尝试以二进制形式插入 uuid 数据 - 总是出现语法错误

Question

我正在尝试通过 python 在 MySql DB 中插入一个 uuid 数据作为 binary(16)。我正在按照 python 教程进行操作，仅针对插入语法，并且总是得到一个 syntax error 并且我不知道错误在哪里。

对于 uuid 部分，我在 SO 中看到了一些 post，我认为应该可行。

ps：我是新手。

我有一个单独的 class 作为连接句柄。

代码：

import uuid
import json
from db_connection import Connection

f = open('logs.txt', "r")

lines = f.readline()

json_line = json.loads(lines)

print(json_line)

add_consumer = ("INSERT INTO consumer "
               "(id) "
                "VALUES (%s)")

#consultation purpose - from:https://dev.mysql.com/doc/connector-python/en/connector-python-#example-cursor-transaction.html
#
# add_employee = ("INSERT INTO employees "
#                "(first_name, last_name, hire_date, gender, birth_date) "
#                "VALUES (%s, %s, %s, %s, %s)")
# add_salary = ("INSERT INTO salaries "
#               "(emp_no, salary, from_date, to_date) "
#               "VALUES (%(emp_no)s, %(salary)s, %(from_date)s, %(to_date)s)")

connection = Connection()
connection.open_connection()
cursor = connection.get_cursor()

consumer = json_line['authenticated_entity']['consumer_id']['uuid']
consumer_uuid = uuid.UUID(consumer)

print("\n", consumer, "\n", consumer_uuid)
#prints
#72b34d31-4c14-3bae-9cc6-516a0939c9d6 
#72b34d31-4c14-3bae-9cc6-516a0939c9d6

cursor.execute(add_consumer, consumer_uuid.bytes)
connection.commit_data()

cursor.close()
connection.close_connection()

错误：

Answer 1

cursor.execute() 的参数参数必须是元组或字典。

示例：

cursor.execute(add_consumer, (consumer_uuid.bytes,) )
