将数据传递到另一个集合对象（oracle）中的集合

我已创建一个集合，用于传递数据并在过程中使用：

Create or Replace type Search_Type AS Object(
ID Number(38),
SF_ID Varchar(25),
PF_ID Varchar(25),
C_ID SYS.ODCIVARCHAR2LIST
);

Create or Replace Type  Search_Array AS Table of Search_Type;

我调用的过程如下：

SET SERVEROUTPUT ON  
DECLARE
    v_S_ID     Search_Array;
    v_C_ID     SYS.ODCIVARCHAR2LIST;
BEGIN
v_S_ID := Search_Array();
v_O_ID := SYS.ODCIVARCHAR2LIST();
v_O_ID.Extend(2);
v_O_ID(1) := '4';
v_O_ID(2) := '5';
v_S_ID.EXTEND(4);
v_S_ID(1) := Search_Type(1,'2','3',v_C_ID);

FOR i IN v_S_ID.first..v_S_ID.last LOOP dbms_output.put_line(--'Iteration: '
                                                                          --   || i ||
                                                                             v_S_ID(i).id
                                                                             || ', '
                                                                             || v_S_ID(i).SF_ID
                                                                             || ', '
                                                                             || v_S_ID(i).PF_ID
                                                                             || ', '
                                                                             || v_S_ID(i).C_ID.count);
                END LOOP;

END;

我得到以下错误：

Error report -
ORA-06531: Reference to uninitialized collection
ORA-06512: at line 17
06531. 00000 -  "Reference to uninitialized collection"
*Cause:    An element or member function of a nested table or varray
           was referenced (where an initialized collection is needed)
           without the collection having been initialized.
*Action:   Initialize the collection with an appropriate constructor
           or whole-object assignment.
