=>From: Kaj-Michael Lang <milang@tal.org> =>... =>I have stored IP's in a table using a varchar(15) field. My problem is how =>to make the order by list the IP's the correct order like: => =>192.168.1.1 =>192.168.1.6 =>192.168.1.10 => =>now it sorts them like: => =>192.168.1.1 =>192.168.1.10 =>192.168.1.6 => =>is it possible to get them sorted the right way ? There may be a special function (or you could write one) to sort numbers which are represented as varchars, but a better solution would be to re-store the IP numbers as integers. This will also allow you to work on them with netmasks and so forth. Convert them back to A.B.C.D when you print them out. d.
