Hello Devs! If you're a software engineer, learning SQL (Structured Query Language) is as essential as mastering system design or coding. SQL is the language of data, and in today’s data-driven world, it is one of the most valuable skills you can have.
It doesn’t matter if you're working in Java, Golang, Python, or .NET—sooner or later, you’ll need to interact with a database, and writing SQL queries will become part of your daily workflow.
Many developers assume that knowing how to perform basic operations like SELECT, INSERT, UPDATE, and DELETE is enough.
But is it? What about indexes, query execution plans, normalization, stored procedures, triggers, joins, views, and more? These are the tools that differentiate a novice from a seasoned engineer.
Previously, I shared my list of 10 Must-Read AI and LLM Engineering Books and the best software architecture books like Head First Software Architecture. Today, I'm bringing you a curated list of the best SQL and Database Design books that every software engineer should read to level up their database skills.
I first learned SQL back in college and was instantly drawn to its power and elegance. Writing SQL queries felt like solving logic puzzles—fun, challenging, and immensely rewarding. But like many others, I plateaued quickly because I thought I knew enough.
That illusion was shattered when I joined a project using Sybase for a large-scale financial system. Hundreds of stored procedures, complex joins, and massive datasets made it clear—I had only scratched the surface of what SQL could do.
This list is a result of my journey to go deeper. It includes books on SQL basics, advanced techniques, database design, and normalization—resources that helped me (and can help you) become a truly competent backend or full-stack engineer.
If you prefer learning through video, I highly recommend pairing these books with online courses like The Complete SQL Bootcamp by Jose Portilla on Udemy—an engaging and practical way to master SQL step by step.
Let’s dive in.
6 Must-Read SQL and Database Books for Software Engineers
It doesn't matter whether you are a beginner programmer, have just started your software development career, or are an experienced software professional with years of experience; you will find some of the books refreshing.
You will learn a lot in terms of SQL concepts, database design, and SQL query skills.
So, what are we waiting for? Let's start with this list.
1. SQL Performance Explained by Markus Winand
This is one of my favorite SQLs and definitely a must-read for every developer.
If I say that whatever I know about SQL indexes is due to this book, then it won't be wrong. I had a lot of misconceptions about database indices and didn't know how their order could affect performance.
I didn't even know what a table scan, an index scan, or index seeks were (https://www.java67.com/2017/12/difference-between-table-scan-index.html), and, in general, how an index works in SQL in detail until I learned how indexing works and how it affects query performance.
This is an excellent book by Markus Winand, and I thank him for explaining such an essential topic in great detail. One of the must-read SQL books for every programmer.
2. Joe Celko's SQL for Smarties: Advanced SQL Programming (The Morgan Kaufmann Series in Data Management Systems
I didn't know about this book until last year, but ever since I came to know about it, I just fell in love. It's a great book to improve your SQL query skills.
I always like to solve SQL query-based problems because they are also an excellent exercise for your mind, and this book is full of such problems.
The book is advanced, and some of the problems are tough even for seasoned SQL programmers. Even though you will solve the problem, a good chance that you will also learn a new way to answer the same question by reading explanations.
In short, one of the best SQL books for experienced programmers who want to improve their SQL query skills.
3. SQL Antipatterns, Volume 1: Avoiding the Pitfalls of Database Programming
To be successful, it's not just essential to do the right things, but it is also necessary to avoid mistakes that can hamper your success. This universal truth is also applicable to SQL.
It's just not enough to know all the best practices in the SQL world and keep repeating silly mistakes like using a SELECT * query or having duplicate columns.
This book will help you avoid the common mistakes every SQL developer makes. If you don't know about SQL mistakes, this is also an excellent book to learn about them. Again, one of the must-read SQL books for programmers who are serious about improving their SQL and database design skills.
If you are learning SQL for data science, then I also suggest you check out this SQL for Data Science course on Udemy, which will teach you how to understand and write large queries, which you often need while working with real-world data.
4. Head First SQL
This is the best book for SQL beginners. I like the Head First style for their innovative teaching with diagrams, fireside chats, puzzles, explanations, and highlighting the most important concepts.
I have been recommending this book to beginner programmers for years, and they always thank me for that.
You can use this book for theory, for example, and understanding fundamental concepts of SQL, like Joins, Subqueries, Normalization, and a little bit of database design.
If you are an active learner like me, then you can also combine this book with The Complete SQL Bootcamp: Go From Zero To Hero course by Jose Pottila on Udemy, which is full of hands-on SQL exercises and lectures.
By the way, the second edition of Head First SQL is also coming soon, but until then, you can start with the first edition itself.
5. Practical SQL: A Beginner's Guide to Storytelling with Data By Anthony DeBarros (2nd Edition)
This SQL book is for those interested in using SQL for data analysis and storytelling. It teaches how to analyze real datasets, uncover insights, and present findings effectively.
What you'll learn:
- Understand the fundamentals of relational databases and SQL
- Work with real-world datasets, including US Census data and NYC taxi rides
- Perform data cleaning, aggregation, and filtering in PostgreSQL
- Use SQL functions and joins to derive insights
- Learn best practices for data visualization and reporting
Practical SQL is especially useful for data engineers, data analysts, and software engineers who want to use SQL for data-driven decision-making.
6. Learning SQL: Generate, Manipulate, and Retrieve Data (3rd Edition)
If you're new to SQL or want to sharpen your fundamentals, “Learning SQL” by Alan Beaulieu is a top pick, often recommended by developers on Reddit, Hacker News, and Stack Overflow.
This third edition offers a friendly yet thorough guide to writing queries, creating and modifying tables, and handling real-world database tasks. It also includes newer material on big data and analytic functions.
Why it's worth reading:
- Clear examples with annotated explanations
- Hands-on practice at the end of each chapter
- Great for developers, analysts, and data scientists
- Self-paced learning that builds from basics to advanced use
Pair it with the SQL for Newbs: Data Analysis for Beginners course on Udemy for a hands-on experience.
That's all in this list about 6 Timeless SQL Books for Software Engineers and Data Engineers. To be honest, it's easy to learn SQL, but it's tough to master it; that's why books like SQL Performance Explained and SQL Anti-Patterns are significant for both SQL developers and Java/C# developers who deal with databases and SQL.
P. S. --- If you are looking for an online course to learn SQL in depth, then I also suggest you check out Colt Steele's The Ultimate MySQL Bootcamp: Go from SQL Beginner to Expert* course on Udemy.
And, if you haven't read, you can also read 10 Must Read Software Engineering Books for Developers and 10 Must Read Algorithms Books I shared earlier. It contains books on software engineering, data structures, and algorithms for software engineers and developers.
All the best with your SQL journey !!
