I'm new here and maybe I'm oversimplifying, but isn't wrapping a
truncate up in a transaction just a bit of SQL "sleight of hand"?

Would one be able to rollback a truncate in a session with
implicit_transactions set?

Truncate is not supposed to be able to be rolled back, as it deallocates
the data files and makes their extents available for writing over. The
actual deallocation is logged in the transaction log however, but
technically TRUNCATE statements are not available for rollback. However
if you put the truncate statement within a BEGIN TRAN - (ROLLBACK TRAN)
COMMIT TRAN block, then of course that sessions activity is capable of
rollback. However, if you FUBAR by the use of TRUNCATE and have a
backup.... Is this a trick question?
