如何使用％ROWTYPE获取游标值 [英] How to fetch cursor value with %ROWTYPE

问题描述

我进行如下所示的操作，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

i make a procedure as shown below i want to fetch cursor values and extract these values from other loop tell me best way here is my code

 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;

从这里开始程序

    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;

上面的代码中

只是获取我的数据并放入％rowtype的 cur_val 之后，我在新循环中获取这些值，但没有意义并显示错误 PLS-00456:项目'CUR_VAL'不是游标

in above code just fetch my data and put in cur_val that was %rowtype after that i fetch these values in new loop but its not make sense and show error PLS-00456: item 'CUR_VAL' is not a cursor

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

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

我在此行FETCH CUR_VAL INTO CUR_VAL_FOR_LOOP;上遇到错误 如果您有更好的选择，请按照我的意愿指导我如何执行此过程，如果您对我的问题有进一步的疑问，我将热烈欢迎，然后在这里我向您描述

i am face error on this line FETCH CUR_VAL INTO CUR_VAL_FOR_LOOP; please guide me how i make this procedure as i desire if you have better option then i warmly welcome if you have further query about my Question then i will here to describe you

推荐答案

为什么要使用两个变量?您可以做的更短(未经测试):

Why do you use two variables? You can do it shorter (not tested):

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;
