Execute native sql with hibernate

I’m using hibernate 4.2.6 and PostgreSQL 9.1 I’ve been trying to execute sql query with hibernate. I’ve written:

Session session = Hibernate.util.HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
String sql = String.format("INSERT INTO products (name,cost) VALUES('%s',%s);", product.getName(), product.getCost());
createSQLQuery(sql);//has no effect. Query doesn't execute.
session.getTransaction().commit();
session.close();

This query does not executed in DB. But if I write

String sql = String.format("INSERT INTO products (name,cost) VALUES('%s',%s);", product.getName(), product.getCost());
Properties connectionProps = new Properties();
connectionProps.put("user", "postgres");
connectionProps.put("password", "123");
Connection conn = DriverManager.getConnection("jdbc:postgresql://localhost:5432/solid",connectionProps);
conn.createStatement().execute(sql);

corresponding row will add to table. Why hibernate doesn’t work, but native query wth JDBC works?

This should help you.

Session session = Hibernate.util.HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
String sql = String.format("INSERT INTO products (name,cost) VALUES('%s',%s);",product.getName(), product.getCost());
session.createSQLQuery(sql).executeUpdate();
session.getTransaction().commit();
session.close();
