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
thissample 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
todeclare 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);
