Airports (again :), and with that query, you'll see that when there is multiples statements for same month+year : they are added instead of being sampled. I wonder if I change the (SUM(?numberperperiod) AS ?number) to (MAX(?numberperperiod) AS ?number) would have any drawbacks/side effects. (Q854130)Cape Town International Airport Hello, sorry to bother you again, hope you'll get a better year 2021 than 2020! I'm having a difficulty when airport data has multiples monthly source. Eg with ]reply[21:46, 8 January 2021 (UTC) 💛●✒️●💬 BouzinacAny thoughts ?
