  l_next_run_date      DATE;
  l_start_date_str     VARCHAR2(100);
  FOR i IN 1 .. p_iterations LOOP
    l_start_date_str := ‘TO_DATE(‘’’ ||
                         TO_CHAR(l_start_date, ‘DD-MON-YYYY HH24:MI:SS’)
                         ‘’’,’’DD-MON-YYYY HH24:MI:SS’’)’;
    l_interval := REPLACE(LOWER(p_interval), ‘sysdate’, l_start_date_str);
    EXECUTE IMMEDIATE ‘SELECT ‘ || l_interval || ‘ INTO :return FROM dual’
      INTO l_next_run_date;
    DBMS_OUTPUT.put_line('Next Run Date: ' || l_next_run_date);
    l_start_date := l_next_run_date;
