Help summarizing a series of numbers

Question

Hello,
The following SQL gives the output as
450039 - 450090
450041 - 450041
WITH wsh_Serial_numbers as
( select
72016 delivery_detail_id , 450039 fm_serial_number, 450039 to_serial_number from dual
union all
select 72016 ,450040, 450040 from dual union all
select 72016, 450041, 450041 from dual union all
select 72016, 450089 ,450089 from dual union all
select 72016 ,450090 ,450090 from dual )
SELECT from_num||' - '||to_num Serial_Numbers
FROM
WITH all_data1 AS
SELECT delivery_detail_id detail_id,
fm_serial_number f_serial_no ,
to_serial_number t_serial_no ,
NVL(lead(fm_serial_number) over (partition BY delivery_detail_id order by fm_serial_number)-fm_serial_number,1) lead
--NVL(fm_serial_number-lead(fm_serial_number) over (partition BY delivery_detail_id order by fm_serial_number),1) lead
FROM wsh_Serial_numbers all_data1
WHERE delivery_detail_id = 72016--p_delivery_detail_id
ORDER BY delivery_detail_id
SELECT detail_id ,
MIN(f_serial_no) FROM_num,
MAX(f_serial_no) TO_NUM
FROM all_data1
GROUP BY detail_id, lead
ORDER BY MIN(f_serial_no)
But the desired result is
450039 - 450041
450089 - 450090
Could some one suggest how do I get this result?
Regards,
Srini
