Inner join within an Inner join

Good afternoon, I'm just looking for an explanation - quick or otherwise - for what this syntax actually means.


(dbo_Appointment INNER JOIN dbo_MPI ON dbo_Appointment .Patient = dbo_MPI.Patient) INNER JOIN dbo_Referrals ON dbo_Appointment .Referral_Ref = dbo_Referrals .Referral_Ref

Many thanks,

RE: Inner join within an Inner join


Same as


, dbo_MPI 
, dbo_Referrals 
WHERE dbo_Appointment .Patient      = dbo_MPI.Patient
  and dbo_Appointment .Referral_Ref = dbo_Referrals .Referral_Ref 

RE: Inner join within an Inner join

Hi Skip, thanks for that. Yes, I guess that makes sense as graphically there are joined that way.

Now, this seems similar but different:


dbo_AR_DateLookUp RIGHT JOIN (dbo_AR_ClinicCodes RIGHT JOIN dbo_CDI_OP_Appointment ON dbo_AR_ClinicCodes.Local_Clinic_Code = dbo_CDI_OP_Appointment.Clinic_Or_Facility_Code) ON dbo_AR_DateLookUp.Source_Date = dbo_CDI_OP_Appointment.Appointment_Date

dbo_AR_DateLookUp is Right joined on Source_Date to dbo_CDI_OP_Appointment. Appointment_Date


dbo_AR_ClinicCodes. Local_Clinic_Code is Right joined ON dbo_CDI_OP_Appointment. Clinic_Or_Facility_Code

Is this just how it looks when there are two tables joined to one common table?

Many thanks,
