Question

Hey there I am trying to learn SQL by trying to complete online questions and I’m trying to create a view.

I have created a SELECT query that works and now trying to turn it into a view, though when following the online instructions and enter the script that should create a view I come up with the duplicate field error.

I’ve looked into it and it may be “doctor.fullname” as a duplicate field but this is from another table. Andway I have deleted and still tried it but the error still appears.
I know there is probably an easy solution and sorry to bother you with this but it will be must appreciated.

CREATE VIEW patient_registration_form
AS
SELECT 
     patient.patient_id, 
     patient.nok_no,
     patient.f_name, 
     patient.s_name, 
     patient.sex, 
     patient.dob, 
     patient.marital_status, 
     patient.date_registered, 
     nok.tel_no, 
     nok.full_name, 
     nok.address, 
     nok.relationship, 
     doctor.doctor_id,
     doctor.clinic_no, 
     doctor.full_name, 
     doctor.address
FROM doctor, patient, nok
WHERE doctor.doctor_id = patient.doctor_id
AND nok.nok_no = patient.nok_no;

Answer 1

You have two full_name listed… one for nok.full_name and one for doctor.full_name. One needs to be renamed such as nok.full_name as nok_full_name.
