Re: time/date as key fields

Dieter,

Do you have any reference that says that a UUID from _GENUUID is not unique?

http://publib.boulder.ibm.com/infocenter/iseries/v6r1m0/index.jsp?topic=/rzatk/GENUUID.htm says it is.

Are you saying it is not?

Thanks,

Crispin.

... it depends, maybe for referential constraints, if there are database
relations.
BTW: genUUID on AS/400 is only most likely unique!!! Best choice would be an
identity column, if uniqueness is needed.
