*The following query works * :
"SELECT ?student ?highScore " +
" WHERE {" + " {"+ "select (max(?score) as ?highScore)"
+ " { ?student dd:Englishscore ?score" +
" }" +
" } " +
"?student dd:Englishscore ?highScore" +
"}";
Query query2 = QueryFactory.create(queryString2);
QueryExecution qexec = QueryExecutionFactory.create(query2, model2) ;
ResultSet results2 = qexec.execSelect() ;
Literal r= results2.next().get("highScore").asLiteral();
String ss= r.getLexicalForm();
JOptionPane.showMessageDialog(null,"High score of Physics is"+s + "by
Student");
This query now works but when I include also the student name, it gives me
exception again.
* Resource r2= results2.next().get("student").asResource();*
* String s=r2.toString();*
