阻止插入操作并在 oracle 中记录对另一次审计 table 的尝试

Question

我想在晚上 7 点到凌晨 12 点之间阻止插入操作。一切正常，除了触发器在插入审计 table 之前触发异常。我的问题是如何才能同时阻止操作和记录尝试？

这是我试过的。

    Attempt_Date        DATE,
    Operation       VARCHAR2(10),
    Table_Affected  VARCHAR2(10));


Create or replace trigger audit_trigger 
Before insert or update on rents 
declare
    Period_error EXCEPTION;
BEGIN
    If TO_CHAR( sysdate, 'HH24MMSS' ) BETWEEN '060000' AND '100000' THEN
    begin
        RAISE Period_error;
                IF INSERTING THEN
                    INSERT INTO Rent_Audit VALUES (SYSDATE, 'Insert', 'Rents');
                End if;
            
                IF UPDATING THEN
                    INSERT INTO Rent_Audit VALUES (SYSDATE, 'Update', 'Rents');
                End if;
            
    EXCEPTION
        When Period_error THEN
            RAISE_APPLICATION_ERROR (-20001, 'insertion not allowed on this time');
    end;
    end if;
END;```

如果你想记录它，那么

触发器必须是自治事务（否则 RAISE 也会阻止插入 rent_audit）
- 这也意味着它必须 commit
在您向 rent_audit

像这样：

CREATE OR REPLACE TRIGGER audit_trigger
   BEFORE INSERT OR UPDATE
   ON rents
DECLARE
   period_error  EXCEPTION;
   PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
   IF TO_CHAR (SYSDATE, 'HH24MMSS') BETWEEN '060000' AND '100000'
   THEN
      BEGIN
         IF INSERTING
         THEN
            INSERT INTO rent_audit
                 VALUES (SYSDATE, 'Insert', 'Rents');
         END IF;

         IF UPDATING
         THEN
            INSERT INTO rent_audit
                 VALUES (SYSDATE, 'Update', 'Rents');
         END IF;

         COMMIT;
         RAISE period_error;
      EXCEPTION
         WHEN period_error
         THEN
            raise_application_error (-20001,
                                     'insertion not allowed on this time');
      END;
   END IF;
END;
