Subject: RE: CreateUUID()

Hello,

We rely heavily on UUID's. We use ColdFusion's UUID generator. As long as you have NIC the UUID is guaranteed to be universally unique for at least a few thousand years..

SQL 7 can also generate a GUID which is the same thing more or less.

The UUID generation algorithm uses the machines Mac address to make it universally unique so if you do not have a NIC then it can only be guaranteed unique to that one machine.
