T-SQL Querying

Tackle the toughest set-based querying and query tuning problems—guided by an author team with in-depth, inside knowledge of T-SQL. Deepen your understanding of architecture and internals—and gain practical approaches and advanced techniques to optimize your code’s performance.



Discover how to:





Move from procedural programming to the language of sets and logic
Optimize query tuning with a top-down methodology
Assess algorithmic complexity to predict performance
Compare data-aggregation techniques, including new grouping sets
Manage data modification—insert, delete, update, merge—for performance
Write more efficient queries against partitioned tables
Work with graphs, trees, hierarchies, and recursive queries
Plus—Use pure-logic puzzles to sharpen your problem-solving skills
