Storing ROWID in a ROW_ID field.

Question

I'm attempting to restore a ROWID after an import/export and i'm unsure if this is the correct way to it. As well i think there may be something wrong with my function that restores the poper ROWID's. Is there a better way to do this? Is my function correct?
Here is the code i'm trying to use to restore the ROW_ID field after an export/import:
create or replace PROCEDURE FIXROWID AS
BEGIN
declare
cursor cur_t is SELECT * FROM SLC_TILLAGE_LANDFORM;
rec_tillage SLC_TILLAGE_LANDFORM%rowtype;
begin
open cur_t;
loop
fetch cur_t into rec_tillage;
UPDATE SLC_TILLAGE_LANDFORM
SET ROW_ID = ROWID
WHERE PROVINCE = rec_tillage.PROVINCE AND
SL = rec_tillage.SL AND LANDFORM = rec_tillage.LANDFORM;
COMMIT;
exit when cur_t%notfound;
end loop;
end;
END FIXROWID;
Here is the table in question:
PROVINCE VARCHAR2(2 BYTE)     
SL     NUMBER
LANDFORM VARCHAR2(50 BYTE)     
LANDFRM_EX VARCHAR2(11 BYTE)          
TEL     NUMBER(6,1)     
ROW_ID     ROWID          
LE_CODE     NUMBER(1,0)          
LANDPROP NUMBER(5,2)

Answer 1

use it to update a field quicklyUpdating using rowid? That's scary. Hope you know that there is a possibility that the rowid can change. Anyway in your case you must just need a simple UPDATE.
UPDATE SLC_TILLAGE_LANDFORM
SET ROW_ID = ROWID;
