ORA - 00933 与内部连接和“as"混淆

问题描述

我有一个使用 inner join 从两个表中获取数据的查询，但我收到错误 SQL 命令未正确结束，as"下有一个星号:

I have this query of getting data from two tables using an inner join, but I get the error SQL command not properly ended with an asterix under "as":

select P.carrier_id, O.order_id, O.aircraft_id, O.quantity

from orderline AS O

inner join purchaseorder AS P

on O.order_id = P.carrier_id;

the error:

from orderline AS O ( with an asterix under AS)


Error at line 2
Ora-00933: SQL command not properly ended.

关于这一点，我认为 AS 不会成为问题，因为它只是引用了一个别名，但我很困惑为什么会出现这种情况.

In regards to this I thought that AS wouldn't be an issue as it's just referencing an alias, but I'm so confused as to why this is coming up.

推荐答案

去掉AS关键字

select 
   P.carrier_id, 
   O.order_id, 
   O.aircraft_id, 
   O.quantity
from 
   orderline O
inner join purchaseorder P
   on O.order_id = P.carrier_id;
