Cut out the database query code into a new file and focus on that. The error is very clear. Your table does not have a column named "use_medication". You need to find out why you think it does. Once you get the database all cleared up you can move the correct code back into your GUI.

I suggest a similar approach for the GUI. Work on a small section and get that to work with the database, then add features.

At a glance there are some problems, like this:

        cmbNameTablets = StringVar()
        Ref = StringVar()
        Dose = StringVar()
        NumberTables = StringVar()
        AppointmentDate = StringVar()
        IssuedDate = StringVar()
        HowtoUseMedication = StringVar()  # Added HowtoUseMedication variable
        PatientID = StringVar()
        PatientNHSNo = StringVar()
        PatientName = StringVar()
        DateOfBirth = StringVar()
        PatientAddress = StringVar()
        Prescription = StringVar()
        DoctorName = StringVar()

All these variables disappear as soon as the Hospital.__init__() method completes. If Hospital needs these variables, they should be instance variables (self.doctor_name = StringVar()).

I know you know about instance variables because you use them elsewhere in your code, like here:

        self.lblLabel = Label(FrameDetail, font=('arial', 10, 'bold'), pady=8,
                    text="Type of medical condition/Does the patient use medications?")
        self.lblLabel.grid(row=0, column=0)

But I have to wonder why you keep self.lblLabel in an instance variable. These two lines are the only place it is used. It is never referenced again. Create instance variables for things you need to reference later. Use local variables for things you only refer in the init. Or use no variable at all. Why not do this:

tk.Label(
    FrameDetail, font=('arial', 10, 'bold'), pady=8, text="Type of medical condition/Does the patient use medications?"
).grid(row=0, column=0)

Your GUI should have maybe 3 fonts max. I prefer one. Your code makes 38 fonts. Most of these fonts are the same, but it is very easy to make a typo when you repeat something 38 times. Instead of defining the same font over an over, make an object that you can use over and over.

small_font = ('arial', 10, 'bold')  # define once
 self.lblLabel =tk.Label(

This drives me nuts. I see it all the time and it makes no sense.

class Hospital:
    def __init__(self, root):
        self.root = root
        self.root.title("Hospital Management System")

if __name__ == '__main__':
    root = Tk()
    application = Hospital(root)
    root.mainloop()

Why is Hospital passed a root? Shouldn't Hospital be a root?

class Hospital(tk.Tk):
    """The main window for my hospital management system."""
    def __init__(self):
        super().__init__()
        self.title("Hospital Management System")

if __name__ == '__main__':
     Hospital().mainloop()

Hope you don't mind but, I spruced up your app a little.
I didn't do any of the database functions as I don't really know what you are wanting them to do.
On a side note you have a delete and reset button. If you delete a record from the database, it can't be reset.

Here is the code

import tkinter as tk
import tkcalendar

    def __init__(self):
        pass

        self.parent.title('Hospital Management System Version 0.01')

Maybe the CREATE command has a problem?

Instead of AUTOINCREMENT try AUTO_INCREMENT? Otherwise AUTOINCREMENT may be interpreted as a column name.

Quote:CREATE TABLE IF NOT EXISTS patients (
id INTEGER PRIMARY KEY AUTO_INCREMENT,
reference_no TEXT,
issued_date TEXT,
appointment_date TEXT,
patient_id TEXT,
patient_name TEXT,
date_of_birth TEXT,
patient_address TEXT,
nhs_number TEXT,
name_of_tablets TEXT,
no_of_tablets TEXT,
dose TEXT,
use_medication TEXT,
doctor_name TEXT
)

This works in my MySQL database:

Quote:INSERT INTO patients (
reference_no, issued_date, appointment_date, patient_id, patient_name, date_of_birth,
patient_address, nhs_number, name_of_tablets, no_of_tablets, dose, use_medication, doctor_name
) VALUES ('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M')

SELECT id, use_medication, doctor_name FROM patients WHERE 1
