Hi!
Thank you.

Use a CTE and move the function call to the select list - then explode the result in the main query.

I tried in 9.5
CREATE or replace FUNCTION crtKAIVE(
_doktyybid text default 'GVY'
)
RETURNS TABLE (
id integer
)
AS $f_crkaive$
select 1
$f_crkaive$ LANGUAGE sql STABLE;
create temp table ko ( doktyyp text ) on commit drop;
insert into ko values ('G');
WITH func_cte AS (
SELECT crtKAIVE(ko.doktyyp)
FROM ko
)
SELECT (crtKAIVE).*
FROM func_cte;
but got strange error
ERROR: syntax error at or near ""
LINE 18: )
How to fix ?
Andrus.
