Lucas_Werkmeister_WMDE added a project: Wikidata-Query-Service.
Lucas_Werkmeister_WMDE added a comment.
Disabling the optimizer works as a workaround:
SELECT distinct ?id ?lang ?n
WHERE {
hint:Query hint:optimizer "None".
{
?id rdfs:label|skos:altLabel "Paris"@en .
BIND("EN" AS ?lang)
}
UNION
{
?id rdfs:label|skos:altLabel "Paris"@eu .
BIND("EU" AS ?lang)
}
?id wikibase:statements ?n .
}
Presumably it’s deciding to find all `wikibase:statements` triples first and
join them against the label/altLabel triples later, which is unwise.
