A Hands-On Approach for Beginners
Businesses are gathering data today at exponential rates and yet few people know how to access it meaningfully. If you’re a business or IT professional, this short hands-on guide teaches you how to pull and transform data with SQL in significant ways. You will quickly master the fundamentals of SQL and more » learn how to create your own databases.
Author Thomas Nield provides exercises throughout the book to help you practice your newfound SQL skills at home, without having to use a database server environment. Not only will you learn how to use key SQL statements to find and manipulate your data, but you’ll also discover how to efficiently design and manage databases to meet your needs.
You’ll also learn how to:
* Explore relational databases, including lightweight and centralized models
* Use SQLite and SQLiteStudio to create lightweight databases in minutes
* Query and transform data in meaningful ways by using SELECT, WHERE, GROUP BY, and ORDER BY
* Join tables to get a more complete view of your business data
* Build your own tables and centralized databases by using normalized design principles
* Manage data by learning how to INSERT, DELETE, and UPDATE records « less
Many SQL texts attempt to serve as an encyclopedic reference on SQL syntax -- an approach that is often counterproductive, because that information is readily available in online references published by the major database vendors.
For SQL beginners, it’s more important for a book to focus on general more » concepts and to offer clear explanations and examples of what various SQL statements can accomplish. This is that book.
A number of features make The Language of SQL unique among introductory SQL books.
First, you will not be required to download software or sit with a computer as you read the text. The intent of this book is to provide examples of SQL usage that can be understood simply by reading.
Second, topics are organized in an intuitive and logical sequence. SQL keywords are introduced one at a time, allowing you to grow your understanding as you encounter new terms and concepts.
Finally, this book covers the syntax of three widely used databases: Microsoft SQL Server, MySQL, and Oracle. Special “Database Differences” sidebars clearly show you any differences in syntax among these three databases, and instructions are included on how to obtain and install free versions of the databases.
This is the only book you need to gain a quick working knowledge of SQL and relational databases.

How to Write Accurate SQL Code
SQL is full of difficulties and traps for the unwary. You can avoid them if you understand relational theory, but only if you know how to put that theory into practice. In this book, Chris Date explains relational theory in depth, and demonstrates through numerous examples and exercises how you can apply more » it to your use of SQL.
This third edition has been revised, extended, and improved throughout. Topics whose treatment has been expanded include data types and domains, table comparisons, image relations, aggregate operators and summarization, view updating, and subqueries. A special feature of this edition is a new appendix on NoSQL and relational theory.
* Could you write an SQL query to find employees who have worked at least once in every programming department in the company? And be sure it’s correct?
* Why is proper column naming so important?
* Nulls in the database cause wrong answers. Why? What you can do about it?
* How can image relations help you formulate complex SQL queries?
* SQL supports "quantified comparisons," but they’re better avoided. Why? And how?
Database theory and practice have evolved considerably since Codd first defined the relational model, back in 1969. This book draws on decades of experience to present the most up to date treatment of the material available anywhere. Anyone with a modest to advanced background in SQL can benefit from the insights it contains. The book is product independent. « less
