This note demonstrates how to export single partitions from a table using the DataPump API. The environment is the following one:

connect / as sysdba

-- Create user
drop user test_part cascade;
purge dba_recyclebin;
create user test_part identified by test_part default tablespace users temporary tablespace temp;
grant connect, resource to test_part;

-- Create directory object
create or replace directory dpudir as '/tmp';
grant read, write on directory dpudir to test_part;

-- Create a partitioned table in new created schema
connect test_part/test_part
create table a_tab
   id   number,
   text varchar2(100)
partition by range (id)
   partition p001 values less than (10),
   partition p002 values less than (100),
   partition p003 values less than (1000),
   partition p004 values less than (10000),
   partition p005 values less than (maxvalue)

-- Populate the table
  for i in 1..10000 loop
    insert into a_tab values (i, 'Text '||lpad (to_char (i), 95, '0'));
  end loop;

-- Verify the table partitions
connect / as sysdba
col table_owner format a10
col table_name format a10
col partition_name format a10
select table_owner, table_name, partition_name
from   dba_tab_partitions
where  table_owner = 'TEST_PART' and
       table_name = 'A_TAB'
order  by table_owner, table_name, partition_position;

This shows:

---------- ---------- ----------
TEST_PART  A_TAB      P001
TEST_PART  A_TAB      P002
TEST_PART  A_TAB      P003
TEST_PART  A_TAB      P004
TEST_PART  A_TAB      P005

5 rows selected.
