Как реализовать базу данных в Tkinter, переключающуюся между фреймами?

Я работаю на основе Переключение между двумя кадрами в tkinter, и это все еще проект, но у меня периодически возникают проблемы с использованием баз данных.

Вот мой код:

import tkinter as tk

import sqlite3

import threading

class SampleApp(tk.Tk):

    def __init__(self, *args, **kwargs):

        tk.Tk.__init__(self, *args, **kwargs)

        self.resizable(0,0)

        self.title("Findex")

        w, h = self.winfo_screenwidth(), self.winfo_screenheight()

        self.overrideredirect(1)

        self.geometry("%dx%d+0+0" % (w, h))

        container = tk.Frame(self)

        container.pack(side = "top", fill = "both", expand = True)

        container.grid_rowconfigure(0, weight = 1)

        container.grid_columnconfigure(0, weight = 1)

        self.frames = {}

        for F in (Inicio, Registro, RegistroError, Consulta):

            page_name = F.__name__

            frame=F(parent = container, controller = self)

            self.frames[page_name] = frame

            frame.grid(row = 0, column = 0, sticky = "nsew")

        self.show_frame("Inicio")

    def show_frame(self, page_name):

        frame = self.frames[page_name]

        frame.tkraise()

    def get_page(self, page_class):

        return self.frames[page_class]

class Inicio(tk.Frame):

    def __init__(self, parent, controller):

        tk.Frame.__init__(self, parent)

        self.controller = controller

        labelInicio = tk.Label(self, text = "Bienvendido a Findex")

        labelInicio.pack()

        botonIncio = tk.Button(self, text = "Comenzar", 
            command = lambda: controller.show_frame("Registro"))

        botonIncio.pack()

                  " ¿es correcto?")

                labelNombre.pack()

Я ожидаю написать название, марку или магазин продукта и вставить всю информацию о продуктах, которые соответствуют записи в текстовом поле, но это дает мне «OperationalError» или «sqlite3.ProgrammingError».
