Hibernate provides facility to update the existing record. Here is an example

Example-

package net.roseindia.main;

import net.roseindia.table.Employee;
import net.roseindia.util.HibernateUtil;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;

public class HibernateUpdate{
    public static void main(String [] args){
        SessionFactory sessionFactory=HibernateUtil.getSessionFactory();
        Session session=sessionFactory.openSession();
        Transaction transaction=session.beginTransaction();
        Employee employee=(Employee) session.get(Employee.class, new Integer(1));
        employee.setName("Mandy");
        employee.setSalary(20000);
        session.update(employee);
        transaction.commit();
        session.close();
        System.out.println("Updated");
    }
}

Output:

Hibernate: select employee0_.emp_id as emp1_0_0_, employee0_.date_of_join as date2_0_0_, employee0_.name as name0_0_, employee0_.salary as salary0_0_ from employee employee0_ where employee0_.emp_id=?
Updated

Description: this example updates the record of employee whose id is 1.We can do this by setting the value and calling the update method.

session.update(employee);
