请问我想查询某个IP段之间(如192.168.0.1-192.168.0.255 是一个IP段 而 198.168.1.1-192.168.1.255 是另一个IP段)都有那些IP怎么写SQL语句?
假若我要查询 192.168.0.1-192.168.0.255 这个IP断那么就应该市
IP
198.168.0.1
192.168.0.5
192.168.0.15
192.168.0.215
------解决方案--------------------select * from A
where ip like '192.168.0.% '
------解决方案--------------------加个条件不就行了呀
create table A(ip varchar(20))
insert A select '198.168.0.1 '
union all select '192.168.0.5 '
union all select '192.168.0.15 '
union all select '192.168.0.215 '
union all select '192.168.1.5 '
union all select '192.168.1.25 '
union all select '192.168.1.23 '
union all select '192.168.1.155 '
union all select '192.168.2.5 '
union all select '192.168.2.53 '
union all select '192.168.2.223 '
select * from A
where ip like '192.168.0.% '
and cast(substring(ip,11,3) as tinyint) between 56 and 255
