sql - ORA - 00933 confusion with inner join and "as"

Question

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.

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.

Answer 1

You are not allowed to insert keyword as between table name and its alias.
