Sorry I think I did not made myself very clear.

Actually I want to have the data in Oracle rollback segment(not the actual table). So that I can fire some SQL to do validations etc. So that if the validation passes I will issue a commit or just issue a rollback command.

Oracle D2K Forms POST does that automatically. As there is nothing .Net or ODP.Net to do the same. I am trying to achieve that programatically.
