This is my code:

import mysql.connector 
mydb = mysql.connector.connect(host='localhost', 
                        database='glabo', 
                        user='root', 
                        password='.........') 
mycursor = mydb.cursor()
mycursor.execute("INSERT INTO orders (o_userid, o_labo, o_jour, o_heure) SELECT users.user_id, labos.l_id, jours.j_id, heures.h_id FROM users, labos, jours, heures WHERE users.user_name = 'Kbayad' AND labos.l_nom = 'LABO 1' AND jours.j_jour = 'Mardi' AND heures.h_heure = '10-12';")

After running this python code, I don’t get any error but nothing changes in the database
