Example 1 with DebugTdbConnection

use of org.apache.jena.jdbc.tdb.connections.DebugTdbConnection in project jena by apache.

     */
@Test
public void results_ask_true() throws SQLException {
    Dataset ds = createDataset(tempDir.getRoot().getAbsolutePath());

        Statement stmt = connection.createStatement(TYPE_FORWARD_ONLY, CONCUR_READ_ONLY);
        ResultSet rset = stmt.executeQuery("ASK { }");
        assertNotNull(rset);
        assertFalse(rset.isClosed());
        assertTrue(rset.isBeforeFirst());
        // Try to move to the result row
        assertTrue(rset.next());
        // Check the boolean return value
        assertTrue(rset.getBoolean(COLUMN_LABEL_ASK));
        // Check no further rows
        assertFalse(rset.next());
        assertTrue(rset.isAfterLast());
        // Close and clean up
