nested tables in SQL Profiler

I am getting insufficient privileges when running this sql that has a nested table in it.

Can you help me? Thank you.
**************************************
SELECT *
FROM (SELECT KEY_ID,

MAX (DECODE (n.name, 'volume.break', n.value, null)) "volume.break",

MAX (DECODE (n.name, 'SEGMENT_UUID', n.value, null)) "SEGMENT_UUID"

FROM metadata_tab t, TABLE(t.md_ntab) n

WHERE KEY_ID IN (SELECT KEY_ID

FROM metadata_tab T, TABLE(T.md_ntab) N

WHERE T.key_context = 'PRI' AND

T.grouping = 'Element Metadata' AND

N.name = 'PUB_CODE' AND N.value = 'FLLB'

) AND

name IN ('volume.break', 'SEGMENT_UUID')
GROUP BY KEY_ID)
WHERE "volume.break" IS NOT NULL

Does it work in SQL*Plus?
