Hi Rob Broadhead.
I use Mysql witch allow to change PK.
I don't get a SQL exception. Torqe do a "select from server where server.serveradress='newServerAdress'"
when I call server.setServeradress("newServerAdress").
Of corse, such server is not in Database so Torque do nothing.
In my code I don't do nothing.
I fetch a server object with server.getServeradress() -> 'oldServerAdress'.
And this object I would like to change in 'server.setServeradress("newServerAdress")'.



In sql I would write this query:
update server set serveradress='newServerAdress' where serveradress='oldServerAdress'

Most databases don't allow the PK to be changed. You should be getting a SQL exception along those lines. Also, in your example you iterate through the list of servers and don't do anything other than iterate so I may not be understanding what you are attempting to do.

Hi!
I have the tables 'server' and 'file'.
How can I update the 'server.serveradress' (PK) and 'file.serverAdress' (FK) with Torque?
The attribute 'file.serverAdress' have the flag onUpdate="cascade".


I try folowing:
   Criteria crit = new Criteria();
   crit.add(ServerPeer.SERVERADRESS, "oldServerAdress");
   List v = ServerPeer.doSelect(crit)

   Iterator iteratorServer = v.iterator();
   Server server;
   if(iteratorServer.hasNext()){
           server = (Server) iteratorServer.next();
   }

server.setServeradress("newServerAdress");

   ServerPeer.doUpdate(server);    // don't work
   server.save();                             // don't work, too

Thanks for your attention

Greetings Tomek
