Detta kriterium fungerar för min MySQL-fråga
@Override
@Transactional
@SuppressWarnings("unchecked")
public List<AttendanceEntry> getAttendanceByDateSearch(String classId, String sectionId, Date date) {
Criteria cr = getSession().createCriteria(AttendanceEntry.class,"attendanceEntry")
.createAlias("attendanceEntry.attendance","attendance")
.setProjection(Projections.projectionList()
.add(Projections.property("rollno"),"rollno")
.add(Projections.property("absent"),"absent")
.add(Projections.property("leave"),"leave")
.add(Projections.property("od"),"od")
.add(Projections.property("absentDate"),"absentDate")

.add(Restrictions.eq("attendance.classYear.id", classId))
.add(Restrictions.eq("attendance.section.id", sectionId))
.add(Restrictions.eq("absentDate", date))
.setResultTransformer(Transformers.aliasToBean(AttendanceEntry.class));
return cr.list();
