sql - oracle 009933 sql 命令未正确结束

Question

这是我的查询，我不明白为什么它不起作用。

  select o.MFR, o.PRODUCT, c.company, p.PRICE 
    from ORDERS AS o 
    inner join customers AS c on c.CUST_NUM = o.CUST
    inner join PRODUCTS AS p On p.MFR_ID = o.MFR 
    where o.CUST in ('2111','2112','2105','2119') and o.AMOUNT < '3000' 
    order by c.company DESC;

Answer 1

从别名中删除

select o.MFR, o.PRODUCT, c.company, p.PRICE 
from ORDERS  o 
inner join customers  c on c.CUST_NUM = o.CUST
inner join PRODUCTS  p On p.MFR_ID = o.MFR 
where o.CUST in ('2111','2112','2105','2119') and o.AMOUNT < '3000' 
order by c.company DESC;

oracle 在 FROM 中不支持它支持的选择列
