Examples of org.openrdf.repository.RepositoryConnection.prepareTupleQuery()

org.openrdf.repository.RepositoryConnection.prepareTupleQuery()
Prepares a query that produces sets of value tuples. In case the query contains relative URIs that need to be resolved against an external base URI, one should use {@link #prepareTupleQuery(QueryLanguage,String,String)} instead. @param ql The query language in which the query is formulated. @param query The query string. @throws IllegalArgumentException If the supplied query is not a tuple query. @throws MalformedQueryException If the supplied query is malformed. @throws UnsupportedQueryLanguageException If the supplied query language is not supported.

        String query3 = "PREFIX : <http://ripple.fortytwo.net/code/2011/06/rippleSailExamples#>\n" +
                "SELECT ?name WHERE {" +
                "    () :embarcadero/:parent-place*/s:name ?name ." +
                "}";


        TupleQueryResult r = rc.prepareTupleQuery(QueryLanguage.SPARQL, query2).evaluate();
        while (r.hasNext()) {
            System.out.println("result: " + r.next());
        }


        rc.close();
