One of the best site to learn and review SQL. It is completely practice-oriented rather than theory-based. Additionally, if anyone just wants to practice their SQL skills, this site is perfect, offering many different types of courses.

course was easy to follow and gave examples. Great course for beginners

I find this course a perfect fit for me, particularly given my expertise in R (data.table and dplyr). I breezed through it with joy and ease. It offers rich explanations and testing questions. I highly recommend it, especially for those who began their data journey with R or Python and want to catch up with SQL.

Easy to follow, step by step progression with positive useful interaction every step of the way. Not a lot of dry reading and vocabulary, just actively learning SQL by using it.

Doing the SQL from A-Z course and I am really happy with it. It’s a great way to get to know SQL
