不能实例化一个type ，求请教

create or replace PACKAGE pkType
ASTYPE arrayNum IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;END pkType;create or replace function sfRtCC0100_SCB
(
  l_no             IN  NUMBER,
  l_id            IN  VARCHAR2,
  l_cc          OUT NUMBER,
  l_aaNoArray       OUT pkType.arrayNum
) RETURN INTEGER
IS
BEGIN
     l_cc  := 12;
     l_aaNoArray := new pkType.arrayNum();   -- 这边报PLS-00222错误
END;
