nice! pretty painless, too. do you mind spending a
minute explaining the mechanics? obviously, the
format does a little more than just input the values,
otherwise it would be just like the other format.
if bad data is submitted, is there something going on
"behind the scenes" to scrub the bad data and cause
the query to fail instead of run with the bad data?
how does the the system know the data is bad data?
this is new to me, but very interesting.
