SQL & PL/SQL :: Table Type Of RECORD In A Query?

I am in the need of using a table type object in SQL query.

I have a package which has a spec in which I have declared :

TYPE TESTREC IS RECORD
(
RE_ID NUMBER(9),
RATING_TARIFF_NAME VARCHAR2(40),
);
TYPE TESTTABTYPE IS TABLE OF TESTREC;
TTR TESTTABTYPE;

In one of the package procedures I am collecting data into the above indicated table type object (TTR):

SELECT
RE_ID,
RATING_TARIFF_NAME
BULK COLLECT INTO TTR
FROM TESTPACKTAB;

This works fine. The values get collected into TTR and am able to print them too.

But when I :

SELECT
AA.RATING_TARIFF_NAME
INTO v_name
FROM
TABLE( TTR ) AA ;

in the same procedure immediately after the collection I get the error while running the procedure :

ORA-21700 : Object does not exist or is marked for delete.
