我的光标:
SELECT xzis.msisdn msisdn, xzis.in_account_number in_Account_number
FROM xxobw_zte_in_sync xzis
WHERE NOT EXISTS
(SELECT 1
FROM hz_contact_points hcp, hz_cust_Accounts hca
WHERE hcp.owner_table_id = hca.party_id
AND hcp.owner_table_name = 'HZ_PARTIES'
AND HCP.PHONE_NUMBER =
SUBSTR (xzis.msisdn, -8)
AND NVL (hca.attribute12, 'NIL') =
xzis.in_account_number);
我已为所有列提供别名,但仍面临问题。有什么建议么?
