Я хочу обновить несколько столбцов в моей таблице «Класс» в sqlite. Я не знаю, как это сделать, поэтому я подошел к тому же синтаксису, что и запрос INSERT, однако, похоже, у меня следующая синтаксическая ошибка: sqlite3.OperationalError: near "VALUES": syntax error
Строка, с которой сейчас возникают проблемы,
e_sql= "UPDATE Class SET (ClassType,Location,UserID,Staff,Time) VALUES (?,?,?,?,?)"
c.execute(e_sql,(classes,location,r,staff,time))
Мне просто интересно, как создать запрос для обновления нескольких столбцов в моей таблице «Класс». Вот мой текущий код:
#imports
from tkinter import *
from tkinter import messagebox as ms
from tkinter import ttk
import sqlite3
from PIL import Image,ImageTk
import datetime
global time
time = datetime.datetime.now()
with sqlite3.connect('Gym.db') as db:
c = db.cursor()
c.execute('CREATE TABLE IF NOT EXISTS Users (UserID INTEGER PRIMARY KEY,FirstName TEXT ,LastName TEXT ,Gender TEXT,Email TEXT NOT NULL,Phone TEXT NOT NULL,Username TEXT NOT NULL,Password TEXT NOT NULL);')
c.execute('CREATE TABLE IF NOT EXISTS Staff (StaffID INTEGER PRIMARY KEY, Role TEXT NOT NULL, Name TEXT);')
c.execute('CREATE TABLE IF NOT EXISTS Gym (GymID INTEGER PRIMARY KEY, Location TEXT);')
c.execute('CREATE TABLE IF NOT EXISTS Class (ClassID INTEGER PRIMARY KEY, ClassType TEXT, Location TEXT, UserID INTEGER, Staff TEXT, StaffID INTEGER, Time TEXT, FOREIGN KEY (UserID) REFERENCES Users(UserID), FOREIGN KEY (StaffID) REFERENCES Staff (StaffID));')
db.commit()
db.close()

with sqlite3.connect('Gym.db') as db:
c = db.cursor()
c.execute('SELECT UserID FROM Users WHERE Username = (?) AND Password =(?)', (str(username),str(password)))
result = c.fetchall()
for row in result:
