插入视图时收到"ORA-01031:权限不足"错误

Question

在用户名'MY_ADMIN'下,我成功创建了一个名为'NOTIFICATIONS'的表和一个名为'V_NOTIFICATIONS'的视图.在'V_NOTIFICATIONS'视图中,我已成功创建了一个触发器和一个包,该包接受用户尝试插入视图并将其插入表中的内容.当用户尝试在视图上执行更新和删除功能时,"V_NOTIFICATIONS"触发器和包还会在表上执行更新和删除功能.

我在目前正在处理的项目中已经完成了许多视图,因为许多视图位于许多不同表的顶部,但是当尝试在此视图中插入记录时,我收到"ORA-01031:权限不足"错误.

我可以使用包中的相同代码直接插入表中,但不能直接插入到视图中.任何有关这方面的帮助将不胜感激.这是请求的代码:

视图:(当下面的UNION被注释掉时,包按预期运行)

CREATE OR REPLACE FORCE VIEW "MY_ADMIN"."V_NOTIFICATIONS" AS
  SELECT N_ID,
    NOTIFICATION_TYPE,
    CASE WHEN NOTIFICATION_DESC = 'C' THEN 'Copy' ELSE 'Send to' END NOTIFICATION_DESC,
    CASE WHEN CONTACT_TYPE = 'D' THEN 'Department' ELSE 'Contact' END CONTACT_TYPE,
    A.AU_USER_ID,
    A.CONTACT_NAME,
    D.DEPARTMENT_ID,
    D.DEPT_DESC
  FROM NOTIFICATIONS AN,
    (SELECT A1.AU_USER_ID,
            AU.FIRST_NAME || ' ' || AU.LAST_NAME CONTACT_NAME
       FROM APP_USERS_CONTACT_INFO A1,
            APPLICATION_USERS AU
      WHERE A1.AU_USER_ID = AU.USER_ID
    /*UNION
     SELECT 0,
            NULL
       FROM DUAL*/) A,
    (SELECT DEPARTMENT_ID, 
            DESCRIPTION DEPT_DESC
       FROM DEPARTMENTS
      UNION
     SELECT 0 DEPARTMENT_ID,
            NULL DEPT_DESC 
       FROM DUAL) D
  WHERE NVL(AN.AU_USER_ID,0)      = A.AU_USER_ID
    AND NVL(AN.D_DEPARTMENT_ID,0) = D.DEPARTMENT_ID;

包:

CREATE OR REPLACE PACKAGE NOTIFICATIONS_PKG AS

   PROCEDURE INSERT_NOTIFICATION(P_N_ROW V_NOTIFICATIONS%ROWTYPE);

END NOTIFICATIONS_PKG;
/
CREATE OR REPLACE PACKAGE BODY NOTIFICATIONS_PKG AS

   PROCEDURE INSERT_NOTIFICATION(P_N_ROW V_NOTIFICATIONS%ROWTYPE) IS

    L_NOTIFICATION_DESC    VARCHAR2(1);
    L_CONTACT_TYPE         VARCHAR2(1);

   BEGIN

      CASE P_N_ROW.NOTIFICATION_DESC
        WHEN 'Copy' THEN
          L_NOTIFICATION_DESC := 'C';
        ELSE
          L_NOTIFICATION_DESC := 'S';
      END CASE;

      CASE P_N_ROW.CONTACT_TYPE
        WHEN 'Department' THEN
          L_CONTACT_TYPE := 'D';
        ELSE
          L_CONTACT_TYPE := 'C';
      END CASE;

      INSERT INTO NOTIFICATIONS VALUES (
      P_N_ROW.N_ID,
      P_N_ROW.NOTIFICATION_TYPE,
      L_NOTIFICATION_DESC,
      L_CONTACT_TYPE,
      NVL(P_N_ROW.AU_USER_ID, 0),
      NVL(P_N_ROW.DEPARTMENT_ID, 0),
      APP_GLOBAL_PKG.GET_AUDIT);

   END INSERT_AGREEMENT_NOTIFICATION;
END AGREEMENT_NOTIFICATIONS_PKG;

设置触发器只是为了将信息传递给此包以插入行.在尝试运行以下代码行时,我收到ORA-01031错误:

INSERT INTO V_AGREEMENT_NOTIFICATIONS VALUES (5781, 'Collateral Request', 'Send to', 'Contact', 797, '797T', 0, null);

INSERT进入视图失败,因为您无法插入DUAL.不只是你,而是任何人.尝试

INSERT INTO DUAL (DUMMY) VALUES ('1')

看看会发生什么.

分享和享受.
