Hi,
I need to make *allot* of queries from a application dealing with IP
Addresses. At the moment, I'm storing IP addresses as a VARCHAR(16).
I would *like* to store them as Integers by converting the IP to it's
numerical equivalent. I believe this would also save a enormous
amount of table space.
The problem is, I *must* do the conversion as part of my SQL Query.
Either during the SELECT/UPDATE/INSERT, or via a Procedure... And I
must obviously also be able to convert the Integer back into a IP
address during queries....
Is this at all possible???
mytable
MySQL has dotted IP string to integer (and vice versa) conversion
functions. You'd use them in queries like:
insert into mytable set IPaddress = funcName('192.168.191.34');
select funcName(IPaddress) as strIPaddress, IPaddress as intIPaddress
from mytable;
I suspect you posted to the list before attempting to the functions in
the online documentation so I'll simply confirm they exist and leave
you to: Do Your Own Research by Reading The Fine Manual.
