(Not Daniel, but answering anyway ...)

No, Oracle does not have such a feature. But this ain't really about Oracle - it's about the SQL language. And AFAIK, there is no formal namespace capability in the language spec. However qualifying by 'schema' and liberal use of double quotes gets around most of that 'limitation'.

I couldn't comment about Oracle's future releases other than what they publish in white papers - even if they happened to tell me. (Speculate, perhaps, but that wouldn't be binding.)

That said .... namespaces are fun, aren't they! They allow one to have 17 different 'person's each exactly the same as the others, only different. No maintenance issue at all, because of the supporting docco developers leave behind when they finish the job and change companies. ;-)
