That will work, slowly.

You might like to try something like this

insert into resource
nologging
select * from rqmt
append;

Read up on the 'append' and 'nologging' first.

        Subject:        insert and commit 1000 records at a time

I have 2 tables, Rqmt and Resource, same structure.

I need to take all almost-one-million records from Rqmt and insert them to Resource. So far this worked ok:

DECLARE
RowCount NUMBER := 0;

BEGIN

     SELECT Count(*)
     INTO   RowCount
     FROM   RQMT;

     IF RowCount > 0 THEN

         INSERT INTO RESOURCE
             SELECT  Resource_Id, Classification
             FROM RQMT;

         RowCount      := SQL%RowCount;

         DBMS_OUTPUT.PUT_LINE ('TABLE Resource: '  || RowCount || ' Rows 
transitioned.');
         COMMIT;
     ELSE
         DBMS_OUTPUT.PUT_LINE ('TABLE Resource is empty. No data 
transitioned.');
     END IF;

     EXCEPTION
     WHEN OTHERS THEN
         Raise;

END;
/

But now I need to commit every 1000 records. Any suggestions as to what would be the best way? I dont think ROWNUM would help here, because it would pick the same 1000 records every time, causing primary key violation...

thx
maa
