Mysql 具有多列子查询的SQL cartesion产品，未知列问题

问题：on条款中的未知列daf.id

---

我有这个专栏，但它仍然是说未知的专栏。请帮忙

我相信mySQL可以根据字段别名进行订购

SELECT 
   daf.id as affiliate_id,
   daf.name as affiliate_name,
   dal.name as allocation_name,
   dal.id as allocation_id,
   dal.allocation,dal.price
FROM 
     degreeamerica.affiliates daf, degreeamerica.allocations dal
JOIN 
     (select pap.lead_price,pap.live, pap.allocation_id,pap.affiliate_id from paul.affiliates_price pap) pafp  
ON (dal.id=pafp.allocation_id and daf.id=pafp.affiliate_id) 
ORDER BY daf.id;

你能不能也包括相关的表格，这样错误就可以重现？你需要模式吗？

ORDER BY affiliate_id;
