Question

i am working in winforms with C#. heres my code

query = "SELECT max(Appointment_Time) FROM Appointments WHERE (Appointment_Status = 'D')";
dset = db.GetRecords(query,"Appointments");
ctime_Label.Text = dset.Tables["Appointments"].Rows[0]["Appointment_Time"].ToString();

db.GETRecords is a function of the class that provides me sql-services, simply returns me a dataset. i keep getting the error “the column ‘Appointment_Time’ doesnot belong to the table Appointments” which is stupid cuz

• when i am inserting the values its
  working fine.
• when i am NOT using
  max(Appointment_Time) function it is
  working fine

wha is the problem here.. i think there is something to do with the max() function. Any suggestion or alternative for this

Answer 1

Run the query in SQL Server and see what you get.

Now try:

 SELECT max(Appointment_Time) as A_Time FROM Appointments WHERE (Appointment_Status = 'D')";

and then

 ctime_Label.Text = dset.Tables["Appointments"].Rows[0]["A_Time"].ToString();
