This works...
CREATE TABLE My_table_XT
  ORGANIZATION EXTERNAL
  (
     TYPE ORACLE_DATAPUMP
     default directory TEMP
     LOCATION ( 'My_table_xt.dmp' )
  )
  as
select * from all_objects;

and I can select from my_table_xt.

My question is, is it possible to take a .dmp file with several tables in it and create external tables using the single .dmp?

So, you create a dmp using exp and parameter file that defines 3 tables. You put the dmp in your directory...

is it possible to easily create 3 external tables?

Hi,

An external table is a "flat file". An export dump is a binary file. Don't think it could work.

Cheers,

PS. In your example, the ORACLE_DATAPUMP access driver creates such a "flat file"....

Confirming what was said above:  if the DMP file was created with an Oracle exp(or expdp), it is binary and can only be accessed by imp(or impdp).

Datapimp and old versions are not mix and match.  If exp created it, imp must be used to read it.
