如何在Oracle存储过程中正确使用对象类型？

Question

我有这种类型的定义：

Create Type "T1" as Table of Varchar2(10);/ 

这得到了执行。

如何在PL/SQL中使用T1类型变量？我有以下步骤：

Create or replace PROCEDURE P1 
AS 
    P_K T1; 
BEGIN 
    SELECT P_K_J INTO P_K FROM SOME_TABLE WHERE NAME='JONES' ; 
    FOR I IN P_K.FIRST..P_K.LAST LOOP 
    DBMS_OUTPUT.PUT_LINE('THE VALUES OF P_K ARE' || P_K(I)); 
    END LOOP; 
END P1; 

这提供了以下错误：

 
ERROR: 
3/5  PL/SQL: Item ignored 
3/5  PLS-00311: the declaration of "T1" is incomplete or malformed 

我的问题是：如何实例类型的变量T1
