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).

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());
  }
  }
}
