Nepoužívejte asociativní pole definovaná v rozsahu PL/SQL (tj. v balíčku), místo toho používejte kolekci definovanou v rozsahu SQL.
create or replace TYPE stringlist IS TABLE OF VARCHAR2(4000);

Pak je balíček:
CREATE OR REPLACE PACKAGE mypackage
AS
PROCEDURE table_in_table_out(
inputArray IN stringlist,
outputArray OUT stringlist2,
resultString OUT VARCHAR2
);
END mypackage;
/
CREATE OR REPLACE PACKAGE BODY mypackage
AS
PROCEDURE table_in_table_out(
inputArray IN stringlist,
outputArray OUT stringlist2,
resultString OUT VARCHAR2
)
IS
i BINARY_INTEGER;
BEGIN
IF inputArray IS NULL THEN
RETURN;
END IF;
outputArray := stringlist2();
IF inputArray IS EMPTY THEN
RETURN;
END IF;
-- Handle sparse arrays
i := inputArray.FIRST;
LOOP
outputArray.EXTEND;
outputArray(outputArray.LAST) := inputArray(i);
resultString := resultString || inputArray(i);
EXIT WHEN i = inputArray.LAST;
i := inputArray.NEXT(i);
END LOOP;
END;
END mypackage;

Testování v databázi :
SET SERVEROUTPUT ON;
DECLARE
i stringList := StringList( 'A', 'C', 'F' );
e stringlist2;
s VARCHAR2(4000);
n BINARY_INTEGER;
BEGIN
i.DELETE(2);
n := i.FIRST;
LOOP
DBMS_OUTPUT.PUT_LINE( n || ': ' || i(n) );
EXIT WHEN n = i.LAST;
n := i.NEXT(n);
END LOOP;
mypackage.table_in_table_out( i, e, s );
DBMS_OUTPUT.PUT_LINE( s );
n := e.FIRST;
LOOP
DBMS_OUTPUT.PUT_LINE( n || ': ' || e(n) );
EXIT WHEN n = e.LAST;
n := e.NEXT(n);
