ORACLE ERROR PLS-00302: 与外部一起使用时必须声明组件 table

Question

我是 PLSQL 的新手，我想创建一个将记录插入 table(AUDIT_LOG ) 的过程，同时创建一个将记录插入 table 的文件。在将记录插入文件和数据库之前，会检查一些正则表达式 table.

select 语句匹配来自外部 table(EXT_TAB_AUDIT_LOG) 的记录。创建程序的代码如下：

CREATE OR REPLACE EDITIONABLE PROCEDURE "ABC"."PR_INSERT_AUDIT_LOG_FROM_FILE" (P_IMPORT_TIMESTAMP IN TIMESTAMP,
  IMPORT_FILE_NAME IN VARCHAR2)
AS

    CURSOR CUR_CORRECT_RECORDS_LIST IS 
        SELECT ID                   
        , TRIM(PRIMARY_NAME)
        , TRIM(PRIMARY_VALUE)
        , TERMINAL_DATE        
        , LAND_ID                        
        , P_IMPORT_TIMESTAMP
   FROM EXT_TAB_AUDIT_LOG AL
   LEFT OUTER JOIN VERFIY_NAME VWZ ON VWZ.VERFIY_TABLE_ID = TRIM(AL.VERFIY_TABLE_ID)
   WHERE REGEXP_LIKE (ID,'\d{2}-\d{2}-\d{2}')
   AND   PRIMARY_NAME IS NOT NULL
   AND   PRIMARY_VALUE IS NOT NULL
   AND   TERMINAL_DATE IS NOT NULL
   AND   LAND_ID IS NOT NULL;
   
   
   V_FILE   UTL_FILE.FILE_TYPE;
    V_LOGFILE_FILE_LINE        VARCHAR2(10000);
    I CUR_CORRECT_RECORDS_LIST%ROWTYPE;
   

BEGIN

   INSERT INTO AUDIT_LOG 
      ( ID                   
      , PRIMARY_NAME   
      , PRIMARY_VALUE  
      , TERMINAL_DATE
      , LAND_ID           
      )
   SELECT ID                   
        , TRIM(PRIMARY_NAME)
        , TRIM(PRIMARY_VALUE)
        , TERMINAL_DATE        
        , LAND_ID                        
        , P_IMPORT_TIMESTAMP
   FROM EXT_TAB_AUDIT_LOG AL
   LEFT OUTER JOIN VERFIY_NAME VWZ ON VWZ.VERFIY_TABLE_ID = TRIM(AL.VERFIY_TABLE_ID)
   WHERE REGEXP_LIKE (ID,'\d{2}-\d{2}-\d{2}')
   AND   PRIMARY_NAME IS NOT NULL
   AND   PRIMARY_VALUE IS NOT NULL
   AND   TERMINAL_DATE IS NOT NULL
   AND   LAND_ID IS NOT NULL;
   
   
   V_FILE := UTL_FILE.FOPEN('ABC_AL_IMPORTLOG', IMPORT_FILE_NAME, 'w');
   
   
   
   FOR I IN CUR_CORRECT_RECORDS_LIST
   LOOP


 V_LOGFILE_FILE_LINE := RPAD(NVL(I.ID,' '),8)
                  || RPAD(NVL(I.PRIMARY_NAME,' '),25)
                  || RPAD(NVL(I.PRIMARY_VALUE,' '),40)
                  || RPAD(NVL(to_char(I.TERMINAL_DATE,'yyyy-mm-dd-hh24.mi.ss.ff6'),' '),26)
                  || RPAD(NVL(I.LAND_ID,' '),3);
                  
      UTL_FILE.PUT_LINE(V_FILE,V_LOGFILE_FILE_LINE,true);
   END LOOP;
    
    UTL_FILE.FCLOSE(V_FILE);

   COMMIT;
EXCEPTION
   WHEN OTHERS
   THEN
      DECLARE
         V_PROCEDURE_NAME  VARCHAR2(30)  := $$PLSQL_UNIT;
         V_SUBJECT         VARCHAR2(255) := 'Error on DB procedure '||V_PROCEDURE_NAME||' on '||to_char(sysdate,'dd.mm.yyyy hh24:mi:ss');
         V_BODY            VARCHAR2(10000) := 'Hi all,'||chr(10)||chr(10)||'Procedure '||V_PROCEDURE_NAME||' returned the following error:'||chr(10)||SQLERRM;
      BEGIN
         SEND_MAIL ( 'GENERIC_DB_ERROR', V_SUBJECT,V_BODY);
         RAISE;
      END;  
END PR_INSERT_AUDIT_LOG_FROM_FILE;

每当我尝试编译上述过程时，我都会遇到编译时错误：

PLS-00302: component 'PRIMARY_NAME' must be declared

table 有列 PRIMARY_NAME，但我不知道为什么会出现此错误。任何人都可以通过可能的解决方案告诉我为什么我会收到此错误吗？

游标的列列表应该有列名或它们的别名；你的没有：

CURSOR CUR_CORRECT_RECORDS_LIST IS 
    SELECT ID                   
    , TRIM(PRIMARY_NAME)     --> should be primary_name
    , TRIM(PRIMARY_VALUE)    --> should be primary_value
    , TERMINAL_DATE
