导读：select "ID","START_IP","END_IP" from (with temp0 as (select LEVEL lv from dual CONNECT BY LEVEL = 100) select ID,substr(t.vals,instr(t.vals,',1,tv.lv) + 1, instr(t.vals,tv.lv + 1) -( instr(t.vals,tv.lv) + 1) ) AS start_ip, substr(t.vals1,in

select "ID","START_IP","END_IP" from (with temp0 as (select LEVEL lv from dual CONNECT BY LEVEL <= 100)
select ID,substr(t.vals,instr(t.vals,',1,tv.lv) + 1,
instr(t.vals,tv.lv + 1) -(
instr(t.vals,tv.lv) + 1)
) AS start_ip,
substr(t.vals1,instr(t.vals1,
instr(t.vals1,tv.lv + 1) -(
instr(t.vals1,tv.lv) + 1)
) AS end_ip
from (select ID,' || start_ip || ',' AS vals,
length(start_ip || ',') - nvl(length(REPLACE(start_ip,')),0) AS cnt,
',' || end_ip || ',' AS vals1,
length(end_ip || ',') - nvl(length(REPLACE(end_ip,0) AS cnt1

from HOST_WEBSITE_INFO) t join temp0 tv

on tv.lv <= t.cnt order by 1)

注：功能分割start_ip，end_ip
