Ask HN: Best book to learn about SQL and databases?

I like Practical SQL from No Starch Press: https://nostarch.com/practicalSQL

I didn't learn from the book myself, but I read it to evaluate it as a teaching tool for juniors and wound up recommending it.

I took Neil Sainsbury’s Mastery with SQL course and would recommend it.

To add to suggestions of others, the SQL Antipatterns was also an insigtful read about basic pitfalls of db design.

I have also found first chapters from Designing Data Intensive Applications helpful to get context around sql/nosql dbs.
