您能帮我解决带变量的Python Sqlite3问题吗？

Question

[我正在创建电报机器人，在其中获取电报ID并将其放置在变量中。当我在数据库中对查询使用变量时，出现“ TypeError：函数最多接受2个参数（给定3个）”。

没有查询，变量工作正常。这是一些代码：

import db
from aiogram import types
import expenses
from typing import List, NamedTuple, Optional

class Expense(NamedTuple):
id: Optional[int]
amount: int
category_name: str

def test_last():
    cursor = db.get_cursor()
    asd = types.User.get_current().id #user id 
    cursor.execute("select id, amount, name "
        "from expense,category where codename=category_codename and user_id= ?" ,asd,
        "order by created desc limit 10")
    rows = cursor.fetchall()
    last_expenses = [Expense(id=row[0], amount=row[1], category_name=row[2]) for row in rows]
    return(last_expenses)

Answer 1

cursor.execute的语法是

1. 查询字符串
2. 元组/参数迭代

so

cmd = ("select id, amount, name from expense,category where " +
       "codename=category_codename and user_id= ? " +
       "order by created desc limit 10")

cursor.execute(cmd, (asd,) )

应该工作。
