I need some help with the following code. I am using parameterized sparql
string and I want to display combined results of both queries how can I do
that. Any help or suggestion would be truly appreciated.
final static String filename = "/home/samita/turtleContent.ttl";
static Model model= null;
final static String turtleContent = "" +
"@prefix : <http://example.org/> .\n" +
"\n" +
":alice :hasName \"Alice\" .\n" +
":alice :hasAddress \"4222 Clinton Way\" .\n" +
":herman :hasName \"Herman\".\n" +
":herman :hasAddress \"1313 Mockingbird Lane\" .\n" +
":DrWho :hasAddress \"The TARDIS\"" +
"";
// Read the model from the turtle content
final static Model model = ModelFactory.createDefaultModel()
// .read( new ByteArrayInputStream( turtleContent.getBytes()), null,
"TURTLE" );
final static String findAlice = "prefix : <http://example.org/>" +
"select ?alice where {" +
"?alice :hasName \"Alice\" }" ;
final static String findAliceAddress = "prefix : <http://example.org/>" +
"select ?address where {" +
" ?alice :hasAddress ?address }";
public static void useParameterizedSPARQLString() {
System.out.println( "== useParameterizedSPARQLString ==" );
// execute the query that finds a (single) binding for ?alice. Then
create
// a query solution map containing those results.
final ResultSet aliceResults = QueryExecutionFactory.create( findAlice,
model ).execSelect();
final QuerySolutionMap map = new QuerySolutionMap();
map.addAll( aliceResults.next() );
// Create a ParameterizedSparqlString from the findAliceAddress query
string (if this
// approach were taken, findAliceAddress could actually *be* a
Param.SparqlString, of
// course).
final ParameterizedSparqlString pss = new ParameterizedSparqlString(
findAliceAddress );
System.out.println( pss.toString() );
pss.setParams( map );
System.out.println( pss.toString() );
// execute the query and show the results
ResultSetFormatter.out( QueryExecutionFactory.create( pss.toString(),
model ).execSelect() );
}
The results I get is:
----------------------
| address |
======================
| "4222 Clinton Way" |
----------------------
Is there any way to display the variable ?alice also
Like
alice address
http://example.org/alice "4222 Clinton Way"<http://example.org/alice>
