我正在调用一个返回一种表类型的函数。

我的函数接收一个 varchar 类型的变量。因为我返回了我创建的类型，所以我必须进行强制转换和多重设置......
我的问题是，我的多重集中的选择在函数之外执行没有问题，但是当我执行我的函数时，它给了我 ORA-22814 属性或元素值大于类型错误中指定的值。注意：我总是使用相同的变量值运行脚本

类型对象：

create or replace
TYPE Z_PEDIDO_SeB IS OBJECT(
Contrato varchar2(4000 BYTE),
DataObjectivo date,
DataObjectivoSpecified date,
Descricao varchar2(500 BYTE),
DireccaoRequerente varchar2(50 BYTE),
Empresa varchar2(50 BYTE),
Estado varchar2(50 BYTE),
GestorDDS varchar2(100 BYTE),
GestorEncomenda varchar2(30 BYTE),
Referencia varchar2(50 BYTE),
Link varchar2(500 BYTE),
ObsComite varchar2(4000 BYTE),
OutrosFornecedores varchar2(4000 BYTE),
OutrosSistAfectados varchar2(4000 BYTE),
PrincipalSistAfectado varchar2(4000 BYTE),
Prioridade varchar2(50 BYTE),
Rede varchar2(50 BYTE),
Requerente varchar2(100 BYTE),
TestesAceitacao varchar2(10 BYTE),
proj_id varchar2(50 BYTE));

类型表：

create or replace
TYPE Z_TABLE_PEDIDO_SeB IS TABLE OF Z_PEDIDO_SeB;

功能：

create or replace
function Z_GetDadosCreateUpdate_SEB(
    proj_id in varchar2
)
return Z_TABLE_PEDIDO_SeB as
  t_dados   Z_TABLE_PEDIDO_SeB;
begin
  select

    ) 
      as Z_TABLE_PEDIDO_SeB)
    into
      t_dados
    from 
      dual;

  return t_dados;

end Z_GetDadosCreateUpdate_SEB;

我执行的是：

SELECT * FROM table (PVDEV.Z_GetDadosCreateUpdate_SEB('184765'));

我得到的错误：

ORA-22814: valor do atributo ou elemento é superior ao especificado no tipo
ORA-06512: na "PVDEV.Z_GETDADOSCREATEUPDATE_SEB", linha 7
22814. 00000 -  "attribute or element value is larger than specified in type"
*Cause:    Value provided for the object type attribute or collection element
       exceeded the size specified in the type declaration.
*Action:   Choose another value and retry the operation.

NOTE: if i try 18476 instead of 184765 it runs with no problem. So? how did i put such restriction? Where?
NOTE: Now i'm showing the error, the real one, i'm really sorry for the mistake

I would really appreciate any answer as other's people work is waiting for my part :S. Anyway thanks in advance for any information.

If I were you I would declared the function as the pipelined one and returned values by pipe row statement. And surely get rid of CAST/multiset. For loop statement is your choice. I'm sure it will work using my piece of advice.
