{"product_id":"9780135861448","title":"T-SQL Window Functions: For data analysis and beyond","description":"\u003cb\u003eUse window functions to write simpler, better, more efficient T-SQL queries \u003c\/b\u003e \u003cp\u003e Most T-SQL developers recognize the value of window functions for data analysis calculations. 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.\u003c\/p\u003e \u003cp\u003e\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e\u003cb\u003eMicrosoft MVP Itzik Ben-Gan shows how to: \u003c\/b\u003e\u003c\/p\u003e \u003cp\u003e• Use window functions to improve queries you previously built with predicates \u003c\/p\u003e \u003cp\u003e• Master essential SQL windowing concepts, and efficiently design window functions \u003c\/p\u003e \u003cp\u003e• Effectively utilize partitioning, ordering, and framing \u003c\/p\u003e \u003cp\u003e• Gain practical in-depth insight into window aggregate, ranking, offset, and statistical functions \u003c\/p\u003e \u003cp\u003e• Understand how the SQL standard supports ordered set functions, and find working solutions for functions not yet available in the language \u003c\/p\u003e \u003cp\u003e• Preview advanced Row Pattern Recognition (RPR) data analysis techniques \u003c\/p\u003e \u003cp\u003e• Optimize window functions in SQL Server and Azure SQL Database, making the most of indexing, parallelism, and more \u003c\/p\u003e \u003cp\u003e• Discover a full library of window function solutions for common business problems \u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e\u003cb\u003eAbout This Book \u003c\/b\u003e\u003c\/p\u003e \u003cp\u003e• For developers, DBAs, data analysts, data scientists, BI professionals, and power users familiar with T-SQL queries \u003c\/p\u003e \u003cp\u003e• Addresses any edition of the SQL Server 2019 database engine or later, as well as Azure SQL Database \u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e\u003cb\u003eGet all code samples at: \u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eMicrosoftPressStore.com\/TSQLWindowFunctions\/downloads \u003c\/p\u003e","brand":"Pearson Education","offers":[{"title":"Default Title","offer_id":46232609161457,"sku":"9780135861448","price":53.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/5433\/7265\/files\/9780135861448_p0.jpg?v=1765262351","url":"https:\/\/shop.barnesandnoble.com\/products\/9780135861448","provider":"Barnes \u0026 Noble","version":"1.0","type":"link"}
