"Temporary tables" are nothing special - it's just a trick up your
sleeve, a tool in your toolbox, for handling certain situations. You
create the temporary table when you need it, and drop it when you're
done using it. Now in MySQL 3.23 there is explicit support for this
practice, using the CREATE TEMPORARY TABLE foo (...) statement, which
handles dropping the table for you automatically. But essentially
it's nothing special. You still create them and access them just like
every other table.
