Question

我有这种类型的定义：

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

这已经执行了。

如何在PL / SQL中使用T1类型变量？我有以下程序：

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;

这会出现以下错误：

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

我的问题是：如何实例化T1
