Updating the Database Table


Next, we will update table values with the Hibernate Java application. Create a query to select data, which is to be modified, from the table

String hqlQuery="from Catalog";

Obtain a Session object from the SessionObject.

Session sess = sessionFactory.openSession();

Obtain a Transaction object from the Session object.

Transaction tx = sess.beginTransaction();

Create a Query object from the HQL query using the createQuery() method of the Session object. Obtain a List result set with the list() method. Obtain the JavaBean object to be modified.

List list = query.list();
Catalog catalog = (Catalog) list.get(0);

catalog.setPublisher("Oracle Magazine");

Transaction tx = sess.beginTransaction();

Update the database table with the saveOrUpdate() method of the Session object...
