SQL function and "UPDATE...RETURNING"

[Vincenzo Romano <vincenzo.romano@xxxxxxxxx>]

Hi all.

Is there a way to write an SQL function like this:

create or replace function afunction( recid bigint )
returns bigint as $body$
update atable set afield=0 where recid=$1 returning anotherfield;
$body$ language SQL;

If i write the function this way, postgres will complain that
the update stetement won't return values.

I also understand that by switching to PLPGSQL I would b able to
do write the function. But I'd prefer SQL in this case.
