我尝试更新client_master表但是它给出了一个错误Idk why.I确实更新了client_master set name =＆＃39; abc＆＃39;其中name =＆＃39; xyz＆＃39 ;;

  create or replace trigger client_audit before update or delete on client_master for each row
begin
    case 
        when updating then
            insert into audit_client values(:OLD.c_no,:OLD.name,:OLD.address,:OLD.bal_due,'upd','1',sysdate);
        when deleting then
            insert into audit_client values(:OLD.c_no,:OLD.name,:OLD.address,:OLD.bal_due,'delet','2',sysdate);
    end case;
end;

试试这个解决方案。希望这会有所帮助。

CREATE OR REPLACE TRIGGER client_audit before
  UPDATE OR
  DELETE ON client_master FOR EACH row 
  DECLARE
  BEGIN 
  IF UPDATING THEN
  INSERT
  INTO audit_client VALUES
    (
      :OLD.c_no,
      :OLD.name,
      :OLD.address,
      :OLD.bal_due,
      'upd',
      '1',
      sysdate
    );
ELSIF DELETING THEN
  INSERT
  INTO audit_client VALUES
    (
      :OLD.c_no,
      :OLD.name,
      :OLD.address,
      :OLD.bal_due,
      'delet',
      '2',
      sysdate
    );
END IF;
END;

当我创建一个触发器时，它会给出一个错误，指出它无效并且重新验证失败
