[SQL] Using a RETURN NEXT

[Mr Weinbach, Larry]

Hi all,

I found this example from Postgres site

create or replace function GetRows(text) returns setof
record as
'
declare
    r record;
begin
    for r in EXECUTE ''select * from '' || $1 loop
        return next r;
    end loop;
    return;
end
'
language 'plpgsql';


I am trying to use the same idea but in this way ..

CREATE OR REPLACE FUNCTION word_case() RETURNS setof
RECORD AS'
DECLARE
  reg record;
  BEGIN
     FOR reg IN SELECT message FROM rtable LOOP
            RETURN next reg;
     END LOOP;
    RETURN;
  END;
' LANGUAGE 'plpgsql';

But at execution time I am getting thi error :

WARNING:  Error occurred while executing PL/pgSQL
function word_case
WARNING:  line 5 at return next
ERROR:  Set-valued function called in context that
cannot accept a set

I also tried using my own type defined but I got the
same error.

Any hint or idea will be appreciated ...

Regards

Larry
