T-SQL Window Functions

<b>Use window functions to write simpler better more efficient T-SQL queries </b></p> 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.</p> </p> </p> <b>Microsoft MVP Itzik Ben-Gan shows how to: </b></p> - Use window functions to improve queries you previously built with predicates </p> - Master essential SQL windowing concepts and efficiently design window functions </p> - Effectively utilize partitioning ordering and framing </p> - Gain practical in-depth insight into window aggregate ranking offset and statistical functions </p> - Understand how the SQL standard supports ordered set functions and find working solutions for functions not yet available in the language </p> - Preview advanced Row Pattern Recognition (RPR) data analysis techniques </p> - Optimize window functions in SQL Server and Azure SQL Database making the most of indexing parallelism and more </p> - Discover a full library of window function solutions for common business problems </p> </p> <b>About This Book </b></p> - For developers DBAs data analysts data scientists BI professionals and power users familiar with T-SQL queries </p> - Addresses any edition of the SQL Server 2019 database engine or later as well as Azure SQL Database </p> </p> <b>Get all code samples at: </b></p> MicrosoftPressStore.com/TSQLWindowFunctions/downloads </p>
