"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
