Are people here talking about UUIDs or things that just look like UUIDs? It sounds like the latter. UUIDs are actually structured objects, with embedded type bits. There are multiple UUID generation schemes, one of which is based on random numbers, others are based on hashes, and there is the common ugly workaround of generating a 128 bit hash and calling it a UUID.
If you use version 1 UUIDs you're mathematically guaranteed to avoid collisions. At least for the next 3000 years: Version 1 UUIDs are based on a node address (MAC), a 60 bit clock, and a node-specific sequence number. You can generate 163 billion version 1 UUIDs per second and they won't roll over until 5236 AD. _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
