Hibernate criteria api 'Select in'

Question

is it possible to create a \'select in\'-query with the hibernate critiria api ?

Example : I have two tables in a 1:n relation, company and department

Answer 1

You can use for this DetachedCriteria

DetachedCriteria subCriteria= DetachedCriteria.forClass(Departament.class);
     subCriteria.add(Property.forName("departmentname ").eq("HR"));
     subCriteria.add(Property.forName("location ").eq("xyz"));
     subCriteria.setProjection(Projections.property("company_id "));

DetachedCriteria criteria = DetachedCriteria.forClass(Company.class);
     criteria.add(Property.forName("id").in(subCriteria));
