But they can do far more, and recent optimizations make them even more powerful. In T-SQL Window Functions, renowned T-SQL expert Itzik Ben-Gan introduces breakthrough techniques for using them to handle many common T-SQL querying tasks with unprecedented elegance and power. Using extensive code examples, he guides you through window aggregate, ranking, distribution, offset, and ordered set functions. You'll find a detailed section on optimization, plus an extensive collection of business solutions -- including novel techniques available in no other book.Microsoft MVP Itzik Ben-Gan shows how to: - Use window functions to improve queries you previously built with predicates - Master essential SQL windowing concepts, and efficiently design window functions - Effectively utilize partitioning, ordering, and framing - Gain practical in-depth insight into window aggregate, ranking, offset, and statistical functions - Understand how the SQL standard supports ordered set functions, and find working solutions for functions not yet available in the language - Preview advanced Row Pattern Recognition (RPR) data analysis techniques - Optimize window functions in SQL Server and Azure SQL Database, making the most of indexing, parallelism, and more - Discover a full library of window function solutions for common business problems About This Book - For developers, DBAs, data analysts, data scientists, BI professionals, and power users familiar with T-SQL queries - Addresses any edition of the SQL Server 2019 database engine or later, as well as Azure SQL Database Get all code samples at: MicrosoftPressStore.com/TSQLWindowFunctions/downloads", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/0/13/586/144/0135861446_b.jpg", "price_data" : { "retail_price" : "39.99", "online_price" : "39.99", "our_price" : "39.99", "club_price" : "39.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
