Flask-Mysql Python 将 table 更新为 Mysql 时出现 1064 错误

Question

在使用 Flask python.

构建 Web 应用程序时，由于此更新 mysql table 错误而被困了一整天

(1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE 'user_id'='28'' at line 1")

根据 Whosebug 中类似问题的解决方案，尝试删除逗号并添加 ``，但它不起作用。

@app.route('/update')
def update():
    try:
        conn = mysql.connect()
        update = conn.cursor(pymysql.cursors.DictCursor)
        sql = "UPDATE user SET user_photo=%s, WHERE user_id=%s"
        _path="User.30.1.jpg"
        _id="28"
        data = (_path,_id)
        update.execute(sql,data)
        conn.commit()
        return render_template('training.html')
    except Exception as e:
        print(e)

从 sql 变量中删除逗号：

sql = "UPDATE user SET user_photo=%s WHERE user_id=%s"
