I vote for the SQL92 TEMPORARY.  Let's not add a keyword that is non-standard
just because one or another commercial database makes use of it, unless
there's some real functionality to be gained that's not covered by the
standard.

TEMP is covered in SQL92 by TEMPORARY.

As an example of when adopting a construct from another commercial database
makes sense to me, SEQUENCE and SERIAL are both convenient means of generating
unique keys that have no equivalent in the standard.
