since when have you ever "respectfully" disagreed with me? :)

you are correct, semantically I should have said he cannot rollback the truncate and because he has no backups, he cannot recover from the action either.

of course, your recovery does depend on knowing exactly when the truncate took place. Otherwise you may have to do multiple recoveries until you find the correct time.

the bottom line is, under the given conditions, the action cannot be reversed and the data lost cannot be restored. The only option is to recreate.
