Hi,
I need help using XSD date/time functions, I tried versions 4.2.0 and 4.7.0 and
both don't seem to work.
Considering this Java code:
Dataset kb = DatasetFactory.createGeneral();
Query q = QueryFactory.create(q);
result = QueryExecutionFactory.create(q, kb).execSelect();
The following throws an NPE (no results)
String q = "\n" +
"PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>" +
"SELECT ?date WHERE { BIND(xsd:dateTime (1649185973) AS ?date ) }";
...
System.err.println(result.next().get("date").toString());
While the cast to int works fine:
String q = "\n" +
"PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>" +
"SELECT ?date WHERE { BIND(xsd:int (1649185973) AS ?date ) }";
System.err.println(executeARQ(q).next().get("date").toString());
1649185973^^http://www.w3.org/2001/XMLSchema#int
Am I missing anything?
Best,
Enrico
