Murach’s SQL Server 2019 for Developers
When we published the first edition of this book, we heard from plenty of people who thought it was a great way to learn SQL Server from scratch. But we also heard from a lot of experienced developers who read it and were amazed to discover how much they didn’t know about SQL. That’s why we’ve dubbed this book "the SQL book that most developers don’t even know they need."

Although I have used SQL Server on a daily basis for over 15 years, I was amazed at the number of new things that I learned while reading this book. I used a couple of the ideas to create a noticeable improvement in response time for one of my client/server projects."

What you'll learn in this book
Section 1: An introduction to SQL
In this section, you’ll learn the concepts and terms you need for working with any relational database. You’ll also learn how to use Microsoft SQL Server 2019 and the Management Studio to run SQL statements on your own computer.
Section 2: The essential SQL skills
In this section, you’ll learn all the skills for retrieving data from a database and for adding, updating, and deleting that data. These skills move from the simple to the complex so you won’t have any trouble if you’re a SQL novice. And they present skills like using outer joins, summary queries, and subqueries that will raise your SQL expertise if you already have SQL experience.
Section 3: Database design and implementation
In this section, you’ll learn how to design a database and how to implement that design by using either SQL statements or the Management Studio. When you’re done, you’ll be able to design and implement your own databases. But even if you’re never called upon to do that, this section will give you the perspective that will make you a better SQL programmer.
Section 4: Advanced SQL skills
In this section, you’ll learn the skills for working with database features like views, scripts, stored procedures, functions, triggers, cursors, and transactions. You’ll also learn how to manage database security, and you’ll learn how to use the features for working with XML and BLOB data. These are the features that give a database management system much of its power.
Who this book is for
Application developers
I think it’s fair to say that most developers don’t know enough about SQL and the database management system they’re using. As one customer put it, "I know just enough about SQL Server to be a little bit dangerous!"
That’s why developers often code SQL statements that don’t perform as efficiently as they ought to. That’s why they aren’t able to code some of the queries that they need for their applications. And that’s why they don’t take advantage of all the features that SQL Server has to offer.
That’s also why this book should be required reading for every application programmer who uses SQL Server.
Anyone who wants to become a database administrator
This book is also the right first book for anyone who wants to become a database administrator. Although this book doesn’t present all of the skills that are needed by a DBA, it will get you started. Once you’ve finished it, you’ll be prepared for more advanced books on the subject.
Anyone who wants to learn standard SQL
SQL is a standard language for accessing database data. So most of the SQL code in this book will work with any database management system. As a result, once you use this book to learn how to use SQL to work with a SQL Server database, you can transfer most of what you have learned to another DBMS such as Oracle, DB2, or MySQL.
What the prerequisites are
There aren't any.
Although you will progress through this book more quickly if you have some development experience, everything you need to know about databases and SQL is presented in this book.
What software you need
Operating system
- Windows 10 or later
For all chapters
To work with SQL Server as shown in this book, you can download all the software you need from Microsoft’s website for free. That includes:
- SQL Server 2019 Express
- SQL Server Management Studio
In appendix A in the book, you’ll find complete instructions for installing these items on your computer. And in chapter 2, you’ll learn how to use them.
For chapter 19
To use C# or Visual Basic to work with BLOBs as shown in chapter 19, you can use:
- Visual Studio Community
This is available from Microsoft’s website for free, and appendix A shows how to install it.
What people say about this book
"Looking to get started with SQL Server? This is a fantastic place to start. Looking for a solid reference as you polish your SQL? Grab a copy."
--Stephen Wynkoop, SQL Server Worldwide Users Group
"The Perfect Book for Application Programmers: If you’re new to using SQL Server in your applications, this book will save you a lot of time. It teaches you about SQL, database design, a lot about admin (which many developers have to do; not everywhere has dedicated DBAs), and the advanced SQL is excellent. Highly recommended."
--David Bolton, Software Developer/Technical Writer and Reviewer
"Although I have used SQL Server on a daily basis for over 15 years, I was amazed at the number of new things that I learned while reading this book. I used a couple of the ideas to create a noticeable improvement in response time for one of my client/server projects."
--Brian Mishler, Orlando .NET User Group
"The most positive feature of the book is the simple informative writing. Wow! I think a lot of thought went into this book before they ever wrote a word."
--Michael Robbins, Denver Visual Studio .NET Users Group
"There are areas where I am an expert and other areas that I have picked up enough to just be ‘a little bit dangerous.’ SQL Server was one of the latter areas, and I wanted to round out my knowledge, and this book proved to be the perfect tool…."
--Posted at an online bookseller
"I have recommended this book and others in the series to developers and architects as an outstanding reference for application and database development."
--Eric Nothiesen, Enterprise Developers Guild
"This book exceeds my expectations for books that teach database and software development. A wonderful book for both learning and mastering SQL Server."
