If with the TIBOTable and TIBOQuery you are already using persistent
fields, then you wouldn't be able to see the new fields that would be
added in runtime. It's just how persistent fields work, if the field
is not added to the persistent fields in design-time, then you can't
access the field in runtime, even if it's part of the table or the
query's result set. If you want to be able to add fields to the
result set in run-time, then don't use persistent fields in
