我已经弄清楚如何对数据库进行更改,这里有一些代码来演示:
I have figured out how to make changes to the database here is some code to demonstrate:
try {
/** define the session and begin it **/
hbsession = HibernateUtil.getSessionFactory().getCurrentSession();
hbsession.beginTransaction();
/** table is the name of the Bean class linked to the corresponding SQL table **/
String query = "UPDATE table SET name = " + textfield.getValue();
/** Run the string as an SQL query **/
Query q = hbsession.createQuery(query);
q.executeUpdate(); /** This command saves changes or deletes a entry in table **/
hbsession.getTransaction().commit();
} catch (RuntimeException rex) {
hbsession.getTransaction().rollback();
throw rex;
}
