Question

运行此代码时，我收到错误消息。

INSERT INTO superheoes(sh_name) VALUES ('Supe');

======================================================================

I am getting the following Error message:

Error starting at line : 76 in command -

INSERT INTO superheoes(sh_name) VALUES ('Supe')

Error at Command Line : 76 Column : 13

Error report -

SQL Error: ORA-04098: trigger 'HR.SUPERHEROES_AUDIT' is invalid and failed re-

validation

04098. 00000 -  "trigger '%s.%s' is invalid and failed re-validation"

*Cause:    

A trigger was attempted to be retrieved for execution and was

           found to be invalid.  This also means that compilation/authorization

           failed for the trigger.

*Action:   Options are to resolve the compilation/authorization errors,

           disable the trigger, or drop the trigger.

然后插入值：

{{1}}

试试这个：它的工作原理。另请检查您是否拥有execute权限。

  SQL> SELECT   * FROM   DBA_SYS_PRIVS where grantee = 'SYSUSR' and privilege = 'EXECUTE ANY PROCEDURE' ;

    GRANTEE                        PRIVILEGE                                ADM
    ------------------------------ ---------------------------------------- ---
    SYSUSR                       EXECUTE ANY PROCEDURE                    NO

触发：

 CREATE OR REPLACE TRIGGER superheroes_audit
 BEFORE INSERT OR DELETE OR UPDATE
 ON superheoes
 FOR EACH ROW      
BEGIN
--   SELECT USER, TO_CHAR (SYSDATE, 'DD/MON/YYYY HH24:MI:SS')
--     INTO v_user, v_date
--     FROM DUAL;

   IF INSERTING
   THEN
      INSERT INTO sh_audit (new_name,
                            old_name,
                            user_name,
                            entry_date,
                            operation)
           VALUES (:NEW.sh_name,
                   NULL,
                   USER,
                   TO_CHAR (SYSDATE, 'DD/MON/YYYY HH24:MI:SS'),
                   'Insert');
   ELSIF DELETING
   THEN
      INSERT INTO sh_audit (new_name,
                            old_name,
                            user_name,
                            entry_date,
                            operation)
           VALUES (NULL,
                   :OLD.sh_name,
                   User,
                   TO_CHAR (SYSDATE, 'DD/MON/YYYY HH24:MI:SS'),
                   'Delete');
   ELSIF UPDATING
   THEN
      INSERT INTO sh_audit (new_name,
                            old_name,
                            user_name,
                            entry_date,
                            operation)
           VALUES (:NEW.sh_name,
                   :OLD.sh_name,
                   User,
                    TO_CHAR (SYSDATE, 'DD/MON/YYYY HH24:MI:SS'),
                   'Update');
   END IF;
END;

请参阅Demo for Trigger功能：

表：

CREATE TABLE superheoes (sh_name VARCHAR2 (20));

CREATE  TABLE sh_audit (new_name  varchar2(20),
                            old_name varchar2(20),
                            user_name varchar2(30),
                            entry_date varchar2(30),
                            operation varchar2(20));

执行：

SQL> select *  from superheoes;

no rows selected

SQL> select * from sh_audit;

no rows selected

SQL> insert into superheoes values('XING');

1 row created.

SQL> commit;

SQL> select * from sh_audit;

NEW_NAME             OLD_NAME             USER_NAME

21/DEC/2016 15:19:41           Insert

SQL> delete from superheoes;

1 row deleted.

SQL> commit;

Commit complete.

SQL> select * from sh_audit;

                     XING                 SYSUSR

如果我根据触发器创建表，则触发器在您编写时起作用：

CREATE TABLE superheoes (sh_name VARCHAR2(20));
CREATE TABLE sh_audit
(
    new_name                                VARCHAR2(20),
    old_name                                VARCHAR2(20),
    user_name                               VARCHAR2(20),
    entry_date                              VARCHAR2(20),
    operation                               VARCHAR2(20)
);
CREATE OR REPLACE TRIGGER superheroes_audit
    BEFORE INSERT OR DELETE OR UPDATE
    ON superheoes
    FOR EACH ROW
    ENABLE

DECLARE
    v_user                                  VARCHAR2(30);

    v_date                                  VARCHAR2(30);
BEGIN
    SELECT USER, TO_CHAR(SYSDATE, 'DD/MON/YYYY HH24:MI:SS')
      INTO v_user, v_date
      FROM DUAL;

    IF INSERTING
    THEN
        INSERT INTO sh_audit(
                             new_name,
                             old_name,
                             user_name,
                             entry_date,
                             operation
                            )
             VALUES (
                     :NEW.sh_name,
                     NULL,
                     v_user,
                     v_date,
                     'Insert'
                    );
    ELSIF DELETING
    THEN
        INSERT INTO sh_audit(
                             new_name,
                             old_name,
                             user_name,
                             entry_date,
                             operation
                            )
             VALUES (
                     NULL,
                     :OLD.sh_name,
                     v_user,
                     v_date,
                     'Delete'
                    );
    ELSIF UPDATING
    THEN
        INSERT INTO sh_audit(
                             new_name,
                             old_name,
                             user_name,
                             entry_date,
                             operation
                            )
             VALUES (
                     :NEW.sh_name,
                     :OLD.sh_name,
                     v_user,
                     v_date,
                     'Update'
                    );
    END IF;
END;
/

触发器已编译并正常工作：

SQL> INSERT INTO superheoes(sh_name) VALUES ('Supe');

1 row created.


SQL> select * from sh_audit;

NEW_NAME             OLD_NAME             USER_NAME            ENTRY_DATE           OPERATION
-------------------- -------------------- -------------------- -------------------- --------------------
Supe                                      ALEK                 21/DIC/2016 15:25:37 Insert

我会检查表结构，架构，权限......

Oracle 11g无法运行触发器和插入记录
