Using Jena 2.11.0 and the jena providers off the Virtuoso web site, I've
executed the following query:
VirtGraph set = new VirtGraph ("jdbc:virtuoso://localhost:1111", "dba",
"dba");
Query sparql = QueryFactory.create("SELECT * WHERE { GRAPH ?graph { ?s
?p ?o } . values ?graph {<http://ips.ebremer.com>}} limit 1");
VirtuosoQueryExecution vqe = VirtuosoQueryExecutionFactory.create
(sparql, set);
ResultSet results = vqe.execSelect();
results.hasNext() at the end of this code results in false. However,
there are numerous solutions. If I set limit to 2, I will get one
result. If I set it to 11, I will get 10 results, etc... The same
query, directly against the sparql endpoint works fine. The solutions
are all off by one.
