"More fun and more engaging [than Learning SQL from O'Reilly]."
Giles McMullen-Klein, Python Programmer, YouTuber

Practical SQL will take you from an absolute databases beginner towards becoming a database and SQL master. This book is one of those books that you feel like [you're] reading a novel, not a technical book. It uses an easy to follow and [understandable] approach that makes it easy to read for people from all backgrounds.
Sara A. Metwalli, Towards Data Science

"I recommend reading Practical SQL by Anthony DeBarros for a more in-depth look on how to implement regression analysis and other analytical tools using SQL."

"One of the most interesting books about SQL I've ever read. At first glance, it looks like a guide for complete rookies. But the author raises topics that will interest advanced users."
