Update the database table with the content of the internal table

Question

Hello!
  I have the next form:
  FORM erase_data.
SELECT * FROM zadrress INTO CORRESPONDING FIELDS OF TABLE itab_adrress.
  DELETE TABLE itab_adrress: FROM zadrress,
                             WITH TABLE KEY adrid = '456'.
  WRITE 'The information after the DELETE operation'
  COLOR 2.
  LOOP AT itab_adrress INTO wa_adrress .
    WRITE:/
           wa_adrress-adrid COLOR 5,
           wa_adrress-name COLOR 7,
           wa_adrress-email COLOR 5,
           wa_adrress-depart COLOR 7,
           wa_adrress-display COLOR 5.
  ENDLOOP.
  SKIP.
LOOP AT itab_adrress INTO wa_adrress.
   MODIFY zadrress FROM wa_adrress.
   COMMIT WORK.
   IF sy-subrc = 0.
     WRITE 'OK !'.
     SKIP.
   ELSE.
     WRITE 'FAIL !'.
     SKIP.
   ENDIF.
ENDLOOP.
  MODIFY zadrress FROM TABLE itab_adrress.
  UPDATE zadrress FROM TABLE itab_adrress.
TRANSPORTING adrid, name, email, depart, display.
INSERT zadrress FROM TABLE itab_adrress ACCEPTING DUPLICATE KEYS.
PERFORM display_data .
ENDFORM.                    "erase_data
I see that my record is deleted  when I display the records from my internal table, but
now I want to delete the record from database table.
   For that I want to move the content of the modified internal table in the database table. You can see the methods I tried (some of them commented), but nothing seems to work.
Any advice ?
Thank you.
