Question

I believe there is something wrong with my INSERT statement here. When I run my code, the error message shows:

Line: 5
Error: Sys.WebForms.PageRequestManagerServerErrorException: Incorrect syntax near ‘,’.

Is is something wrong in my where clause?

Here is my INSERT statement:

INSERT into AppointmentDetails (SelectedApptDate, SelectedApptStartTime, 
                                SelectedApptEndTime, SelectedWeddingPlanner) 
   SELECT 
       ApptID 
   from 
       Appointment 
   INNER JOIN 
       Appointment ON Appointment.ApptID = AppointmentDetails.ApptID 
   WHERE 
       SelectedApptDate = @SelectedApptDate, 
       SelectedApptStartTime = @SelectedApptStartTime, 
       SelectedApptEndTime = @SelectedApptEndTime, 
       SelectedWeddingPlanner = @SelectedWeddingPlanner

This is how I call it from C#:

    command.CommandText = "INSERT into AppointmentDetails (SelectedApptDate, SelectedApptStartTime, SelectedApptEndTime, SelectedWeddingPlanner) SELECT ApptID from Appointment INNER JOIN Appointment ON Appointment.ApptID = AppointmentDetails.ApptID WHERE SelectedApptDate = @SelectedApptDate, SelectedApptStartTime = @SelectedApptStartTime, SelectedApptEndTime = @SelectedApptEndTime, SelectedWeddingPlanner = @SelectedWeddingPlanner";

    command.Connection = connection;
    command.Parameters.AddWithValue("@SelectedApptDate", dateSelected);
    command.Parameters.AddWithValue("@SelectedApptStartTime", timeStart);
    command.Parameters.AddWithValue("@SelectedApptEndTime", timeEnd);
    command.Parameters.AddWithValue("@SelectedWeddingPlanner", weddingplanner);

Use AND instead of , to separate between the conditions in the WHERE clause. You have to write it this way:

INSERT into AppointmentDetails (SelectedApptDate, SelectedApptStartTime,
           SelectedApptEndTime, SelectedWeddingPlanner) 
SELECT ApptID 
from Appointment 
INNER JOIN Appointment ON Appointment.ApptID = AppointmentDetails.ApptID 
WHERE SelectedApptDate = @SelectedApptDate
   AND  SelectedApptStartTime = @SelectedApptStartTime
AND SelectedApptEndTime = @SelectedApptEndTime 
AND  SelectedWeddingPlanner = @SelectedWeddingPlanner";

However you will got a new exception after that, since you only select one column to insert into these four columns: SelectedApptDate, SelectedApptStartTime, SelectedApptEndTime, SelectedWeddingPlanner. You have to specify the other three columns as well in the SELECT statement.
