我正在 oracle fusion 云中创建新的数据模型。我有不同的表，我想链接所有 3 个表。我应该怎么办？以下是我使用的表格：
doo_headers_all dha,
ra_terms rt,
ra_customer_trx_all rcta,
hz_cust_site_uses_all bill_hcsua,
hz_cust_acct_sites_all bill_hcasa,
hz_cust_accounts bill_hca,
hz_party_sites bill_hps,
hz_parties bill_hp,
hz_party_site_uses ship_hpsu,
hz_party_sites ship_hps,
hz_parties ship_hp,
hz_addtnl_party_names bill_hapn,
hz_addtnl_party_names ship_hapn
我链接了除 DOO_HEADERS_ALL 之外的所有这些，我试图搜索我可以使用哪些外键，以便我可以链接它们，但我没有看到任何答案。
rcta.term_id = rt.term_id(+)
and rcta.bill_to_site_use_id = bill_hcsua.site_use_id(+)
and bill_hcsua.cust_acct_site_id = bill_hcasa.cust_acct_site_id(+)
and bill_hcasa.cust_account_id = bill_hca.cust_account_id(+)
and bill_hcasa.party_site_id = bill_hps.party_site_id(+)
and bill_hps.party_id = bill_hp.party_id(+)
and rcta.ship_to_party_site_use_id = ship_hpsu.party_site_use_id(+)
and ship_hpsu.party_site_id = ship_hps.party_site_id(+)
and ship_hps.party_id = ship_hp.party_id(+)
and bill_hp.party_id = bill_hapn.party_id(+) and bill_hapn.party_name_type (+) = 'PHONETIC'
and ship_hp.party_id = ship_hapn.party_id(+) and ship_hapn.party_name_type (+) = 'PHONETIC'
这是我用来链接除 doo_headers_all 之外的其他表的
