Calling another function if upate statement fails

Question

Hi there,
I have written an update procedure and insert procedure. Is there a way of calling another function if the update statement fails? Thanks a lot for your help.

procedure update_costing(in_period in DATE,
               in_project_id IN VARCHAR2,
               in_user_id IN VARCHAR2,
               in_thu IN VARCHAR2,
               in_fri IN VARCHAR2,
               in_sat IN VARCHAR2,
               in_sun IN VARCHAR2,
               in_mon IN VARCHAR2,
               in_tue IN VARCHAR2,
               in_wed IN VARCHAR2)
     UPDATE TBL_COSTING
          SET
               HOURS_THU = to_date (in_thu, 'HH24:MI'),
               HOURS_FRI = to_date (in_fri, 'HH24:MI'),
               HOURS_SAT = to_date (in_sat, 'HH24:MI'),
               HOURS_SUN = to_date (in_sun, 'HH24:MI'),
               HOURS_MON = to_date (in_mon, 'HH24:MI'),
               HOURS_TUE = to_date (in_tue, 'HH24:MI'),
               HOURS_WED = to_date (in_wed, 'HH24:MI'),
               WHERE PERIOD = in_period
     AND PROJECT_ID = in_project_id
     AND USER_ID = in_user_id;
EXCEPTION
--CALLL HERE THE INSERT FUNCTION WITH SAME DATAMEMBERS
SOMETHING LIKE THIS---
WHEN others then
     insert_costing(in_period, in_project_id, in_user_id ,in_thu,in_fri,in_sat,in_sun,in_mon,in_tue,in_wed ,in_submit);
COMMIT;
END update_costing;

begin
UPDATE statement
IF SQL%ROWCOUNT =0
then
INSERT statement|procedure
end if;
end;
/Hi,
i have a simple doubt over here, i read somewhere that cursor attributes can be used only as long as the cursor is open, then in the above case whiel doing the update operation, oracle implicitly will open an cursor and will do the operation and then will close the cursor, then how does SQL%ROWcount works???please revert...
