This book will be a useful guide to learning the art of writing efficient T-SQL code in modern SQL Server versions, as well as the Azure SQL Database.\u003c\/p\u003e\n\u003cp\u003eThe book will get you started with query processing fundamentals to help you write powerful, performant T-SQL queries. You will then focus on query execution plans and learn how to leverage them for troubleshooting. In the later chapters, you will learn how to identify various T-SQL patterns and anti-patterns. This will help you analyze execution plans to gain insights into current performance, and determine whether or not a query is scalable. You will also learn to build diagnostic queries using dynamic management views (DMVs) and dynamic management functions (DMFs) to address various challenges in T-SQL execution. Next, you will study how to leverage the built-in tools of SQL Server to shorten the time taken to address query performance and scalability issues. In the concluding chapters, the book will guide you through implementing various features, such as Extended Events, Query Store, and Query Tuning Assistant using hands-on examples.\u003c\/p\u003e\n\u003cp\u003eBy the end of this book, you will have the skills to determine query performance bottlenecks, avoid pitfalls, and discover the anti-patterns in use.\u003c\/p\u003e\n\u003cp\u003eForeword by Conor Cunningham, Partner Architect – SQL Server and Azure SQL – Microsoft\u003c\/p\u003eWhat you will learn\u003cul\u003e\n\u003cli\u003eUse Query Store to understand and easily change query performance\u003c\/li\u003e\n\u003cli\u003eRecognize and eliminate bottlenecks that lead to slow performance\u003c\/li\u003e\n\u003cli\u003eDeploy quick fixes and long-term solutions to improve query performance\u003c\/li\u003e\n\u003cli\u003eImplement best practices to minimize performance risk using T-SQL\u003c\/li\u003e\n\u003cli\u003eAchieve optimal performance by ensuring careful query and index design\u003c\/li\u003e\n\u003cli\u003eUse the latest performance optimization features in SQL Server 2017 and SQL Server 2019\u003c\/li\u003e\n\u003cli\u003eProtect query performance during upgrades to newer versions of SQL Server\u003c\/li\u003e\n\u003c\/ul\u003eWho this book is for\u003cp\u003eThis book is for database administrators, database developers, data analysts, data scientists, and T-SQL practitioners who want to get started with writing T-SQL code and troubleshooting query performance issues, through the help of practical examples.
