@Test
public void testUpdate() {
    String sql = "UPDATE TABLE1 SET NAME = ? WHERE ID = ?";

    Map<Integer, ParameterContext> currentParameter = new HashMap<Integer, ParameterContext>();
    ParameterContext p1 = new ParameterContext(ParameterMethod.setObject1, new Object[] { 2 });
    currentParameter.put(1, p1);

    Parameters parameterSettings = new Parameters();
    parameterSettings.getCurrentParameter().put(1,
        new ParameterContext(ParameterMethod.setObject1, new Object[] { 1, "hello1" }));
    parameterSettings.getCurrentParameter().put(2,
        new ParameterContext(ParameterMethod.setObject1, new Object[] { 2, 1 }));
