yes...it always has to match. the format string requirements could in
theory be relaxed (for 'get') but this would break symmetry with 'put'
and you would lose a sanity check...getf like scanf writes directly
into application memory so the double-specifying (directly in the
format string and indirectly in the query) isn't necessarily a bad
thing. imagine if your application was 'select * from table' and one
of the field types changed...disaster.
