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. 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

Query and modify data effectively with the latest T-SQL features

Master Transact-SQL's fundamentals, and write correct, robust code for querying and modifying data with modern Microsoft data technologies, including SQL Server 2022, Azure SQL Database, and Azure SQL Managed Instance. Long-time Microsoft Data Platform MVP Itzik Ben-Gan explains key T-SQL concepts, helping you apply your knowledge with hands-on exercises. Ben-Gan first introduces T-SQL's theory and underlying logic, illuminating it as both a language and a way of thinking. Next, he walks through core topics, including logical query processing, single table queries, joins, subqueries, table expressions, set operators, data analysis, data modifications, temporal tables, and transactions and concurrency. Building on this foundation, you'll enhance your coding capabilities, from programmatic constructs to the powerful new SQL Graph. Throughout, Ben-Gan presents reusable T-SQL sample code that works in cloud, on-premises, and hybrid environments.

For IT Professionals and Consultants

In Advanced Transact-SQL for SQL Server 2000, authors Itzik Ben-Gan and Thomas Moreau explore the powerful capabilities of Transact-SQL (T-SQL). Ben-Gan and Moreau offer solutions to common problems encountered using all versions of SQL Server, with a focus on the latest version, SQL Server 2000.

Expert tips and real code examples teach advanced database programmers to write more efficient and better-performing code that takes full advantage of T-SQL. The authors offer practical solutions to the everyday problems programmers face and include in-depth information on advanced T-SQL topics such as joins, subqueries, stored procedures, triggers, user-defined functions (UDFs), indexed views, cascading actions, federated views, hierarchical structures, cursors, and more.

Effectively query and modify data using Transact-SQLMaster T-SQL fundamentals and write robust code for Microsoft SQL Server and Azure SQL Database. Itzik Ben-Gan explains key T-SQL concepts and helps you apply your knowledge with hands-on exercises. The book first introduces T-SQL’s roots and underlying logic. Next, it walks you through core topics such as single-table queries, joins, subqueries, table expressions, and set operators. Then the book covers more-advanced data-query topics such as window functions, pivoting, and grouping sets. The book also explains how to modify data, work with temporal tables, and handle transactions, and provides an overview of programmable objects.
