Get well-versed with ready-to-use techniques for creating high-performance queries and applications. Key Features:. Speed up queries and dramatically improve application performance by both understanding query engine internals and practical query optimizationUnderstand how the query optimizer worksLearn about intelligent query processing and what is new in SQL Server 2022. Book Description:. SQL Server is a relational database management system developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications.

This book starts by describing the inner workings of the query optimizer, and will enable you to use this knowledge to write better queries and provide the query engine with all the information it needs to produce efficient execution plans. As you progress, you'll get practical query optimization tips for troubleshooting underperforming queries. The book will also guide you through intelligent query processing and what is new in SQL Server 2022. Query performance topics such as the Query Store, In-Memory OLTP and columnstore indexes are covered as well. By the end of this book, you'll be able to get the best possible performance for your queries and applications. What You Will Learn:. Troubleshoot queries using methods including extended events, SQL Trace, and dynamic management viewsUnderstand how the execution engine and query operators workSpeed up queries and improve app performance by creating the right indexesDetect and fix cardinality estimation errors by examining query optimizer statisticsMonitor and promote both plan caching and plan reuse to improve app performanceTroubleshoot and improve query performance by using the Query StoreImprove the performance of data warehouse queries by using columnstore indexesHandle query processor limitations with hints and other methods. Who this book is for:. This book is for SQL Server developers who are struggling with slow query execution, database administrators who are tasked with troubleshooting slow application performance, and database architects who design SQL Server databases in support of line-of-business and data warehousing applications.

The SQL Server Query Optimizer is perceived by many to be a magic black box, transforming SQL queries into high performance execution plans in the blink of an eye through some unknowable process. The truth is that, while the Query Optimizer is indeed the highly-complex result of decades of research, learning how it works its magic is not only possible, but immensely useful to database developers and administrators alike.

A better understanding of what the Query Optimizer does behind the scenes can help you to improve the performance of your databases and applications, and this book explains the core concepts behind how the SQL Server Query Optimizer works. With this knowledge, you'll be able to write superior queries, provide the Query Optimizer with all the information it needs to produce efficient execution plans, and troubleshoot the cases when the Query Optimizer is not giving you the best plan possible. With over 15 years of experience in the use of Relational Databases (including SQL Server since version 6.5), Benjamin has watched the SQL Server Relational Engine grow and evolve. His insight will leave you with an excellent foundation in the practicalities of the Query Optimizer, and everything you need to know to start tuning your queries to perfection.
