> MySQL has a statement <DROP TEMPORARY TABLE> that is meant to be the corollary to <CREATE TEMPORARY TABLE>.  The important aspect is that the inclusion of the TEMPORARY keyword in each bypasses the implicit transaction commit from DDL execution.  Currently we use <CREATE TEMPORARY TABLE>, which is ok for use within a transaction, but then <DROP TABLE> which causes an implicit commit (and actually causes an immediate failure within an XA transaction).  For MySQL we should use <CREATE TEMPORARY TABLE> and <DROP TEMPORARY TABLE>.
