Old school method:
<input type="text" name="new_foo" value="[value_from_db]">
<input type="hidden" name="original_foo" value="[value_from_db]">

User enters a new value in the field new_foo and submits the form.

if(action_param('new_foo') != action_param('original_foo'));
// update column
/if;

Is there a smarter, knoppier way of doing this, either for a
single column or for many columns?
