Some people say Truncate & Drop are also fullly logging operations but some people are saying these are minimally logged operations. Which is right?

They're fully logged operations.

What people refer to as "Fully Logging" and "Minimally Logged" operations varies a whole lot from person to person (although Books Online is quite explicit in what MS defines as "Minimally Logged"). I really don't like either expression because of the technical semantics involved and the confusion they have caused.

I strongly recommend you read the article that Gail provided a link to because it explains the answer to your very question in the second paragraph. You should read the rest of the article, too.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
