Hi
I have never worked with cursors but for now I have to step back on special
events to calculate a difference. So I have this sample code tested but I can
not "move" in my cursor. I have lokke at docs but this didn't help me. Can you
say how to declare my cursor to step back?
Thank You
Chris
PS code sample
create table fimi.eodbar(fi_id int8, market_id int8);
insert into fimi.eodbar values(322,200);
create or replace function fimi.test("fiid" int8) returns setof int as
$BODY$
DECLARE
cur1 REFCURSOR;
foo int;
BEGIN
OPEN cur1 FOR execute('select market_id from fimi.eodbar where fi_id=' ||
"fiid");
loop
fetch cur1 into foo;
if not found then
exit ;
else
-- move -1 in cur1;
fetch cur1 into foo;
return next foo;
end if;
end loop;
close cur1;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
ALTER FUNCTION fimi.getfoo(bpchar) OWNER TO fimi;
select * from fimi.test(322);
