███ Description: ███
███ ──────────── ███
███ ███
███ Well start off by discussing the specifics of a topic you might not ███
███ expect handling NULLs! I know it sounds surprising, but its ███
███ important to really understand how to work with NULL values ███
███ especially if you plan to integrate with the Common Language ███
███ Runtime. Next, well address another common and seemingly ███
███ straightforward task the ranking of data. Well explore the specifics ███
███ of how to rank grouped data using some T-SQL functions including ███
███ ROW_NUMBER, RANK, DENSE_RANK, and NTILE. Next well take a look at ███
███ how to identify correlated subqueries and how you can possibly ███
███ replace them with more efficient constructs. Finally, well look at ███
███ an alternative to subqueries, derived tables, and temporary tables ███
███ known as Common Table Expressions, or CTEs, they are similar to ███
███ derived tables but they are self-referencing, can be used numerous ███
███ times within the same query, and can be called recursively! ███
