Hi VIGNERON,
I've tried the query that you provided and it works fine. I tried writing one of my own .
SELECT ?item ?ISIN ?official_name ?official_nameLabel ?official_website WHERE {
OPTIONAL { ?item wdt:P1448 ?official_name. }
OPTIONAL { ?item wdt:P946 ?ISIN. }
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
?item wdt:P31 wd:Q783794.
?item wdt:P856 <https://www.google.com>
}
This doesn't return anything. I'm trying to understand what was wrong here. Why wouldn't it return the details about Google?
