If it is what I think it is then it is probably widely known, just not
to me :-)
I would like to get certain, though, because I do have some respect
for things happening and looking strange (might always be an early
sign of some corrution) so here goes:
Do new columns - without having inserted anything to them and without
any default value nor being part of any constraint - not make it into
the next backup?
I have the - for me - strange situation that I added 2 columns to a
production database, left them completely NULLed, created backup,
restored to local backup-database;
the local backup then contained all the latest records of the tables
in question, but not the new columns.
I tried several times, no changes, then I added a single value in each
of the columns and they got restored to the local test database.
Thanks in advance for confirmations/warnings!
