For data analysis and beyond
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.
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.
