I believe that this would be the best solution:
DECLARE
RowCount NUMBER := 0;BEGIN
/* This will work if the RESOURCE table has the "parallel"
attribute set. In 8i, table needs to be partitioned as well */ EXECUTE IMMMEDIATE 'ALTER SESSION ENABLE PARALLEL DML';
SELECT Count(*)
INTO RowCount
FROM RQMT;IF RowCount > 0 THEN
INSERT /*+ APPEND */ 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 NOT_LOGGED_ON;
END;

yeah dont commit every 1000 records and do it in one shot. this is going to be much slower.
why do you want to do it this way? Ive done 100m inserts with just an
insert select and one commit.
