Actually, I figured out what you're trying to do here. My guess is that the
COMMENT does not understand sequences like %m/%d/%Y. Try the following:
instead of saying cur_date = '%m/%d/%Y %H\:%M\:%S', declare cur_date as a
datetime object, then use an appropriate string representation of it to
concatenate with COMMENT.
Hope it helps.
