Actually I'm unable to understand the comments and answers properly. Problem is with the word "CLOBBER".....Same here but after checking this http://en.wikipedia.org/wiki/Clobbering, it kind of eased the question to understand.
I've never seen this definition of Clobbering before - learn something new every day!
Luckily I know the behaviour of SQL in this scenario & got it right 🙂
Funny thing, this English language of ours... I didn't realize till today that "clobber" was considered slang. Here we have it in its American usage. The basic meaning is to hit something very hard, or hit person so hard they're knocked out, as in "Muhammed Ali clobbered Joe Frazier." Thus the metaphorical meaning as used in this QOD of destroying the target datum.
