I haven't worked with bulk inserts much, so anyone who has please feel free to
respond with an improved solution using bulk inserts.

The only reason that I can think of to import into the same schema is to maybe
prevent the rollback segment from filling up undo or you are getting snapshot
too old. If you are having trouble with too many rows on the insert, then you
just need to code the insert in pl/sql with intermediate commits.
DECLARE
CURSOR c1 IS
SELECT *
FROM source_table;
row_cnt NUMBER := 0;
BEGIN
FOR r1 IN c1 LOOP
INSERT INTO destination_table
VALUES (r1.col1, r1.col2, ... r1.coln);
row_cnt := row_cnt +1;
IF row_cnt > 1000 THEN
COMMIT;
row_cnt := 0;
END IF;
END LOOP;
COMMIT;
END;
/
Just change the 1000 to a higher or lower number depending on your
requirements. Change source_table and destination_table to the real table
names and col1, col2, .. to the real column names.

I have an Oracle 9i (9.2.0.7.0) database.
One question on table export.
Can we export a table and import into another table (which has the same
structure)?
Both the tables are in the same schema.
Thanks,
