Using Hibernate's Criteria and Projections to Select Multiple Distinct Columns

Question

Using Hibernate\'s Criteria, I want to execute the equivalent of:

select distinct uspscity, state from citycomplete where USPSCITY = \'HOUSTON\'

Answer 1

ProjectionList projList = Projections.projectionList();
projList.add(Projections.property("id.state"));
projList.add(Projections.property("id.uspsCity"));
criteria.setProjection(Projections.distinct(projList));
