You can specify a batchsize for a bulk load, and SQL then commits every time after that many rows are loaded (obviously you definitely want to specify a batchsize for...

As for the restore, it's very easy to create a script to have SQL restore the last backup of a db.

Maybe, then you could also do this:

a.* -- to save time, should define all columns you want to return
from
dbo.Appointments a

I strongly suspect you will want to see more details on the last appointment than just the date:
SELECT
CustomerId, AppointmentDate, ...

but that does not mean that someone else didn't change something
As Lynn has stated, that can happen even without any change being made to anything.
SQL only provides ORDERing if you...

Yes, your queries will be vastly faster if you cluster on add datetime rather than identity. Hopefully your queries are then typically like this:
SELECT
SUM(...) AS...

An occassional highly unusual exception doesn't validate the horrible idea in general of identity as the default for a clus key.

True, there could be special situations.
you could potentially have a very large and active table that is in a database mirrored over a slow wan connection.
If you're trying to mirror...

Other than logging-type tables, where the clus key value is essentially irrelevant, I can't imagine any case where identity would be the proper clus key on business data.
Sure, for some...

There are vastly better ways to stress that in general a table needs a clustered key than to have the damaging and false notion that it should be an identity...

While I may agree, I have to play devils advocate, why not cluster on the identity column?
Because the overwhelming majority of queries will specify the datetime.

Create a logon trigger, and capture everything you can -- app_name, host_id, host_name (most people don't bother to fake this) and original_login (just in case).
You could of course then also...
