Description
Expert T-SQL Window Functions in SQL Server 2019 focuses on one of the most powerful yet least-known features of the T-SQL language, Window Functions. The author shows how these functions can be used to simplify complex queries and provide a viable alternative to slow, cumbersome loops and self-joins.
By taking an in-depth look at the performance improvements in SQL Server 2019, the book teaches developers and database administrators how to look at data as a collection rather than row by row. This shift in perspective results in code that not only runs faster, but is also much easier to maintain and debug.
