Re: Generating a GUID

In OO environments the GUID concept is quite frequent. In OO persistence environments the GUID concept is ALWAYS present. I find really strange that Oracle8i with it's O-R model does not provide a way to generate it...

Anyway, how does Oracle8i manage a situation where you export a table of objects an a table that has references to that objects and than you import that rows in another Db (with the same schema)? How doest it assure that OIDs from the two Db don't collide?
