I don't quite understand. You mention "fast snapshots". There's no
such thing as a "fast snapshot", only fast refresh, which applies
changes from the snapshot log on the master table. If you were to
truncate the underlying snapshot table and then attempt a fast refresh,
the refresh would fail.
I think you want to do complete refreshes of your snapshots. They
start out by truncating the snapshot table.
