This is example with HR user(example user in Oracle database) and Countries table. We'll extract a couple of rows with query - where region_id=2(table has 25 rows).
I created another user, HR2 and table Countries with same structure(but no FK constraints to ease import).
From HR we will export subset of Countries table and in HR2 we'll import the data.
