Learning SQL by Alan Beaulieu

Product Details

About the Book

Learning SQL has become one of the definitive introductory guides for anyone who needs to work with relational databases. As data floods into every organization, SQL remains the essential tool for putting that data to work, and author Alan Beaulieu — a database consultant with over 25 years of experience — helps developers, administrators, and analysts get up to speed with SQL fundamentals for writing database applications, performing administrative tasks, and generating reports.

The book moves readers efficiently through core SQL concepts before advancing into more sophisticated features, covering everything from basic data statements used to generate, manipulate, and retrieve information to SQL schema statements for creating tables, indexes, and constraints. Later chapters explore subqueries, built-in functions, conditional logic, transactions, and — in the latest edition — analytic functions, big data considerations, and techniques for working with very large databases. Each chapter is structured as a self-contained lesson built around a key SQL concept, filled with clear illustrations and thoroughly annotated examples, and followed by exercises that let readers immediately practice and reinforce what they've learned. Whether the goal is writing better queries, managing databases, or building data-driven applications, Learning SQL offers a thorough, practical foundation in one of the most widely used languages in technology.
