Example 1 with UpdateExecution

use of org.apache.jena.update.UpdateExecution in project jena by apache.

the class AbstractTestDatasetWithTextIndexBase method doUpdate.

Example 2 with UpdateExecution

use of org.apache.jena.update.UpdateExecution in project jena by apache.

the class TestParameterizedSparqlString method test_param_string_bnode_3.

@Test
public void test_param_string_bnode_3() {
    // Test case related to treatment of blank nodes when injecting into
    // SPARQL updates using _: syntax
    Model model = ModelFactory.createDefaultModel();

    Assert.assertEquals(1, model.size());
    Dataset ds = DatasetFactory.wrap(model);
    // Use a parameterized query to check the data can be found
    ParameterizedSparqlString pq = new ParameterizedSparqlString();
    pq.setCommandText("SELECT * WHERE { ?s ?p ?o }");
    pq.setIri("s", "_:" + bnode.getId());
    Query q = pq.asQuery();
    try (QueryExecution qe = QueryExecutionFactory.create(q, ds)) {
        ResultSet rset = qe.execSelect();
        Assert.assertEquals(1, ResultSetFormatter.consume(rset));
    }
    // Use a parameterized update to modify the data
    ParameterizedSparqlString s = new ParameterizedSparqlString();
    s.setCommandText("INSERT { ?o ?p ?s } WHERE { ?s ?p ?o }");
    s.setIri("s", "_:" + bnode.getId());
    UpdateRequest query = s.asUpdate();
    UpdateExecution proc = UpdateExecutionFactory.create(query, ds);
    proc.execute();
    // This should be true because this was present in the intial model set
    // up
    Assert.assertEquals(1, model.listStatements(bnode, null, (RDFNode) null).toList().size());
    // This should return 0 because the INSERT should result in a new blank
    // node being created rather than the existing one being reused becaue
    // of the semantics of blank nodes usage in templates
    Assert.assertEquals(0, model.listStatements(null, null, bnode).toList().size());
}
