Question

I have two tables Profile_Appointments and Profile.

Each record in the profile table has a Profile_key and a Profile_Type_Key in addition to other profile data – first name, last name, etc.

Rep’s have Profile_Type 4, Customer’s have Profile_Type 6

 PROFILE TABLE
 Profile_Key    Profile_Type_key    First_Name     Last_Name
  1234                 4              John            Smith
  8765                 6              Mike            Jones

The Profile_Appointment table holds two records for each appointment one with the Rep’s
Profile_Key the other with the customer’s Profile_Key

 Appointment_Key        Profile_Key     
     10                    1234
     10                    8765                  

The appointment_key refers to the Appointment table.

I need make a query that results in one record for each appointment and has both the rep and customer’s data from the Profile table

 THE RESULT I WANT
 Appointment_Key  Profile_Key Rep    Profile_Key Customer
    10                1234                    8765

This is the query that’s not working…

  select appointment_key, p.profile_key as Rep, p2.profile_key as Customer, p.firs_name,p2.first_name from profile_appointment pa

  join profile p 
  on p.profile_key = pa.profile_key

  join profile p2
  on p2.profile_key = pa.profile_key

  where p.profile_type_key = '4' or p2.profile_type_key = '6' 

What I get is:

 Appointment_Key      Rep      Customer     Rep      Customer
    10                1234      1234        John       John

I can’t figure out what I’m missing.
Thanks.

You need to satisfy both conditions so you need AND instead of OR

    select pa.appointment_key, p.profile_key as Rep, p2.profile_key as Customer, 
        p.first_name as RepName,p2.first_name as CustomerName
from profile_appointment pa    
join profile_appointment pa2 on pa.appointment_key = pa2.appointment_key
join profile p    on p.profile_key = pa.profile_key    and  p.profile_type_key = '4'
join profile p2   on p2.profile_key = pa2.profile_key   and  p2.profile_type_key = '6'
