DB_DataObject

I'm having a problem using it to get all the records from the table. I've got a class, Users, that extends DB_DataObject (generated using createTables.php). If I just want to get a subset, this works perfectly fine: $users = new Users(); $users->country = 'USA'; $users->find(); Ok, so now I just want to get all the users. So after reading the DB_Object documentation (and the source code), the closest I was able to determine how to do this is as follows: $users = new Users() $users->selectAdd('*') //$users->find(); // Actually, I'm not even sure this is needed So the only change in my code is to use selectAdd() instead. If I make that change, I get an error message saying: "DB_DataObject Error: No database name / dsn found anywhere" Why am I getting that? Everything worked fine enough for the first example. Also, am I doing the right thing to get all the records in the table? thnx, Chris
