Now we will look at how to limit the number of rows using hibernate.
Here's a scenario to easily understand what we are about to do.
Let's consider that we have four rows in an employee table, and a SELECT * FROM employee SQL query returns all four records. However, if we want only the second and third records, we can use the SELECT * FROM employee LIMIT 1, 2 SQL statement.
Let's take a look at how to achieve such a condition in hibernate:
Enter the following code to paginate using a criteria:
SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
Session session = sessionFactory.openSession();
Criteria criteria = session.createCriteria(Employee.class);
criteria.setFirstResult(1); // represent LIMIT 1,* in MySQL
criteria.setMaxResults(2);// represent LIMIT *,2 in MySQL
List<Employee> employees = criteria.list();
for (Employee employee : employees) {
System.out.println(employee.toString());
}
session.close();
HibernateUtil.shutdown...
