Re: inner join problem with temporary tables

could you please give me an example?.
How could i make an inner join select with temporary tables?

This function does not work:

REATE OR REPLACE FUNCTION modelo.test2(OUT xart_cod character varying, OUT xart_descri character varying)
RETURNS SETOF record AS
$BODY$
begin
create temp table t_arti as (select art_cod,art_descri from modelo.articulos);
select $1,$2 from t_arti ;
end;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;

this is the error message:

ERROR: query has no destination for result data
SQL state: 42601
Hint: If you want to discard the results of a SELECT, use PERFORM instead.
Context: PL/pgSQL function "test2" line 4 at SQL statement
