in the above query i want my cursor to run the loop only once at the first true of
my condition....in the second run the tdate will be = '12-FEB-2005'....but my
cursor loop should not go in..it has to comeout....Simply control has been the cursor processed or not.
Something like that
SQL> declare
  2    tdate date := to_date('12-JAN-2005','DD-MON-YYYY');
  3    cursor cr is select * from dual;
  4    rt dual%rowtype;
  5    cursor_has_been_processed boolean := false;
  6  begin
  7   loop
  8     if to_date('10-JAN-2005','DD-MON-YYYY') <=tdate then
  9             if not cursor_has_been_processed then
10                     open cr;
11                     loop
12                     fetch cr into rt;
13                     exit when cr%notfound;
14                     end loop;
15                     close cr;
16                     cursor_has_been_processed := true;
17                     dbms_output.put_line('Cursor has been processed');
18             end if;
19     --DO something
20     null;
21          end if;
22     dbms_output.put_line(tdate);
23     tdate := add_months(tdate,1);
24     exit when tdate >= to_date('12-MAY-2005','DD-MON-YYYY');
25   end loop;
26  end;
