How to query specific entities from Wikidata by ID using a SPARQL query? - sparql

Question

I need a SPARQL query returning a specific Wikidata ID or a list of IDs. In real life such query is useless but I need it for testing purposes.
The easiest variant I could come up with was:
SELECT DISTINCT ?s
WHERE
{
?s ?p ?o
FILTER (?s = wd:Q151345).
}
I have to use DISTINCT because ?s ?p ?o matches every triple within Q151345, if I omit it it output the item as many times as many property-value pairs it has.
Is there any easier way?

Answer 1

With the keyword VALUES, it's possible to use multiple instances.
PREFIX bd: <http://www.bigdata.com/rdf#>
PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX wikibase: <http://wikiba.se/ontology#>
SELECT ?s
WHERE
{
VALUES ?s { wd:Q151345 wd:Q2996394 }
?s ?p ?o
}
LIMIT 10

#greatvovan You can try
PREFIX bd: <http://www.bigdata.com/rdf#>
PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX wikibase: <http://wikiba.se/ontology#>
SELECT DISTINCT ?s WHERE {
SELECT ?s WHERE
{
VALUES ?s { wd:Q151345 wd:Q2996394 }
?s ?p ?o
}
}
