Hibernate Native Entity Query

This section contains detail about Hibernate Native Entity Query with example code.

Using HQL or criteria query in Hibernate, you can execute nearly any type of SQL query. Even so some developer complaint about slowness of statement generated by Hibernate and they opt to generate their own SQL statement. These developer generated query is known as Hibernate Native SQL Query.

In Hibernate Native Entity Query, each row of ResultSet converts into a POJO object. Through addEntity( ) method selected data will map automatically to the passed class to the addEntity( ) method.


In the below example. we are fetching all the values from worker table using Hibernate native entity query.

The project hierarchy is given below :

The query for creating table worker is given below :

CREATE TABLE `worker` ( 
`worker_id` bigint(10) NOT NULL auto_increment, 
`firstname` varchar(50) default NULL, 
`lastname` varchar(50) default NULL, 
`birth_date` date NOT NULL, 
`cell_phone` varchar(15) NOT NULL, 
PRIMARY KEY (`worker_id`)

Session session = sf.openSession();
try {
String sql = "SELECT * FROM worker";
SQLQuery query = session.createSQLQuery(sql);
List workers = query.list();

for (Iterator iterator = workers.iterator(); iterator.hasNext();) {
Worker worker = (Worker) iterator.next();
System.out.println("Worker Id:" + worker.getWorkerId());
System.out.println("Worker Name:" + worker.getFirstname());
System.out.println("Worker Birth Date:" + worker.getBirthDate());
System.out.println("Worker CellPhone No."+ worker.getCellphone());
} catch (HibernateException e) {
if (session.getTransaction() != null)
} finally {


After execution, you will get the following result on console :
