Question

我有这样的对象和方法：

create or replace type PolicyType as object(
policy_id number,
policy_nr varchar2(20),
price number) NOT FINAL;
/
create or replace type TravelerType as object(
first_name varchar2(30),
last_name varchar2(30),
pers_code varchar2(12));
/
create or replace type TravelersType as table of TravelerType;
/
create or replace type ref_TargetPlaceType as object (
target_code varchar2(4),
description varchar2(30));
/
create or replace type TravelPolicyType under PolicyType ( 
target_code REF ref_TargetPlaceType,
traveler_data TravelersType,
MEMBER FUNCTION getTraveler (p_code IN varchar2) RETURN TravelerType,
MEMBER PROCEDURE addTraveler( traveler IN TravelerType ));
/
CREATE OR REPLACE TYPE BODY TravelPolicyType  AS
MEMBER FUNCTION getTraveler(p_code IN varchar2) RETURN TravelerType AS
  BEGIN
  for i in 1 .. self.traveler_data.count() loop
  if( self.traveler_data(i).pers_code = p_code )
  then
  return self.traveler_data(i);
  end if;
  end loop;
END;
MEMBER PROCEDURE addTraveler(traveler IN TravelerType) AS
BEGIN
 self.traveler_data.extend();
 self.traveler_data(self.traveler_data.count) :=traveler;
END;
END;

我想调用方法，我敢打赌两者都会出错 ORA-04063: 类型正文“SQL_LPZCXWDSKRAXJUEWPMXNUMWYH.TRAVELPOLICYTYPE”有错误 ORA-06512:

declare 
    policy_d TravelPolicyType;
    traveler TravelerType;
  
begin  
    select value(a) into policy_d from travel_policies a where a.policy_nr='TP00000000003';
    traveler:=policy_d.getTraveler('050976-12568');
end;


declare 
    policy_d TravelPolicyType;
    new_traveler TravelerType;
    
begin  
   select value(a) into policy_d from travel_policies a where a.policy_nr='TP00000000003';
   new_traveler:=TravelerType('Test','Traveler', '123456-44444');
   policy_d.addTraveler(new_traveler);
end;

无法理解我做错了什么。请帮忙指教

查看该对象中报告了哪些错误：

select * from user_errors;

NAME	TYPE	SEQUENCE	LINE	POSITION	TEXT	ATTRIBUTE	MESSAGE_NUMBER
TRAVELPOLICYTYPE	TYPE BODY	1	4	22	PLS-00302: component 'TRAVELERS_DATA' must be declared	ERROR	302
TRAVELPOLICYTYPE	TYPE BODY	2	4	3	PL/SQL: Statement ignored	ERROR	0

您的类型有traveler_data，但正文指的是travelers_data。您需要使该命名保持一致。
