我正在尝试在嵌套表中插入引用，但我一直收到错误SQL错误：ORA-00936：缺少表达式

相关类型和表格如下：

create type TP1_PROPRIETE as object (
  NO_PROPRIETE number(10),
  ADRESSE_PRO varchar2(20),
  VILLE_PRO varchar2(20),
  NB_PIECES_PRO number(2));
/

create type TP1_CAPROPRO as object (
  REF_PROPRIETE_CAPROPRO ref TP1_PROPRIETE);
/

create type TP1_CAPROPRO_NT as table of TP1_CAPROPRO;
/

create type TP1_PARTENAIRE as object (
  NOM_COMPLET_PAR varchar2(40));
/

create type TP1_PARTENAIRE_NT as table of TP1_PARTENAIRE;
/

create type TP1_PROPRIETAIRE as object (
  NO_PROPRIETAIRE number(10),
  NOM_COMPLET_PROR varchar2(40),
  REF_PARTENAIRES_PROR TP1_PARTENAIRE_NT,
  REF_PROPRIETES_PROR TP1_CAPROPRO_NT);
/

create table TP1_PROPRIETAIRE_T of TP1_PROPRIETAIRE
  nested table REF_PARTENAIRES_PROR store as TP1_PARTENAIRE_NT_PROR
  nested table REF_PROPRIETES_PROR store as TP1_CAPROPRO_NT_PROR;
/

create table TP1_PROPRIETE_T of TP1_PROPRIETE (
  constraint CT_NB_PIECES_NON_NEG check (NB_PIECES_PRO > 0));
/

以下是插页：

insert into TP1_PROPRIETE_T
  values(1465798654,
         '1170 Victory',
         'New York',
         5);
/

insert into TP1_PROPRIETAIRE_T
  values(9654255475,
         'Mike Ross',
         TP1_PARTENAIRE_NT(TP1_PARTENAIRE('Andre Ross')),
         TP1_CAPROPRO_NT(TP1_CAPROPRO(select ref(p)
                                        from TP1_PROPRIETE_T p
                                        where p.NO_PROPRIETE = 1465798654)));
/

执行最后一次插入时出现以下错误：

Error starting at line 117 in command: insert into TP1_PROPRIETAIRE_T 
 values(9654255475,
          'Mike Ross',
          TP1_PARTENAIRE_NT(TP1_PARTENAIRE('Andre Ross')),
          TP1_CAPROPRO_NT(TP1_CAPROPRO(select ref(p)
                                         from TP1_PROPRIETE_T p
                                         where p.NO_PROPRIETE = 1465798654)))
 Error at Command Line:121 Column:39
 Error report: SQL
 Error: ORA-00936: missing expression
 00936. 00000 -  "missing expression"
 *Cause:    
 *Action:

根据我从SO和其他论坛上读到的内容，错误最有可能出现在最后一个选择ref（p）...但语法对我来说似乎很好，所以我真的不知道为什么我得到这个错误。谢谢你的时间。

我会使用insert . . . select（个人偏好），但问题是子查询缺少额外的括号：

insert into TP1_PROPRIETAIRE_T
    select 9654255475, 'Mike Ross',
           TP1_PARTENAIRE_NT(TP1_PARTENAIRE('Andre Ross')),
           TP1_CAPROPRO_NT(TP1_CAPROPRO( (select ref(p)
                                          from TP1_PROPRIETE_T p
                                          where p.NO_PROPRIETE = 1465798654
                                         )
                                       ))
    from dual;
