Two more or less political answers:
- In Designer 6i you can create domains which will be translated to native datatypes and synnched. As using Designer you should never ever create a table manually, in theory this is a viable solution for your need - On database level this is not (yet?) possible, presumably because it has been implemented in Designer and Oracle feels you should use (their) Case product, and not hack away and create tables on the fly (I have the feeling that is still the most common development method in the world, and I have seen often enough what comes from it: overtime, lack of sleep, in short a nightmare)
