Query and modify data effectively with the latest T-SQL features.

Master Transact-SQL’s fundamentals, and write correct, robust code for querying and modifying data with modern Microsoft data technologies, including SQL Server 2022, Azure SQL Database, and Azure SQL Managed Instance. Long-time Microsoft Data Platform MVP Itzik Ben-Gan explains key T-SQL concepts, helping you apply your knowledge with hands-on exercises. Ben-Gan first introduces T-SQL’s theory and underlying logic, illuminating it as both a language and a way of thinking. Next, he walks through core topics, including logical query processing, single table queries, joins, subqueries, table expressions, set operators, data analysis, data modifications, temporal tables, and transactions and concurrency. Building on this foundation, you’ll enhance your coding capabilities, from programmatic constructs to the powerful new SQL Graph. Throughout, Ben-Gan presents reusable T-SQL sample code that works in cloud, on-premises, and hybrid environments.

Starting with the background to T-SQL querying and programming, including: logical query processing, book-querying constructs (single table queries, joins, subqueries, table expressions, set operators, data analysis), data modifications, temporal tables, transactions and concurrency, SQL Graph (completely new to this edition), as well as programmatic T-SQL constructs. The book includes extensive exercises and solutions with explanations, allowing the reader to practice what they've learned.

This book is widely considered as the authoritative guide on T-SQL fundamentals. It focuses on understanding why things work the way they do, and not just how to make them work. When people understand the "why" the code they write tends to be more correct and more meaningful. This edition of the book includes coverage of the newest T-SQL additions up to and including SQL Server 2022.
