This is one of the better computer manuals for the beginner/general public that I have encountered. The pace is good and fast but he explains everything you need to know in detail -- once. With a big bold heading so you don't miss it. The examples and the writing are crisp and to the point. The code is easy to download and obtain.

I first worked through this book on my public library's subscription to the online edition when I realized this was one I needed to buy because I go back to it so much.

I also want to add that the physical book is very well made. It holds up to a lot of abuse, has thick pages, good type, and is very well bound. You can spill a full cup of coffee on the thing, you can bend it backwards while reading on the couch with one hand, you can write in black ink all over the pages -- I have done all these things and the book is very much intact. Tough paper and very tough, nearly waterproof cover. I usually feel ripped off when I buy a new book, but not this time.

I tried several "beginner" SQL books, and this one is a keeper. Of all the books out there, this one has practical exercises throughout that are easy to follow and logically progress, and best of all they work flawlessly! The writer of this book took the time and effort to clearly document the steps necessary to install and use PostgreSQL, and consequently I was able to easily install my PostgreSQL instance and do all the practical exercises, which is essential to learning.

I appreciate the way DeBarros has written this book in such a way that it breaks down complex concepts into manageable and clear explanations. DeBarros offers numerous real-world examples that demonstrate how SQL can be used to solve everyday data problems. Each chapter builds on the previous one, gradually introducing more advanced topics while reinforcing foundational skills.

Definitely recommend for those interested in learning SQL.

I just completed my master's program in Data Science and I can honestly say that this is the BEST text book I have read throughout my ENTIRE collegiate career. I wish I had read Chapter 11 on statistics in the start of my career because now I completely understand it. Ugh, you live and you learn.

I am almost done with reading this book and I am giving it 4 stars instead of 5 because it is very wordy. Which ends up making the text seem boring in a sense. However, I do not think this book was written for people like me who would have preferred the text to go through more of the database design process than data manipulation. Hence I assume that this book would fit a data science quite well but a dev trying to quickly learn a stack before graduation not so much.

Would I buy it again? => Nope, I would go for a thinner quicker read. But I am going to keep it and use it as a reference to any future data manipulation.

Great book learned so much!

This book is excellent for beginners to SQL. I already had a solid foundation, but reading through from beginning to end, I learned quite a lot. The author explains concepts in great detail with clear examples.

I highly recommend this to anyone who wants to learn SQL, or just to have as a quick reference for any of the concepts within.

Excellent book, specially if you are looking for a career in Cybersecurity.

Very good

Great

We know it's old but still relevant

Well written

The book is very easy to read and follow. Although it uses PosgresSQL (which is very good and I recommend to use) the author uses examples for SQL Standard which makes this book a good source of information for any SQL language such as MYSQL.

In case you don't use PostgresSQL I recommend you to review at the same time the documentation of the other language you are using, so it will be easier for you to associate the concepts that come in the book.

If you already have some experience in school and want to go deeper into databases, this book will give you a very good foundation or at least serve to revisit it every time you want to reinforce a topic.

In general, it is a good book for beginners or people who want to reinforce their basics.
