	Criteria criteria = getCurrentSession().createCriteria(LabOrder.class);
criteria.add(Restrictions.sqlRestriction("YEAR(createdDate)="
+ labOrderConditions.getYear()));
ProjectionList projectionList = Projections.projectionList();
projectionList.add(Projections.sqlGroupProjection(
"MONTHNAME(createdDate) as orderMonthName",
"MONTHNAME(createdDate)", new String[] { "orderMonthName" },
new Type[] { StandardBasicTypes.STRING }));
projectionList.add(Projections.sqlGroupProjection(
"Month(createdDate) as orderMonthNo", "Month(createdDate)",
new String[] { "orderMonthNo" },
new Type[] { StandardBasicTypes.INTEGER }));
projectionList.add(Projections.rowCount());
criteria.setProjection(projectionList);
criteria.addOrder(org.hibernate.criterion.Order.asc("createdDate"));
return criteria.list();
