Cast+Select from pl/sql table question

Hi Gurus !

Is there any way to use "select" on PL/SQL tables? I tried it the way below but is doesn't work. What's wrong?

CREATE OR REPLACE PROCEDURE TESTPROC IS
    Type T_REC is record (AN NUMBER, B Varchar2(1));     Type test is table of T_REC;

    V_TEST TEST;
    V_NUM NUMBER;
BEGIN
    select CAST(V_TEST.AN as NUMBER) into V_NUM from table(v_test); END TESTPROC; Received on Thu Jan 25 2001 - 05:55:23 CST
