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(),
})
# Commit changes
conn.commit()
#Close Connection
conn.close()
# Clear the text boxes
DENSITY_VALUE.delete(0, END)
DATE.delete(0, END)
TIME.delete(0, END)
CHART_VALUE.delete(0, END)
#Create text boxes
DENSITY_VALUE = Entry(root, width=30)
DENSITY_VALUE.grid(row=2, column=1)
DATE = Entry(root, width=30)
DATE.grid(row=3, column=1)
TIME = Entry(root, width=30)
TIME.grid(row=4, column=1)
CHART_VALUE = Entry(root, width=30)
CHART_VALUE.grid(row=5, column=1)
#Create Text box labels
DENSITY_VALUE_Label = Label(root, text="Density Value")
DENSITY_VALUE_Label.grid(row=2, column=0)
DATE_Label = Label(root, text="Date")
DATE_Label.grid(row=3, column=0)
TIME_Label = Label(root, text="Time")
TIME_Label.grid(row=4, column=0)
CHART_VALUE_Label = Label(root, text="Chart Value")
CHART_VALUE_Label.grid(row=5, column=0)
button = Button(root, text = "Show All Values", command = showvalues)
button.grid(row=0, column=0)
button = Button(root, text = "Insert Values", command = insertvalue)
button.grid(row=1, column=0)
#Commit changes
conn.commit()
# Close connection
conn.close()
root.mainloop()
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.

How to create a search bar for a table from DB Browser

I'm trying to find a way to create a search bar for a table connected to a DB Browser database. The search bar I'm looking for is the one where you type in the bar, and the program will "hide" any data that does not follow the "requirements" while leaving the ones that do visible. The following code shows what I've tried so far. Hopefully, I made myself clear, and thank you for your help. I don't know how to attach the database so sorry for the inconvenience.
If you remove the code between the '''Triple Apostrophes,''' you should see a table with a button that says SELECT which reveals the data. The Table shown is where I would like the Search bar to control.
Thank you for your help once again.

How to delete a specific occurrence with a delete button?

I have an iteration in my code which show for each line : ID / Name / Button Delete. You can see the image below. I would like when i click on one of the delete button that the data on the same line be deleted.
I try my best, you can see my code. How i can do it ?
Thank you a lot.
from tkinter import *
import mysql.connector
def main():
root = Tk()
conn = mysql.connector.connect(user='root', password='', host='localhost',
database='showmanager')
my_cursor = conn.cursor()
var_i = 3
def del_customer():
my_cursor.execute("DELETE FROM `spectator` "
"WHERE `spectator`.`id_customer` = "+user[0]+"")
my_cursor.execute("SELECT * FROM spectator")
users = my_cursor.fetchall()
for user in users:
label = Label(root, text=user, font=9)
label.grid(row=int(var_i), column=1)
Button(root, text="Delete spectator", font=9, height=1,
command=del_customer).grid(row=int(var_i), column=4)
var_i = var_i + 1
root.mainloop()
if __name__ == '__main__':
main()

You can pass the customer ID and corresponding widgets (label and button) to del_customer() so that you can remove the record in the database based on the customer ID and the corresponding label and button inside the function:
def del_customer(cust_id, widgets):
my_cursor.execute("DELETE FROM spectator WHERE id_customer = %s", [cust_id])
conn.commit() # make the change effective
# remove the corresponding label and button
for w in widgets:
w.destroy()
...
for user in users:
label = Label(root, text=user)
label.grid(row=var_i, column=1)
btn = Button(root, text="Delete spectator")
btn.grid(row=var_i, column=4)
var_i += 1
# pass the customer ID, label and button to del_customer()
btn['command'] = lambda cust_id=user[0], widgets=(label, btn): del_customer(cust_id, widgets)

How to trigger a run button based on all the values in a list?

I have a Tkinter app and inside that app I have an OptionMenu which is giving me all the id's that are located in the list vehicleid. Please note that this list can become bigger or smaller.
Now I want my button to send the data of owner and vehicleid to a database based on what the user selects. So if I have for example 2 vehicleid's, I first need to select a specific vehicleid and for every vehicleid I need to select a specific owner.
So in case of 2 vehicleid my database should look like this:
vehicleid owner
C161 --- Spain
C162 --- United Kingdom
App looks like this:
This is my code:
owner = ['Spain', 'United Kingdom', 'Malaysia']
vehicleid = ['C161', 'C162']
window = Tk()
window.title("Running Python Script") # Create window
window.geometry('550x300') # Geo of the window
##These are the option menus
dd_owner = StringVar(window)
dd_owner.set(owner[0]) # the first value
w = OptionMenu(window, dd_owner, *owner)
w.grid(row=1, column=1)
dd_id = StringVar(window)
dd_id.set(vehicleid[0])
w0 = OptionMenu(window, dd_id, *vehicleid)
w0.grid(row=0, column=1)
##The run button
run_list_button =Button(window, text="Send data of ID's to database!")
run_list_button.grid(column=0, row=3)
##These are the titles
l1 = Label(window, text='Select Owner', width=15)
l1.grid(row=1, column=0)
l0 = Label(window, text='Select vehicle id:', width = 30)
l0.grid(row=0, column=0)
mainloop()

To begin with, you should store the data somewhere(a dictionary or a file..) and then read the data when the user presses the button.
import mysql.connector as mysql
....
mydb = mysql.connect(host = 'localhost',user = 'root',passwd = '****.',database = 'table_data')
data = {}
def store():
if dd_id.get() not in data:
data[dd_id.get()] = dd_owner.get()
print(data)
def upload():
cur = mydb.cursor()
for item in data.items():
sql = 'INSERT INTO table_data VALUES (%s,%s)'
params = (item[0],item[1])
cur.execute(sql,params)
mydb.commit()
print('Done')
....
# The store button
Button(window, text="Store data!",command=store).grid(column=0, row=3)
# The database button
Button(window, text="Send to database",command=upload).grid(column=0, row=4)
This will store the data in the database when the respective buttons are clicked, also duplicate entries or updatiion of entries will not be allowed.

Though your question is confusing. After looking at your discussion I understand that you want to send all data to the database only after the users have confirmed their choice.
In that case, you probably need a dictionary where you store both vehicle_id and owner {"vehicle_id": [], "owner": []} until the user clicks on the update database button. Once you have updated the database make sure to empty the dictionary so the previously selected items are not inserted into the database again.
Note: you would still need another button to be pressed several times to insert data into the dictionary. You can choose not to have the button by using the trace method of the control variable
Here is an example
from tkinter import *
import sqlite3
CREATE_QUERY = "CREATE TABLE IF NOT EXISTS vehicle(vehicle_id VARCHAR(5), owner VARCHAR(100));"
INSERT_QUERY = "INSERT INTO vehicle(vehicle_id, owner) VALUES(?, ?);"
SELECT_QUERY = "SELECT * FROM vehicle;"
sql_file = "sample.db"
id_dict = {"vehicle_id": [], "owner": []}
def create_data_base():
with sqlite3.connect(sql_file) as conn:
conn.execute(CREATE_QUERY)
conn.commit()
def insert_to_db():
global id_dict
with sqlite3.connect(sql_file) as conn:
for value in zip(*id_dict.values()):
conn.execute(INSERT_QUERY, value)
conn.commit()
id_dict = {"vehicle_id": [], "owner": []} # empty the list once you insert the data
display_data()
def display_data():
with sqlite3.connect(sql_file) as conn:
curr = conn.cursor()
curr.execute(SELECT_QUERY)
items = curr.fetchall()
print(items)
def add():
id_dict["vehicle_id"].append(dd_id.get())
id_dict["owner"].append(dd_owner.get())
print(id_dict)
owner = ['Spain', 'United Kingdom', 'Malaysia']
vehicleid = ['C161', 'C162']
window = Tk()
window.title("Running Python Script") # Create window
window.geometry('550x300') # Geo of the window
create_data_base()
##These are the option menus
dd_owner = StringVar(window)
dd_owner.set(owner[0]) # the first value
w = OptionMenu(window, dd_owner, *owner)
w.grid(row=1, column=1)
dd_id = StringVar(window)
dd_id.set(vehicleid[0])
w0 = OptionMenu(window, dd_id, *vehicleid)
w0.grid(row=0, column=1)
Button(window, text='Add', command=add).grid(column=1, row=3)
##The run button
run_list_button =Button(window, text="Send data of ID's to database!", command=insert_to_db)
run_list_button.grid(column=0, row=3)
##These are the titles
l1 = Label(window, text='Select Owner', width=15)
l1.grid(row=1, column=0)
l0 = Label(window, text='Select vehicle id:', width = 30)
l0.grid(row=0, column=0)
window.mainloop()
The above code will insert all the data from the dictionary to the database.

Python / Tkinter - Error message when I try to save changes

I am building a database for tools and matrials list in Python using Tkinter for the GUI. I am running into issues when I try to edit data.

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
