The Hibernate Query Language, (HQL) similar to SQL designed, having some features of Object oriented concepts. It provides the bridge between your database to your application. Here is one example of case insensitive search.

package net.roseindia.main;

import java.util.*;
import net.roseindia.table.Employee;
import net.roseindia.util.ConnectionUtil;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;

public class CaseInsensitiveHQL {
    public static void main(String[] args) {
        SessionFactory sessionFactory = ConnectionUtil.getSessionFactory();
        Session session = sessionFactory.openSession();
        String hql="SELECT emp from Employee emp WHERE emp.name='Ron'";
        Query query=session.createQuery(hql);
        Iterator it=query.iterate();
        while ( it.hasNext()) {
            Employee employee = (Employee) it.next();
            System.out.println(employee.getName());
            System.out.println("Salary : "+employee.getSalary());
        }
        session.close();
    }
}

Description: Here we are printing name and salary of employee whose name matches to ?Ron? .HQL looks like SQL.Its query is case-insensitive expect we are using the java class and properties.
