SQL need to add outerjoin to the query below - sql

Question

In the below SQL:
I need to add two columns in the result
1) Local_code
2)Local_CPTY_SYS_ID,
which are in HSBC_LOCAL_INVOL_PARTY table.
So far I have tried to add
select local_code from HSBC_LOCAL_INVOL_PARTY
h join t_cdr T2
on T2.counterparty_new = h.entity_code
but that doesn't work. It needs an explicit outer join in the end. Please help
SELECT
T2.counterparty_new,
T2.bis_entity_type_original,
T2.counterparty_new_desc,
T2.counterparty_new_attribute_6,
T2.method_original,
T2.netting_agreement_reference,
T2.internal_rating_new,
T2.counterparty_type_original,
T2.obligor_grade_new,
T2.pd_pre_floor_new,
T2.pd_new,
T2.lgd,
T2.rwa
from t_cdr T2,
(
SELECT * FROM (
SELECT
FINAL.FILTER_MARKER,
FINAL.entity_code
FROM (
SELECT
FILTER_POP.entity_code,
FILTER_POP.FILTER_MARKER
FROM (
SELECT
CASE
WHEN CONCAT(Dlgd,unfloored_lgd) IS NOT NULL
THEN 'EXCLUDE'
WHEN CONCAT(Dlgd,unfloored_lgd) IS NULL
THEN 'INCLUDE'
END AS FILTER_MARKER,
entity_code,
Dlgd,
unfloored_lgd
FROM
HSBC_LOCAL_INVOL_PARTY
WHERE
((HSBC_LOCAL_INVOL_PARTY.entity_code) NOT LIKE '%DUM%')
AND
((HSBC_LOCAL_INVOL_PARTY.entity_code) NOT LIKE '%HSBC%')
) FILTER_POP
GROUP BY
FILTER_POP.entity_code,
FILTER_POP.FILTER_MARKER) FINAL
GROUP BY
FINAL.FILTER_MARKER,
FINAL.entity_code
ORDER BY
FINAL.entity_code)
PIVOT
(
COUNT(FILTER_MARKER)
FOR FILTER_MARKER IN ('INCLUDE' AS INCLUDE,'EXCLUDE' AS EXCLUDE)
)
WHERE INCLUDE = 1 AND EXCLUDE = 0
) ENTITY_FILTER
WHERE ENTITY_FILTER.entity_code = T2.counterparty_new
AND T2.method_original = 'ADV'
ORDER BY T2.rwa DESC

Solved it: Look at the last few lines. Took a while but optimized it as well for performance.
