Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

This 1967 film is widely regarded as one of the best American movies ever made. Now remembered almost as much for its Simon and Garfunkel music as its deadpan comedy and being the role that established Dustin Hoffman as the hottest actor in Hollywood. It became a cultural icon for capturing the spirit of 60s angst of a young man on the make, while garnering a batch of Oscar nominations. After watching the movie on your own, join us to relive (or experience!) those feelings at our discussion.
