使用select查询在plsql中创建记录

Question

可能是一个非常简单的问题，但我创建了一个包含3列的记录。第三列我将在稍后分配一个值。查询为记录选择2列。我错过了什么？抛出的错误是有太多的值＆＃34;在我的选择陈述中。

create or replace Procedure Pledges3 
(IDdonor In Int, flag Out Varchar)
as 
type allPledges is record(iddonor dd_pledge.iddonor%type, idstatus dd_status.idstatus%type, flag Varchar(25));
allPledges2 allpledges;
Begin
Select dd_pledge.iddonor, dd_status.idstatus 
  into allpledges2 
    from dd_donor
      join dd_pledge on dd_donor.iddonor=dd_pledge.iddonor
        join dd_status on dd_pledge.idstatus=dd_status.idstatus
          where dd_pledge.IDdonor=305;
    if allpledges2.idstatus = '10' THEN 
     Flag := 'True';
      elsif allpledges2.idstatus= '20' THEN 
        Flag := 'False';
    End if;
    dbms_output.put_line(flag);
End;

检查以下代码，更正：

create or replace Procedure Pledges3 
(IDdonor In Int, flag Out Varchar)
as 
type allPledges is record(iddonor dd_pledge.iddonor%type, idstatus dd_status.idstatus%type, flag Varchar(25));
allPledges2 allpledges;
Begin
Select dd_pledge.iddonor, dd_status.idstatus, null 
  into allpledges2 
    from dd_donor
      join dd_pledge on dd_donor.iddonor=dd_pledge.iddonor
        join dd_status on dd_pledge.idstatus=dd_status.idstatus
          where dd_pledge.IDdonor=305;
    if allpledges2.idstatus = '10' THEN 
     allPledges2.Flag := 'True';
      elsif allpledges2.idstatus= '20' THEN 
        allPledges2.Flag := 'False';
    End if;
    dbms_output.put_line(allPledges2.flag);
End;
