Oh...thanks one more question.
I create these function:
CREATE FUNCTION sum_revenue() RETURNS real AS '
DECLARE
call RECORD;
BEGIN
tmpsum := 0;
FOR call IN SELECT
country,(date_part('epoch), starttime - endtime)::float AS seconds ,type from calls where sub_acc = 4
LOOP
RETURN call.minutes;
END LOOP;
end;
' LANGUAGE 'plpgsql';
And in call.minutes i've got '0';
Why ? How can i retrive call.minutes ?
these RETURN only for debug.
