Subj:   Volatile vs. Global

Hi

Someone asked me why would you use a volatile table over a global? I know there are differences:

* On a global you can collects statistics and create Secondary indices which you can't on a volatile.

* A global uses temporary space for the data and perm space for the structure and a volatile uses spool space.

* One global structure can be created and shared by many but a volatile can not.

Because of the differences I could give you several reasons to use a global over a volatile but assuming that there is a little perm space available for the global structure and temp space for the data, why would a volatile table be better to use than a global?

Thanks in Advance
