Why not just do an insert?  

INSERT INTO <table_b> SELECT * FROM <table_a>;

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.  

    SELECT *
      FROM source_table;
  row_cnt NUMBER := 0;
  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

      row_cnt := 0;

    END IF;

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 ( 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.
