ORA-00604在plsql或应用程序中提交事务时

Question

我有organization表，其结构如下：

create table organization (
    id number(10) not null,
    parent_id number(10),
    title varchar2(255 char),
    hierarchy_code varchar2(255 char)
);
alter table organization
  add constraint fk_parent_id foreign key (parent_id)
  references organization (id);

具有名为hierarchy_code的列，其中包含每个组织的层次结构代码，例如，如果我们具有以下组织：

  department A
  |
  |__ office 1
  |   |
  |   |__ room A
  |   |   |__ room A1
  |   |   |__ room A2
  |   |
  |   |__ room B

此表的记录如下：

 ________________________________________________
| id | parent_id | title        | hierarchy_code |
|-------------------------------------------------
| 1  | null      | department A | 1              |
|-------------------------------------------------
| 2  | 1         | office 1     | 1001           |
|-------------------------------------------------
| 3  | 2         | room A       | 1001001        |
|-------------------------------------------------
| 3  | 3         | room A1      | 1001001001     |
|-------------------------------------------------
| 4  | 3         | room A2      | 1001001002     |
|-------------------------------------------------
| 5  | 2         | room B       | 1001002        |
 ------------------------------------------------

我通过以下过程生成hierarchy_code的值：

create or replace procedure after_save_organization(id_var       number, old_parentid number, new_parentid number) is
  old_hierarchy_code        varchar2(255 char);
  new_hierarchy_code        varchar2(255 char);
  parent_new_hierarchy_code varchar2(255 char);
  sub_str1                  varchar2(255 char);
  str1                      varchar2(255 char);
  number_                   number(10);
begin

  select p.hierarchy_code
    into old_hierarchy_code
    from organization p
   where p.id = id_var;

  select hierarchy_code
    into parent_new_hierarchy_code
    from organization
   where id = new_parentid;

  select max(p.hierarchy_code)
    into str1
    from organization p
   where p.parentid = new_parentid
     and p.hierarchy_code != old_hierarchy_code;

  if str1 is not null then
    sub_str1 := substr(str1, 0, length(str1) - 3);

    number_           := to_number(substr(str1,
                                          length(str1) - 2,
                                          length(str1)));
    number_           := number_ + 1;
    new_hierarchy_code := sub_str1 || case
                           when length(number_) = 1 then
                            '00'
                           when length(number_) = 2 then
                            '0'
                         end || number_;
  else
    new_hierarchy_code := parent_new_hierarchy_code || '001';
  end if;

  update organization po
     set po.hierarchy_code = new_hierarchy_code ||
                            substr(po.hierarchy_code,
                                   length(old_hierarchy_code) + 1,
                                   length(po.hierarchy_code))
   where exists (select pp.id
            from organization pp
           where po.id = pp.id
          connect by prior pp.id = pp.parentid
           start with pp.id = id_var);
end;

一切正常，但是对于自定义组织，更改parent_id后，调用过程以重新生成层次结构代码时，过程完全执行，但是当要提交更改时，出现此错误：
