Update only selected columns

I''m working on an "update your profile" page.  One of the
fields is
the user''s password.  I have a couple of validation rules set up in
the user model regarding the password''s minimum and maximum length and
it not being blank, etc.  They work great.  However, is there a way to
turn them off and not update that column if the user does not enter
anything in that field?
