend this to anyone who wants to brush up on their SQL or to learn PostgreSQL from scratch.

Great so far. Excellent teaching. Also helps that we can pause and rewind. Very well explained. Great pace. Not too fast or slow.

Victor Adra

The detailed explanation would help anyone learn SQL from Scratch. Your efforts are much appreciated.

Maximillian Hill

Really enjoyed this course. Went into it having meant to learn SQL for years but not knowing a great deal and came out of it feeling pretty knowledgeable and confident. A good mix of theory and practice means the course always feels useful and comprehensive in its scope.

Neil Leggett

I have less than zero SQL experience and am loving this course so far. It's very clear and easy to follow. Thank you!

Kimberly Thrush

I'm halfway there through the course and as for now I have to say it's amazing. I did one other beginner course on SQL and it was nowhere near as good as this. This one is very professional and understandable. The quality of materials and presentations is simply superb. I can't stop watching it!

Krzysztof Drzewiński

I like the hands-on ability to create databases and learn queries by doing in Postgres SQL that can be used for projects.
