This book helps you write queries that perform fast and deliver results on time. You will learn that query optimization is not a dark art practiced by a small, secretive cabal of sorcerers. Any motivated professional can learn to write efficient queries from the get-go and capably optimize existing queries. You will learn to look at the process of writing a query from the database engine’s point of view, and know how to think like the database optimizer...The book begins with a discussion of what a performant system is and progresses to measuring performance and setting performance goals. It introduces different classes of queries and optimization techniques suitable to each, such as the use of indexes and specific join algorithms. You will learn to read and understand query execution plans along with techniques for influencing those plans for better performance. The book also covers advanced topics such as the use of functions and procedures, dynamic SQL, and generated queries. All of these techniques are then used together to produce performant applications, avoiding the pitfalls of object-relational mappers...What You Will Learn.Identify optimization go | | 出版日期 | Book 20211st edition | | 关键词 | Database Performance; Query Performance; Query Optimization; SQL Performance; SQL Tuning; Optimizing SQL; | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4842-6885-8 | | isbn_ebook | 978-1-4842-6885-8 | | copyright | Henrietta Dombrovskaya, Boris Novikov, Anna Bailliekova 2021 |
