Необходимо использовать LATERAL (inline-представление), как посоветовал
Максим Y
Но, до версии 12С это было типа недокументированной "фичей" и чтобы ее включить необходимо выполнить:
alter session set events '22829 trace name context forever';
Попробовал в 11g (на dbfiddle.uk) и сработало!

PS: попробовал у себя на 9i и.... тоже сработало! ))
alter session set events '22829 trace name context forever';
WITH
test AS (
SELECT 'проул.' as code, 'проул.|пр-к|' as str FROM dual UNION
SELECT 'ул.' as code, 'ул.|улица|ул-ца|' as str FROM dual UNION
SELECT 'пер.' as code, 'пер.|переулок|' as str FROM dual UNION
SELECT 'кв-л' as code, 'кв-л|квартал|' as str FROM dual UNION

SELECT t1.code, SUBSTR(t1.str,
DECODE(t2.lvl, 1, 1, INSTR(t1.str, '|', 1, t2.lvl - 1) + 1),
INSTR(t1.str, '|', 1, t2.lvl)
- DECODE(t2.lvl, 1, 1, INSTR(t1.str, '|', 1, t2.lvl - 1) + 1))
FROM test t1,
LATERAL (SELECT level AS lvl FROM dual
CONNECT BY NVL(INSTR(t1.str, '|', 1, level), 0) > 0) t2
;
так же есть еще вариант, через преобразование в XML:
WITH
str_csv AS (
SELECT 'проул.' as code, 'проул.|пр-к|' as str FROM dual UNION
SELECT 'ул.' as code, 'ул.|улица|ул-ца|' as str FROM dual UNION
SELECT 'пер.' as code, 'пер.|переулок|' as str FROM dual UNION

SELECT 'линия' as code, 'линия|' as str FROM dual UNION
SELECT 'парк' as code, 'парк|' as str FROM dual UNION
SELECT 'рзд' as code, 'рзд|разъезд|' as str FROM dual UNION
SELECT 'сад' as code, 'Сад|' as str FROM dual UNION
SELECT 'тракт' as code, 'тракт|' as str FROM dual UNION
SELECT 'тер' as code, 'тер|территория|' as str FROM dual UNION
SELECT 'ст' as code, 'ст|станция|' as str FROM dual UNION
SELECT 'сл' as code, 'сл|слобода|' as str FROM dual UNION
SELECT 'пр-кт' as code, 'пр.|проспект|пр-кт|' as str FROM dual UNION
SELECT 'шоссе' as code, 'ш.|шоссе|' as str FROM dual UNION
SELECT 'пл' as code, 'пл|площадь|пл-дь|' as str FROM dual UNION
SELECT 'наб.' as code, 'наб.|набережная|наб-ая|' as str FROM dual UNION
SELECT 'тупик' as code, 'тупик|' as str FROM dual UNION
SELECT 'мост' as code, 'мост|' as str FROM dual UNION
SELECT 'пр.' as code, 'проезд|пр.|' as str FROM dual UNION
SELECT 'блв.' as code, 'блв.|бульвар|' as str FROM dual UNION
SELECT 'мкн.' as code, 'мкн.|микрорайон|' as str FROM dual UNION
SELECT 'пос.' as code, 'пос.|посёлок|' as str FROM dual UNION
SELECT 'овраг' as code, 'овраг|' as str FROM dual UNION
SELECT 'городок' as code, 'городок|' as str FROM dual
),
str_xml AS (
SELECT code, XMLType('<a><b>'||replace(str, '|','</b><b>')||'</b></a>') xml FROM str_csv
)
SELECT
code, extractValue(value(t),'b') str_type
FROM
str_xml s,
TABLE(XMLSequence(s.xml.extract('a/b'))) t
WHERE extractValue(value(t),'b') is not null
;
