If it's a lot of rows and looks like you are archiving it to a historical table, you could do:

insert /*+ append */ into target_table select * from source_table;

this will do a direct path insert, so it uses space above HWM. It doesn't generate redo.

Hi all,

Please forgive this newbie question; I'm just getting started with PL/SQL. I want to write a procedure to copy all rows from one table to another one with an identical structure. The table has many rows so I'm committing every thousand records (error handling to be added later). The table has 50+ columns and (if possible) I'd like to avoid listing them all in the VALUES clause. I'm not just being lazy - I hope to deploy this code to several databases and the source table, while having the same name, may have differences in the columns. I want to do something like this:

DECLARE
count_ NUMBER;
CURSOR get_archive_records IS

      SELECT * FROM customer_order_table; BEGIN
   count_ := 0;
   FOR rec_ IN get_archive_records LOOP

      INSERT INTO customer_order_archive
      VALUES (rec_.*);     -- OBVIOUSLY, THIS DOES NOT WORK
      count_ := count_ + 1;
      IF MOD(count_,1000) = 0 THEN
         COMMIT;
      END IF;

END LOOP;
COMMIT;
END; Is there a way to accomplish this? Or is my whole approach all wrong?

Thanks in advance,
Beth
