The poster who said you cannot do CREATE TEMPORARY ... ENGINE=MEMORY is
The poster who noticed the "errno: 13" message is on the right track.
Even though MEMORY tables store their data and their indexes (yes, even
temporary MEMORY tables may be indexed) they still need to create a .frm
file within the folder of the database in which you are creating the
table. Check that location for proper permissions.
