A comedy show with headliner Bianca Lala from Romania 🇷🇴 , featuring some of the funniest international acts in Luxembourg : Jerry,🇹🇷 Keli,🇦🇱 and hosted by Ken Park🇱🇺. **About the Artists:🎙️** **BIANCA LALA:** She does comedy because she’s Gen Z and believes in healing - but ironically. She’s also Romanian, which means she’s chasing her dreams, but like, with low expectations. She used to work in sales until she discovered her true passion: not making money. If you’ve ever cried on a Flixbus, called your mom just to fight, or tried to fix a guy whose whole personality was a Japanese tattoo and a really bad impression of Matthew McConaughey - congrats, you have something in common with her. She’s performed in 38 cities and 19 countries (one of which was Slovakia, so it doesn't count) and has had airport panic attacks in 5 of those. She currently has the most viewed set on Red Mic’s YouTube channel (“What Doesn’t Kill You Makes You Kinky”) - 239k views and counting. As the co-founder of Unhinged Theatre, she also works behind the scenes, writing scripts and crafting chaotic yet entertaining plotlines. **JERRY:** Jerry is a Turkish comic and one of Luxembourg’s rising stars, chronicling the chaos of singlehood in her thirties, where her relationship status refreshes every 24 to 48 hours. Her comedy dives into expat struggles, working life, and the absurdities of trying to settle down abroad. **KELi:** Raised in Greece, Albanian by birth, princess by choice, resides currently in Luxembourg after several failed attempts at staying in one country. His comedy is observational and story-led, built around social and cultural commentary and that complaining is his preferred way of understanding the world. An archivist/librarian, cat enthusiast and metalhead who enjoys his boring job and wants to bring attention to immigrant stories and everyday cultural absurdities. **MC** **KEN PARK:** Once a skater boy, now a domesticated husband and proud plant addict, Ken brings easygoing stories and sharp observations to the stage. He somehow finds a way to click with every crowd, no matter the clique. Always welcomed everywhere, he puts the 'in' in inclusive. **Where**: ROCAS, 33 Rue des Capucins, 1313 Ville-Haute, Luxembourg **When:** 7th of March I 8PM **Tickets:🎟️** https://www.eventbrite.com/e/balkan-baddie-and-friends-a-standup-comedy-show-tickets-1982567534866?aff=oddtdtcreator Come and enjoy some drinks before the show!

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.
