Tables created with CREATE TEMPORARY TABLE disappear when the current
connection closes.  They also are visible only within the connection that
created them.


- If you create the table from one page using a non-persistent connection,
   the connection will close when the script ends and the table will
   disappear and be unavailable to other pages.
- If you create the table from one page using a persistent connection, the
   connection will not *necessarily* close when the script ends.  However,
   there is no guarantee that a following page will get that same connection,
   in which case the table will not be visible even if it happens to still
