Cara mengambil nilai kursor dengan %ROWTYPE

Mengapa Anda menggunakan dua variabel? Anda dapat melakukannya lebih pendek (tidak diuji):

CURSOR TO_ALL(hd APR.ZONE_HD_APPR%TYPE) IS
  SELECT   EMP.EMPLOYEE_CODE,
           EMP.EMP_NAME,
           APR.LEFT_DT,
           APR.RESIGN_TYPE
    FROM   FSC_APPROVAL APR, 
              JOIN CHR_ALL_EMPLOYEE_BI_V EMP ON EMP.EMPLOYEE_ID = APR.EMP_ID
   WHERE   APR.HOD_APPR = 'Y'
           AND NVL(APR.ZONE_HD_APPR, 'NULL') = NVL(hd, 'NULL')
           AND EMP.EMPLOYEE_ID = APR.EMP_ID;

CUR_VAL TO_ALL%ROWTYPE;

BEGIN

      OPEN TO_ALL(CASE TRIGER_BY WHEN 'HOD' THEN 'NULL' ELSE 'Y');
      LOOP
         FETCH TO_ALL INTO   CUR_VAL;
         ...
         EXIT WHEN TO_ALL%NOTFOUND;
      END LOOP;

END;
