Hibernate学习31 -- Hibernate查询语言（HQL）5 -- 直接使用sql进行查询

hibernate也支持直接使用sql进行查询，例子代码如下：

/**  * 原生sql测试  */ public class SqlQueryTest extends TestCase {       public void testQuery1() {        Session session = null;        try {            session = HibernateUtils.getSession();            session.beginTransaction();                   List students = session.createSQLQuery ("select * from t_student").list();            for (Iterator iter=students.iterator(); iter.hasNext();) {               Object[] obj = (Object[])iter.next();               System.out.println(obj[0] + "," + obj[1]);            }            session.getTransaction().commit();        }catch(Exception e) {            e.printStackTrace();            session.getTransaction().rollback();        }finally {            HibernateUtils.closeSession(session);        }     } }
