Overview

Apply powerful window functions in T-SQL—and increase the performance and speed of your queries

Optimize your queries—and obtain simple and elegant solutions to a variety of problems—using window functions in Transact-SQL. Led by T-SQL expert Itzik Ben-Gan, you'll learn how to apply calculations against sets of rows in a flexible, clear, and efficient manner. Ideal whether you're a database administrator or developer, this practical guide demonstrates ways to use more than a dozen T-SQL querying solutions to address common business tasks.

  • Go beyond traditional query approaches to express set calculations more efficiently
  • Delve into ordered set functions such as rank, distribution, and offset
  • Implement hypothetical set and inverse distribution functions in standard SQL
  • Use strategies for improving sequencing, paging, filtering, and pivoting
  • Increase query speed using partitioning, ordering, and coverage indexing
  • Apply new optimization iterators such as Window Spool
  • Handle common issues such as running totals, intervals, medians, and gaps
