Is there any ability to work with SQL refcursor type?
e.g. we have function returning refcursor with data we need to insert into the template:
select Report0302.cCardStaff(idp, dpdate)
CREATE OR REPLACE FUNCTION Report0302.cCardStaff(idp numeric, dpdate timestamp without time zone)
RETURNS refcursor
LANGUAGE plpgsql
AS $function$
declare
p_cursor refcursor;
begin
open p_cursor for
select AllRep.*
from AllRep
where id = idp and dpdate between dbegin and dend
order by sLevel, nLevelOrder;
return p_cursor;
end;
$function$
;
now it results into the error
ОШИБКА: курсор "<unnamed portal 1>" не существует Query: select Report0302.cCardStaff(?::numeric,sysdate()) Parameters: [1.0]
It is a simple example, in reality we have difficult logic with dynamically changing querys, so just taking select-part to insert into the reporting tool is not an option.
