The best thing is to fix your loop logic.  Usually it's not hard to emit
a comma only if one is needed.

If you're intent on using a broken loop, you could do "foo = foo" where
foo is any table column you didn't yet assign to.  Consider though the
corner case where you've already assigned all the columns.  Best bet
is to fix your loop...
