Free, registration-only fringe event run by Oracle's MySQL Community Team in Brussels on the Thursday/Friday before FOSDEM, at the ICAB Incubator (Etterbeek). Started in 2017 as the one-day 'pre-FOSDEM MySQL Day' (lefred's posts say 'since 2017' and, once, 'since 2018'); the 2019 edition was the third. Two days from 2020 ('pre-FOSDEM MySQL Days'); renamed 'MySQL Belgian Days' in 2024 when FOSDEM rejected the MySQL devroom, then 'preFOSDEM MySQL Belgian Days' (2025-2026); the 2027 call for papers uses 'MySQL Belgian Days 2027'. No editions in 2021-2022 (FOSDEM was online). Typically day 1 is community/ecosystem speakers and day 2 Oracle MySQL engineers, ending with the MySQL Rockstar awards; the Belgian 'Party Squad' community dinner (separately ticketed) follows on Friday night. 2017-2018 editions are before this database's scope. No sponsor lists are published (Oracle hosts; logos on mysqlandfriends.eu relate to the community dinner and devroom, not the Belgian Days). Social accounts are Oracle MySQL's (the event has none of its own); Mastodon is the MySQL Community account linked from mysqlandfriends.eu.
