连续创建多个Oracle触发器失败，单个创建才成功的解决方法

当用到自增序列，需要用到触发器的时候，当我连续执行创建多个触发器时，总是报编译通过，但存在警告或错误。

---.应用信息
drop table app_info cascade constraints;
create table APP_INFO
(
  id      NUMBER()   not null,
  appid    VARCHAR2()        default NULL,
  appkey    VARCHAR2()       default NULL,
  md5_key          VARCHAR2()    default NULL,
  aes_key    VARCHAR2()      default NULL,
  permission    VARCHAR2()     default NULL,
  email    VARCHAR2()       default NULL,
  password    VARCHAR2()      default NULL,
  ras_public_key     VARCHAR2()  default NULL,
  constraint APP_INFO primary key (id)
);

drop sequence app_info_id;
create sequence app_info_id
increment by
start with
nomaxvalue
nominvalue
nocache;

CREATE OR REPLACE TRIGGER addAppInfo BEFORE INSERT ON App_INFO FOR EACH ROW
 BEGIN
    SELECT app_info_id.nextval INTO :new.id  FROM dual;
 END; 

---.unit信息
drop table unit_info cascade constraints;
create table UNIT_INFO
(
  UNIT_ID        NUMBER()  not null,
  USERID          VARCHAR2()        default NULL,
  UNIT_NAME      VARCHAR2()        default NULL,
  UNIT_LINKMAN      VARCHAR2()    default NULL,
  ORGANIZATION_CODE        VARCHAR2()     default NULL,
  constraint UNIT_INFO primary key (UNIT_ID)
);

drop sequence unit_info_id;
create sequence unit_info_id
increment by
start with
nomaxvalue
nominvalue
nocache;

CREATE OR REPLACE TRIGGER addUnitInfo BEFORE INSERT ON UNIT_INFO FOR EACH ROW
 BEGIN
    SELECT unit_info_id.nextval INTO :new.unit_id  FROM dual;
 END; 

错误截图如下：

这种创建是失败的，因为触发器需要先编译，每创建一个触发器，需要以“/”结束，然后才能执行下一个。

正确的做法应该是这样的;

 注意：存储过程也是一样的。
