I have mapped a table with a lot of colums to an Object. For use in statistics i invented a "LightObject" version, with only a few colums and cached it read-only.
Then i tried following code:
Code:
List result = session.find( "select o from LightObject as o left join o.entries as oe WHERE oe.someInformation is not null" );
for( Iterator it = result.iterator(); it.hasNext(); )
{
LightObject lo = (LightObject it.next();
Object ob = ObjectDAO.getInstance().load( lo.getId() );
ob.setSomeFlag( 1 );
ObjectDAO.getInstance().saveOrUpdate( order );
}
