NativeCriteria nc = new NativeCriteria(new JpaQueryProvider(entityManager), "address", "a")

      .setProjection(NativeExps.projection().addProjection("a.city"))                       

      .add(NativeExps.isNull("a.zip_code"));                                                

      .setOrder(NativeExps.order().add("a.city", OrderType.ASC));

// dynamic where part

if (StringUtils.isNotEmpty(city)) {

    nc.add(NativeExps.eq("a.city", city))

}            

      

// get the results

CriteriaResult res = c.criteriaResult();                                                    

List cityNames = new ArrayList<>();

while (res.next()) {                                                                        

   resp.add(res.getString("a.city"));
