使用3个参数更新Python Sqlite

晚上好。我有一个相当基本的python应用程序，它将sqlite数据库加载到gui中，并提供用户crud功能

我的添加和删除功能工作正常，但我正在努力查询更新而没有问题

我需要用3个变量制作这个update语句 self.tempColumn：要更新的所需列的名称 cheese\u id：要更新的记录的id 值：用于更新字段的值

我已经打印出了所有3个值，它们返回了我所期望的结果，但是我无法在不崩溃的情况下运行更新查询

    def run_query(self, query, parameters=()):
    with sqlite3.connect(self.db_name) as conn:
        cursor = conn.cursor()
        result = cursor.execute(query, parameters)
        conn.commit()
        return result



    def delete_record(self, cheese_id):

    query = 'DELETE FROM ' + self.working_table + " where CheeseId=" + cheese_id
    self.run_query(query, )

    conn = sqlite3.connect('canadianCheeseDirectory')
    cursor = conn.cursor()
    cursor.execute("UPDATE cheeseData SET " + self.tempColumn + ' = ' + value + " WHERE CheeseId=" + cheese_id)

这不起作用：（

我尝试过很多形式，但都没有用，包括

self.run_query(
        """UPDATE cheeseData SET {}=? WHERE CheeseId = ?""".format(self.tempColumn),
        (value, cheese_id), )




self.run_query('UPDATE cheeseData set %s=%s WHERE CheeseId = $s'(self.tempColumn, value, cheese_id))
self.run_query('UPDATE cheeseData set %s=? WHERE CheeseId = ?VALUES(?,?)'.format(self.tempColumn)value, cheeseid)

我意识到为查询连接字符串是不好的做法，但这是本地sqlite db文件上的一个简单应用程序，我只是尝试提供一个gui crud

任何帮助都将不胜感激。

对于调试，请将

UPDATE

语句转换成一个字符串，并在控制台上打印出来，以查看它是否正常。同时尝试在SqlLite命令行中运行相同的命令，看看是否有错误。谢谢@anuragal，这是一个令人难以置信的建议。我成功地打印了该语句，直到它恢复正常似乎很合适，但不适用于

query=“”更新集合{}={}，其中CheeseId={}”“。格式（self.tempColumn，value，cheese_id）

好消息：-）
