Question

以下のクエリにアウター・ジョインを追加する必要があります。

は、これまでのところ私は

select local_code from HSBC_LOCAL_INVOL_PARTY 
h join t_cdr T2 
on T2.counterparty_new = h.entity_code 

を追加しようとしましたが、それは動作しません。最後に明示的な外部結合が必要です。助けてください

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
