Oracle is giving me an error (ORA-00907: missing right parenthesis) when I run this query:
select * from reason_for_appointment where reason_for_appointment_id in ( select reason_for_appointment_id from appointment_reason where appointment_id = 11 order by appointment_reason_id )
However, when I run just the subquery, there’s no error.
Can anyone explain what the problem is?
The problem is that ORDER BY is not permiited inside a subquery like this one. Why did you want to have one?
