如何使用 %ROWTYPE 获取游标值

我做了一个如下所示的过程，我想获取游标值并从其他循环中提取这些值告诉我最好的方法是我的代码

 CREATE OR REPLACE PROCEDURE TEST (P_EMP_ID     NUMBER,
                                                  TRIGER_BY    VARCHAR2)
AS
   CURSOR TO_HOD
   IS
      SELECT   EMP.EMPLOYEE_CODE,
               EMP.EMP_NAME,
               APR.LEFT_DT,
               APR.RESIGN_TYPE
        FROM   FSC_APPROVAL APR, CHR_ALL_EMPLOYEE_BI_V EMP
       WHERE       APR.HOD_APPR = 'Y'
               AND APR.ZONE_HD_APPR IS NULL
               AND EMP.EMPLOYEE_ID = APR.EMP_ID;

   CURSOR TO_ZONE
   IS
      SELECT   EMP.EMPLOYEE_CODE,
               EMP.EMP_NAME,
               APR.LEFT_DT,
               APR.RESIGN_TYPE
        FROM   FSC_APPROVAL APR, CHR_ALL_EMPLOYEE_BI_V EMP
       WHERE       APR.HOD_APPR = 'Y'
               AND APR.ZONE_HD_APPR = 'Y'
               AND APR.TIM_OFC_APPR IS NULL
               AND EMP.EMPLOYEE_ID = APR.EMP_ID;

   CUR_VAL            TO_HOD%ROWTYPE;
   CUR_VAL_FOR_LOOP   TO_HOD%ROWTYPE;

程序从这里开始

    BEGIN

       IF TRIGER_BY = 'HOD'
       THEN
          OPEN TO_HOD;

          LOOP
             FETCH TO_HOD INTO   CUR_VAL;

             EXIT WHEN TO_HOD%NOTFOUND;
          END LOOP;
       ELSIF TRIGER_BY = 'ZONE'
       THEN
          OPEN TO_ZONE;

          LOOP
             FETCH TO_ZONE INTO   CUR_VAL;

             EXIT WHEN TO_ZONE%NOTFOUND;
          END LOOP;

   END IF;

在上面的代码中只需获取我的数据并放入cur_val那是%rowtype 之后我在新循环中获取这些值，但它没有意义并显示错误PLS-00456: 项目“CUR_VAL”不是游标

LOOP
      ***FETCH CUR_VAL INTO   CUR_VAL_FOR_LOOP;***

      DBMS_OUTPUT.PUT_LINE (CUR_VAL_FOR_LOOP.EMPLOYEE_CODE);
   END LOOP;
END;
/

我在这条线上遇到错误FETCH CUR_VAL INTO CUR_VAL_FOR_LOOP;请指导我如何按照我的意愿进行此过程如果您有更好的选择那么我热烈欢迎如果您对我的问题有进一步的疑问那么我将在这里向您描述

为什么使用两个变量？你可以做得更短（未经测试）：

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;
