Hibernate Criteria Expression (gt)

In this section, you will learn to use the "gt" method. This is one of the most important  method that is used to apply a "greater than" constraint to the named property
Expressions: The Hibernate Criteria API supports a rich set of comparison operators. Some standard SQL operators are =, <, ?, >, ?. That supports gt() method in Expression class.
In this tutorial, "gt" is used with the Long object (ID). It takes two parameters e.g. ge("property_name",Object val).
Table Name: insurance

ID	insurance_name	invested_amount	investement_date
2	Life Insurance	25000	0000-00-00 00:00:00
1	Givan Dhara	20000	2007-07-30 17:29:05
3	Life Insurance	500	2005-10-15 00:00:00
4	Car Insurance	2500	2005-01-01 00:00:00
5	Dental Insurance	500	2004-01-01 00:00:00
6	Life Insurance	900	2003-01-01 00:00:00
7	Travel Insurance	2000	2005-02-02 00:00:00

Here is the code of the class using "gt" Expression :

package roseindia.tutorial.hibernate; import java.util.Iterator; import java.util.List; import org.hibernate.Criteria; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; import org.hibernate.criterion.Expression; public class HibernateCriteriaQueryExpressionGt {   /**  * @param args  */   public static void main(String[] args) {   // TODO Auto-generated method stub   Session sess = null;   try {   SessionFactory fact = new  Configuration().configure().buildSessionFactory();   sess = fact.openSession();   Criteria crit = sess.createCriteria(Insurance.class);   crit.add(Expression.gt ("lngInsuranceId",new Long(3)));   List list = crit.list();   for (Iterator it = list.iterator();it.hasNext();){   Insurance ins =  (Insurance)it.next();   System.out.println(" Insurance Id: "  + ins.getLngInsuranceId());   System.out.println(" Insurance Name: " + ins.getInsuranceName());   System.out.println(" Insurance Amount: " + ins.getInvestementAmount());   System.out.println(" Investement Date: " + ins.getInvestementDate());   }   sess.close();   }   catch(Exception e){   System.out.println(e.getMessage());   }   } }

Output:
