Thank you Adrian and others -
I am trying to replace INSERT into temp table in my custom function by RETURN NEXT, but get an error:CREATE OR REPLACE FUNCTION words_check_words(-- INSERT INTO _words(word, score)
IN in_uid integer,
IN in_gid integer,
IN in_tiles jsonb)
RETURNS TABLE(word varchar, score integer) AS
$func$
.......
-- VALUES (upper(_word), _score);
RETURN NEXT (word, score);
ERROR: RETURN NEXT cannot have a parameter in function with OUT parameters
LINE 98: RETURN NEXT (word, score);
This was limit in older version
you have to assign values to these variables and call RETURN NEXT without any parameters
CREATE OR REPLACE FUNCTION public.foob(OUT a integer, OUT b integer)
RETURNS SETOF record
LANGUAGE plpgsql
AS $function$
BEGIN
a := 10; b := 20;
RETURN NEXT;
b := 30;
RETURN NEXT;
END;
$function$
CREATE OR REPLACE FUNCTION public.foob(OUT a integer, OUT b integer)
RETURNS SETOF record
LANGUAGE plpgsql
AS $function$
BEGIN
a := 10; b := 20;
RETURN NEXT;
b := 30;
RETURN NEXT;
END;
$function$
result
┌────┬────┐
