[pyar] Nombres unicos para tablas

[Mariano Guerra]

If the "TEMP" or "TEMPORARY" keyword occurs in between "CREATE" and
"TABLE" then the table that is created is only visible within that
same database connection and is automatically deleted when the
database connection is closed. Any indices created on a temporary
table are also temporary. Temporary tables and indices are stored in a
separate file distinct from the main database file.
