选择 Distinct 和 Inner Join 带来重复的值

我在使用内部联接从两个表中获取唯一值时遇到问题。

SELECT distinct cast (opd.order_number as integer), p.payment_id ,\n    pt.transaction_status, \n    opd.installments_number, \n    pt.amount, \n    pt.origin_amount,\n    p.payment_capture_type,\n    opd.brand,\n    pt.created_date, \n    d."name" \nFROM payment p \nINNER JOIN payment_transaction pt ON pt.payment_id = p.payment_id\ninner join "domain" d on d.domain_id = p.domain_id \nINNER JOIN attempted_online_payment_data opd ON p.payment_id = CAST ( opd.order_number AS INTEGER )\nWHERE \np.created_date >= \'2021-11-01\' and status = 1\n

这是我正在使用的查询，我想要一个 payment_id\xc2\xb4s 的唯一值列表，但是当我这样做时，由于某种原因它会带来两个相同的 payment_id。
