-No. That isn’t how MV work. If you include an MV relation in your query from clause there is no reference or

Thx David
Cool so that is what my understanding was. But that comes back to my main question - the MV is cached data from the
lasttime refresh was run. If I query the MV and the underlying realtime data changes (i.e. from the source tables not
theMV) - should I be getting a replication conflict issue? I would have thought not as the MV data should not have
beenimpacted
