            criteria.setProjection( Projections.projectionList().add(Projections.property("ld")));
            return criteria.list();
        }

Answer 1

Firstly, there is a ';' in the first column name. That might be the reason it is not getting results. Secondly, all projections should be added to the same projection list like below;

public List<abc> Extractingioapublishfor()
        {
            Criteria criteria = session.createCriteria(abc.class);

            criteria.setProjection( Projections.projectionList().add(Projections.property("rId"))
 .add(Projections.property("tId")).add(Projections.property("ld")));
            return criteria.list();
        }
