Question

我正在尝试插入下表

  | id | Dairy_free | Gluten_free | Vegetarian | Vegan|  ketagonic|
  +----+------------+-------------+------------+------+-----------+

来自python字典的行，其值无序（有些缺失）。
例如，字典中的元素之一可以是：

"Vegetarian": true, 
"Vegan": true, 
"ketagonic": false,
"recipe_id": 776990

因此，通过迭代字典，我创建了一个键值字符串元组以插入到特定的列中，例如mysql doc中的示例：

ALLERGIES_INSERT_SQL = ("INSERT INTO allergies (%s) VALUES (%s)")

for allergies_dict in allergies_list:
    keys_as_string = ", ".join(list(allergies_dict.keys()))
    values = list(allergies_dict.values())
    values_as_strings = ", ".join([str(val) for val in values])

    #now keys are in the form of 'Dairy_free, Gluten_free, Vegetarian, Vegan, recipe_id, ketagonic'
    #and the values in the form of 'False, True, True, False, 521693, False'

    cursor.execute(ALLERGIES_INSERT_SQL, (keys_as_string, values_as_strings))

但是我收到语法错误消息

ProgrammingError(1064, "1064 (42000): 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 '?) VALUES (?)' at line 1", '42000')

MySQL游标使用列子集插入语法错误
