Use window functions to write simpler, better, more efficient T-SQL queries  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.Youll find a detailed section on optimization, plus an extensive collection of business solutionsincluding 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 predicatesMaster essential SQL windowing concepts, and efficiently design window functionsEffectively utilize partitioning, ordering, and framingGain
