How to display MySQL data using tkinter in Python?

I am new to tkinter and trying to make an invoice application using this library. The app will read an Excel file using the Browse button and then save the Excel data into MySQL database which is working fine. However, when I press the Report button, it's not displaying the record on new window and getting halt all the time. Even a new window won't open, it should display the record on the current window. Here is my code:
# Import the required Libraries
from tkinter import *
from tkinter import ttk, filedialog
from tkinter.filedialog import askopenfilename
import mysql.connector
import xlrd
import tkinter as tk
from tkinter import filedialog
def browse_button():
# Allow user to select a directory and store it in global var
# called folder_path
global folder_path
filename = filedialog.askopenfilename()
folder_path.set(filename)
print(filename)
def show_new_window():
print("Show new window called")
# Create the new window
new_window = tk.Toplevel(app)
new_window.title("Report")
# Create a label in the new window
label = tk.Label(new_window, text="Delivery Report")
label.pack()
# Connect to the database
conn = mysql.connector.connect(user='root',
password='',
host='localhost',
database='magnetico')
mycursor = conn.cursor()
mycursor.execute("SELECT id_user, Vendor, KM FROM perorder")
# Get the results
result = mycursor.fetchall()
# Close the cursor and connection
mycursor.close()
conn.close()
# Create a button for each row in the result
for row in result:
button = tk.Button(new_window, text=str(row))
button.pack()
# Set the geometry of tkinter frame
app = tk.Tk()
app.geometry("900x800")
folder_path = tk.StringVar()
# Add a heading
heading = tk.Label(app, text="Click the Button to browse the Files", font=("Helvetica", 16))
heading.grid(row=0, column=1, columnspan=2)
lbl1 = tk.Label(app, textvariable=folder_path)
lbl1.grid(row=1, column=1, padx=10, pady=10, sticky=tk.NSEW)
# Center the button
button2 = tk.Button(app, text="Browse", command=browse_button)
button2.grid(row=1, column=2, padx=10, pady=10, sticky=tk.NSEW)
button = tk.Button(app, text="Report", command=show_new_window)
button.grid(row=2, column=2, padx=10, pady=10, sticky=tk.NSEW)
# Set the row and column weights
app.columnconfigure(1, weight=1)
app.columnconfigure(2, weight=1)
app.rowconfigure(1, weight=1)
app.mainloop()
# Connect to the database
conn = mysql.connector.connect(user='root',
password='',
host='localhost',
database='magnetico')
# Open the workbook
book = xlrd.open_workbook("mpo1.xls")
# Get the sheet you want
sheet = book.sheet_by_name("Order Details")
# Iterate through the rows of the sheet
for row_idx in range(sheet.nrows):
# Get the values in the row
row = sheet.row_values(row_idx)
# Insert the row into the database
cursor = conn.cursor()
cursor.execute("INSERT INTO perorder (mp_task_nr, batch_id, dropoff_sequence, id_user_payout_type, task_status, city, fleet, id_user, Name, Vendor, order_date, UID, KM, total_amount, Remarks) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s )", row)
conn.commit()

Python Tkinter text entry box to insert data to SQL Server

I have created a small python tkinter program designed to have a user write data into text entry boxes in the app then insert this data into a MS SQL server database. When clicking the insert button I am getting the following error message, stopping the app from insert the code into SQL.
cursor.execute("INSERT INTO TEST_DISA_MAIN_TABLE VALUES (:DENSITY_VALUE, :DATE, :TIME, :CHART_VALUE)",
pyodbc.ProgrammingError: ('The SQL contains 0 parameter markers, but 1 parameters were supplied', 'HY000')*
This is my code for the python insert function:
def insertvalue():
# Create a database or connect to one
conn = pyodbc.connect('Driver={SQL Server};'
'Server=MON-SQL-02;'
'Database=ENVIRONMENTAL;'
'Trusted_Connection=yes;')
# Create cursor
cursor = conn.cursor()
# Insert into table
cursor.execute("INSERT INTO TEST_DISA_MAIN_TABLE VALUES (:DENSITY_VALUE, :DATE, :TIME, :CHART_VALUE)",
{
'DENSITY_VALUE': DENSITY_VALUE.get(),
'DATE': DATE.get(),
'TIME': TIME.get(),
'CHART_VALUE': CHART_VALUE.get(),
})

I used this format to insert data into a sqlite3 db, but the same format is not working when inserting into a SQL Server database. I have tested the connection to the SQL server and can display values in the app so that part works correctly.

sqlite3.ProgrammingError: You did not supply a value for binding 1.

Hi #LoudEye and welcome to Stack Overflow! Try using ? instead of : like this:
c.execute("UPDATE mud SET mud_type=?,mud_weight = ?, mud_viscosity=?, mud_pit_number = ? WHERE...",(mud_type_editor.get(), mud_weight_editor.get(),mud_viscosity_editor.get(),mud_pit_number_editor.get()))
Note: You should also use WHERE also with question mark like I've used with SET

How to give Sqlite3 table name from a variable in Python

I'm in a dilemma as to how to give my table name depending on my Combobox selections. I am using PyQt5. I tried it this way but got not the thing right.
b = self.combo.currentText()
sql = '''CREATE TABLE IF NOT EXISTS d (id int, grade text)''')
This creates a database with b as the name instead of the choice from the combobox.

You have to bind the event based on combobox selection using application_cb.bind("<>", createTable) where you have to pass function name
application_label = Label(cbFrameRow1Col2, text='Application', bg='gray46', fg='white', font=("calibri", 10))
application_label.grid(row=0, column=0, sticky='w', padx=10, pady=5)
application_cb = ttk.Combobox(cbFrameRow1Col2, values=application_list, width=15)
application_cb.grid(row=0, column=1, sticky='w', padx=10, pady=5)
application_cb.bind("<<ComboboxSelected>>", createdb)
And now you have to call create table function when this event is triggered
def createTable(event):
tablename = application_cb.get()
conn = sqlite3.connect('temp.db')
cur = conn.cursor()
cur.execute("CREATE TABLE IF NOT EXISTS %s (id INTEGER PRIMARY KEY, Name TEXT)" % (tablename))
conn.commit()
conn.close()

How to display entry widget content in Treeview

Am trying to display content entered into entry widget in treeview after saving it in sqlite3 db.The content saved into db but doesn't display the id,Fist name and Surname contents in the treeview.
Your suggestion are welcome to achieve this.
from tkinter import ttk
import tkinter as tk
import sqlite3
def connect():
conn = sqlite3.connect("TRIAL.db")
cur = conn.cursor()
cur.execute("CREATE TABLE IF NOT EXISTS profile(id INTEGER PRIMARY KEY,
First TEXT, Surname TEXT)")
conn.commit()
conn.close()
def Insert():
conn = sqlite3.connect("TRIAL.db")
cur = conn.cursor()
fr=cur.execute("INSERT INTO profile (First, Surname) VALUES(?, ?)",
(first_text.get(), surname_text.get()))
conn.commit()
for items in fr:
tree.insert('', tk.END, values=items)
conn.close()
connect() # this to create the db
root = tk.Tk()
root.geometry("400x400")
tree= ttk.Treeview(root, column=("column", "colunn1"))
tree.heading("#0", text="NUMBER")
tree.heading("#1", text="FIRST NAME")
tree.heading("#2", text="SURNAME")
tree.pack()
first_text = tk.StringVar()
e1 = tk.Entry(root, textvariable=first_text)
e1.pack()
surname_text = tk.StringVar()
e2 = tk.Entry(root, textvariable=surname_text)
e2.pack()
b1 = tk.Button(text="add data", command=Insert)
b1.pack(side=tk.BOTTOM)
root.mainloop()

The problem in your code is that for items in fr does not work. Python sees fr as an empty iterable (put a print statement in the for loop and you will see that it is never executed). So, to insert the data in the treeview, you can get it directly from the entries and retrieve the db id with cur.lastrowid (I have found this solution in the answer to the question How to retrieve inserted id after inserting row in SQLite using Python?):
from tkinter import ttk
import tkinter as tk
import sqlite3
def connect():
conn = sqlite3.connect("TRIAL.db")
cur = conn.cursor()
cur.execute("CREATE TABLE IF NOT EXISTS profile(id INTEGER PRIMARY KEY, First TEXT, Surname TEXT)")
conn.commit()
conn.close()
def Insert():
conn = sqlite3.connect("TRIAL.db")
cur = conn.cursor()
data = (first_text.get(), surname_text.get())
# insert data in db
cur.execute("INSERT INTO profile (First, Surname) VALUES(?, ?)", data)
conn.commit()
# insert data in treeview
tree.insert('', tk.END, text=str(cur.lastrowid), values=data)
conn.close()
connect() # this to create the db
root = tk.Tk()
root.geometry("400x400")
tree= ttk.Treeview(root, column=("column", "colunn1"))
tree.heading("#0", text="NUMBER")
tree.heading("#1", text="FIRST NAME")
tree.heading("#2", text="SURNAME")
tree.pack()
first_text = tk.StringVar()
e1 = tk.Entry(root, textvariable=first_text)
e1.pack()
surname_text = tk.StringVar()
e2 = tk.Entry(root, textvariable=surname_text)
e2.pack()
b1 = tk.Button(text="add data", command=Insert)
b1.pack(side=tk.BOTTOM)
root.mainloop()
EDIT: If you use the columns '#1', '#2', '#3' to avoid using the special
column '#0', then you need to change a bit Insert: you need to pass the row id in values instead of text.
from tkinter import ttk
import tkinter as tk
import sqlite3
def connect():
conn = sqlite3.connect("TRIAL.db")
cur = conn.cursor()
cur.execute("CREATE TABLE IF NOT EXISTS profile(id INTEGER PRIMARY KEY, First TEXT, Surname TEXT)")
conn.commit()
conn.close()
def Insert():
conn = sqlite3.connect("TRIAL.db")
cur = conn.cursor()
data = (first_text.get(), surname_text.get())
# insert data in db
cur.execute("INSERT INTO profile (First, Surname) VALUES(?, ?)", data)
conn.commit()
# insert data in treeview
tree.insert('', tk.END, values=(str(cur.lastrowid),) + data)
conn.close()
connect() # this to create the db
root = tk.Tk()
root.geometry("400x400")
tree = ttk.Treeview(root, column=("column1", "column2", "column3"), show='headings')

tree.heading("#3", text="SURNAME")
tree.pack()
first_text = tk.StringVar()
e1 = tk.Entry(root, textvariable=first_text)
e1.pack()
surname_text = tk.StringVar()
e2 = tk.Entry(root, textvariable=surname_text)
e2.pack()
b1 = tk.Button(text="add data", command=Insert)
b1.pack(side=tk.BOTTOM)
