Why is the database not populated?

Question

Python

There is this code:

import sqlite3 as sq

conn = sq.connect("main.db", check_same_thread=False) 
cur = conn.cursor()
cur.execute("""CREATE TABLE IF NOT EXISTS users( 
    username TEXT, 
    id_tele TEXT,
    user_id INTEGER PRIMARY KEY
)""")

@bot.message_handler(commands=['start'])
def welc(message):
    idUser = message.from_user.id
    userName = message.from_user.first_name
    bot.send_message(message.chat.id, "Что хотите узнать?")
    cur.execute("INSERT INTO users(username, id_tele) VALUES(:name, :id)", {'name': userName, 'id': idUser})
    cur.close()

cur.close() was added, because there were errors, but not with it.
For some reason, the database is not filled

Answer 1

After cur.execute... you need to add conn.commit()
