Hi,
I' still with my stored procedure :
-- Function: SP_U_001(typeofarticle varchar)
-- DROP FUNCTION SP_U_001(typeofarticle varchar);
CREATE OR REPLACE FUNCTION SP_U_001(IN typeofarticles VARCHAR)
RETURNS SETOF active_articles AS
$BODY$
DECLARE
myrec RECORD;
res active_articles;
/**************************************/
BEGIN
FOR myrec IN
select *
from articles, articletypes, department
where
articletypes.articletype_type = $1
AND articles.articletype_id = articletypes.articletype_id
AND articles.department_id = department.department_id
AND articles.validity_period_end
> now()
LOOP
IF (myrec IS NOT NULL) THEN
res.article_type := myrec.articletypes.articletype_type;
res.article_author := myrec.articles.author;
res.department_owner := myrec.department.department_name
;
res.department_picture := myrec.department.department_picture;
res.article_title := myrec.articles.title;
res.article_content := myrec.articles.content;
res.date_creation := myrec.articles.creation_date
;
res.date_start := myrec.articles.validity_period_start;
res.date_end := myrec.articles.validity_period_end;
END IF;
RETURN NEXT res;
END LOOP;
RETURN;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
ALTER FUNCTION SP_U_001(VARCHAR) OWNER TO immensesk;
GRANT EXECUTE ON FUNCTION SP_U_001(VARCHAR) TO immensesk;
whatever, i do the argument VARCHAR will be stored in double quote as "varchar" when i check via pgAdmin GUI. Even if in command line it looks like above.
I still have the same error message on "myrec" :
ERROR: schema "myrec" does not exist
CONTEXT: SQL statement "SELECT myrec.articletypes.articletype_type"
i do not understand as there is quite the same example in postgreSQl
8.1.4 documentation on page 623-624 about "Looping Through Query Results".
so where am i wrong ?
Al.
