Rem  External tables meta data: external_tab$, external_location$
Rem
Rem  Default directory is optional at the table and fragment levels.
Rem  default_dir is set to the specified table(fragment) level 
Rem  default directory, in the table(fragment) level row. default_dir is
Rem  NULL in the table(fragment) level row for the table(fragment),when
Rem  unspecified.
Rem
Rem  Access driver type for the table is mandatory in DDL.So type$ is always 
Rem  set in the table level row.It is NULL(unused) in fragment level rows
