Help needed with blob fields OldValue and NewValue -
On Delphi XE I'm using OldValue and NewValue from TpFIBDataSet(but it can be applied to any TDataSet descendent) in order to verify if different fields have changed. My questions is how can I retrieve these 2 values for the blob fields as TMemoryStreams? I've made some research, but I found nothing.
Any idea on this?
