Question

这是我的查询，因为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上不支持它，就像在select列上一样

在oracle 009933 sql命令中获取错误未正确结束
