This sounds a really simplistic question, but based on what you've said, it should just be:
update xys set submitdate=NULL where id in ('1','2'.........'100')
I feel I must be missing something as surely if you know how to set the rows to one value, you know how to set it to another...
If I could find an emoticon for perplexed, it would be right here!
