Question

The following query displays all free time slots for a specific which haven’t been booked:-

 SELECT DISTINCT tbl_available.timeslot
FROM            tbl_appointment RIGHT JOIN
                     tbl_available ON (tbl_appointment.employeeID = tbl_available.employeeID) AND (tbl_appointment.apptTime = tbl_available.timeslot)
WHERE        tbl_appointment.apptTime IS NULL
ORDER BY 1;

This is fine but I’m trying to get it so that it runs this query based on any date which is passed in as a parameter using c#. (I only need help with the SQL side of things)

Using the following tables:-

 Appointment:-      Availability:-
 apptTime           timeSlot
 apptDate           DoctorId
 patientID

Any suggestions would be greatly appreciated.
