This is a fantastic book! It has more info than books at twice the cost, but it presents that info in a concise, digestible manner. I wish I had a resource like this when I was first starting with MySQL."

What you’ll learn in this book
Section 1: An introduction to MySQL
In this section, you’ll build a solid foundation by learning the concepts and terms for working with any relational database. In addition, you’ll learn how to use MySQL Workbench to code and run the basic SQL statements for retrieving, adding, updating, and deleting data in a MySQL database. When you’ve completed this section, you’ll be able to continue with any of the other sections in the book.
Section 2: More SQL skills as you need them
This section presents advanced SQL skills for retrieving data from a database including features like summary queries, subqueries, data types, and functions. And the chapters in this section are modular, so you can read them in whatever sequence you prefer.
Section 3: Database design and implementation
This section shows how to design a database and how to implement that design either by coding SQL statements or by using MySQL Workbench. When you’re done, you’ll be able to design and implement your own databases. In addition, this section shows how to create and use views to simplify data access and improve data security.
Section 4: Stored program development
This section takes you from being a good MySQL programmer to a great one by teaching you how to create stored programs. Here, you’ll learn how to use create stored procedures that use MySQL’s procedural language to manage transactions and locking. In addition, you’ll learn how to create user-defined functions, triggers, and events.
Section 5: Database administration
In this section, you’ll learn a starting set of skills for becoming a database administrator (DBA). First, you’ll learn how to secure, back up, and restore a database that’s running on a local server. Then, you’ll learn how to perform most of the same skills on a MySQL database that’s running remotely on Amazon’s cloud computing platform, AWS.
Who this book is for
This book is for anyone who wants to learn how to work with a MySQL database, regardless of prior programming experience. This includes…
- Anyone who wants to learn how to use SQL to work with relational databases
- Developers who need to write SQL to retrieve and update data in a database
- Data analysts and scientists who need to retrieve and analyze the data in a database
- Experienced developers who want to write SQL statements that work and perform better
- Web developers who need a way to organize large amounts of data and quickly serve it to users
- Developers who are interested in becoming a database administrator (DBA)
Why you'll learn faster and better with this book
Like all our books, this book is designed to make it as easy as possible for you to learn new skills faster and retain them better. Here are a few of those features:
- All of the information is presented in paired pages, with the essential syntax, guidelines, and examples on the right page and clear explanations on the left page. This helps you learn faster by reading less.
- The paired-pages format is ideal for reference when you need to refresh your memory about how to do something.
- The hundreds of examples present usable code for tasks that you’re likely to need for your own queries.
- The exercises at the end of each chapter provide a way for you to gain valuable hands-on experience without any extra busywork.
What software you need
Although you can use this book with most versions of MySQL, we recommend that you use:
- MySQL Community Server 8.0 or higher
- MySQL Workbench 8.0 or higher
This software can be downloaded for free from MySQL’s website, and appendixes A (Windows) and B (macOS) provide complete instructions for installing it.
What's new in this edition
- This book has been updated to MySQL 8.0.33, removing deprecated data types and functions and adding new statement options and clauses.
- Cloud computing, now a fundamental part of the online database landscape, has been given its own chapter, including step-by-step instructions for hosting a MySQL database using Amazon Web Services (AWS).
- Improved text and code examples make the book more comprehensive and easier to understand and use than ever.
What people say about this book
"A very solid book with plenty of breadth and lots of examples. As a developer with almost 10 years of MySQL experience, I still picked up a lot of new detail on things I thought I knew."
- David Bolton, C/C++/C# Guide, About.com
"I was amazed at how much information was packed into this book. The style of the book made it really easy to read and understand the information.... I learned a lot of new MySQL ideas reading this book, and I will be using it frequently as a reference."
- Paul Turpin Southeastern Inter-Relational Database Users Group
"If you ever want to learn to use MySQL, write SQL queries, create database elements, then this is the book to pick up. Rating: 10 Horseshoes."
- Review by Mohamed Sanaulla, JavaRanch.com
“Overall the book packs in a lot of material and moves very quickly from introductory to more advanced topics. The chapters on queries for example work really well even if you’re not using MySQL — those sections of the book can stand alone as a highly effective introduction to SQL. […] All in all, this is very highly recommended — one of the best MySQL books on the market.”
- Pan Pantziarka, www.techbookreport.com
"I’ve found that many technical books go into laborious details that make them difficult to read, let alone use, but Murach’s MySQL has already proven to be helpful in solving several challenges I’ve encountered on my current MySQL project.... One thing I enjoyed is that it’s well-indexed, and the material itself is concise, with stand-alone, real-world examples.... It’s not theoretical, it’s practical, and presents topics in a friendly style that can be consumed painlessly, a few chapters at a time.”
- Posted at an online bookseller
“Beautifully written, and encyclopedic. Concepts are presented on facing pages with explanation on left and examples/visuals on right. I’m constantly referring to it - and find it easy to use as a quick reference.”
- Posted at an online bookseller
"I found this to be a great introductory book to MySQL.... The examples make it easy to quickly see the differences between the database system you have been working on and how to do the same thing in MySQL. Because of this book, I know that I could easily transition my skills in developing, managing, and designing an Oracle database application to a MySQL database system."
- Eric "Morty" Mortensen, Northeast Ohio Oracle Users Group
"I love this book and refer back to it almost weekly."
