** Attempt to open the file named in the argument as the auxiliary database

** separate databases and acting on them as if they were one.
**
** This routine closes the existing auxiliary database file, which will
** cause any previously created TEMP tables to be dropped.
**
** The zName parameter can be a NULL pointer or an empty string to cause
** a temporary file to be opened and automatically deleted when closed.
