How to query Wikidata using SPARQL for a specific property?

Question

I'm using the Wikidata Query Service to try and get all instances within Wikidata that contain a UMLS CUI (Property P2892).

I've tried doing

SELECT ?item
WHERE
{
  ?item wd:P2892.
}

But am getting the error Query is malformed: Encountered " "." ". "" at line 3, column 17.

How can I fix this error?

SPARQL expects **triple** patterns, you have just a **tuple**. It should be `SELECT ?item WHERE { ?item wd:P2892 ?cui . }` — UninformedUser, Jan 11 '21 at 07:41
And also `wdt:P`, not `wd:P` in predicate position, see https://m.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format. — Stanislav Kralin, Jan 11 '21 at 09:57
true, should be `SELECT ?item WHERE { ?item wdt:P2892 ?cui. }` — UninformedUser, Jan 11 '21 at 10:39
