How to use row values as function parameters

Table ko should used to pass parameters to crtKAIVE() function.
ko has always single row.

I tried

CREATE or replace FUNCTION public.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');
select * from ko, crtkaive(ko.doktyyp)

but got error

ERROR: function expression in FROM cannot refer to other relations of
same query level

How to fix this so that ko can used to pass parameters to crtkaive ?
