Bring a friend, bring family, and bring that neighbor that you kinda know... Come one, come all for some free table tennis. Note: Because we have been playing regularly for years, members tend not to RSVP. If there are any questions, feel free to message.

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.

Let’s meet, wander the exhibits and open galleries, and enjoy an evening out in the Franklinton Arts District. (Nearby pay parking is available in the garage on McDowell, right around the corner from One Line Coffee, and, past it along the curb as McDowell dead ends.)
