Solution

Sure, here are the basic operations in Hibernate:

  1. Insert Operation: This operation is used to add new records into the database. In Hibernate, you can use the save() or persist() method of the Session interface to store an object in the database.
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
Employee emp = new Employee();
emp.setName("John");
emp.setSalary(1000);
session.save(emp);
tx.commit();
session.close();
  1. Delete Operation: This operation is used to remove records from the database. In Hibernate, you can use the delete() method of the Session interface to remove an object from the database.
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
Employee emp = session.get(Employee.class, 1);
session.delete(emp);
tx.commit();
session.close();
  1. Update Operation: This operation is used to modify existing records in the database. In Hibernate, you can use the update() or merge() method of the Session interface to update an object in the database.
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
Employee emp = session.get(Employee.class, 1);
emp.setSalary(2000);
session.update(emp);
tx.commit();
session.close();
  1. Search Operation: This operation is used to retrieve records from the database. In Hibernate, you can use the get() or load() method of the Session interface to fetch an object from the database.
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
Employee emp = session.get(Employee.class, 1);
System.out.println(emp.getName());
tx.commit();
session.close();

Remember to replace Employee with your actual entity class and adjust the properties accordingly.
