Annual Microsoft data platform conference in Wrocław, Poland, organized since 2009 by Data Community Poland (formerly PLSSUG); bills itself as the largest such conference in Central and Eastern Europe. Three days in May at Hala Stulecia (Centennial Hall): a day of paid full-day workshops (pre-cons) followed by a two-day conference, with Polish and English sessions. Hybrid (onsite + online tickets) since 2022. 2019 was in person (13-15 May). SQLDay 2020 was first planned for 11-13 May 2020, then postponed to 30 Nov-2 Dec 2020 and held online only; SQLDay 2021 (10-12 May 2021) was also online only; neither is recorded (online-only events are out of scope). 2027 is announced for 10-12 May 2027. Since 2024 the organizer also runs SQLDay Lite, a smaller two-day autumn event (workshop day + one conference day, ~25 sessions) in a different city each year (Bydgoszcz 2024, Bielsko-Biała 2025, Gdańsk 2026), recorded as editions with id_suffix `lite`. Social accounts: Twitter/Facebook/Instagram are the conference's own; LinkedIn is the organizer's. Sessionize CfP pages: sessionize.com/sqlday-<year> and sessionize.com/sqlday-lite-<year>.
