Executemany 因“执行操作失败；无法处理参数”而失败答案

【问题标题】：Executemany is failing with "Failed executing the operation; Could not process parameters"Executemany 因“执行操作失败；无法处理参数”而失败

【问题描述】：

我正在尝试使用cursor.executemany() 调整我的python 代码的INSERT INTO 性能，但我收到了一些错误。
代码：

import mysql.connector

mydb = mysql.connector.connect(
    host="database1",
    user="username1",
    passwd="password1",
    database="dbname"
)

data = [
  'A',
  'B',
  'C',
]

mycursor = mydb.cursor()
query = "INSERT INTO table_name (name) VALUES (%s)"
mycursor.executemany(query, data)
mydb.commit()

根据the example，这应该可以，但是，我收到错误：

Traceback (most recent call last):
  File "/Users/filipniko/PycharmProjects/scrape/darwin-scrape/venv/lib/python3.7/site-packages/mysql/connector/cursor_cext.py", line 308, in _batch_insert
    prepared = self._cnx.prepare_for_mysql(params)
  File "/Users/filipniko/PycharmProjects/scrape/darwin-scrape/venv/lib/python3.7/site-packages/mysql/connector/connection_cext.py", line 632, in prepare_for_mysql
    raise ValueError("Could not process parameters")
ValueError: Could not process parameters

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "dbtest.py", line 18, in <module>
    mycursor.executemany(query, data)
  File "/Users/filipniko/PycharmProjects/scrape/darwin-scrape/venv/lib/python3.7/site-packages/mysql/connector/cursor_cext.py", line 350, in executemany
    stmt = self._batch_insert(operation, seq_params)
  File "/Users/filipniko/PycharmProjects/scrape/darwin-scrape/venv/lib/python3.7/site-packages/mysql/connector/cursor_cext.py", line 329, in _batch_insert
    "Failed executing the operation; %s" % err)

mysql.connector.errors.InterfaceError: Failed executing the operation; Could not process parameters

注意事项：

表为空
我可以使用 mycursor.execute 为列表中的每个项目添加行

表架构如下所示：

+-------+--------------+------+-----+---------+----------------+
| Field | Type         | Null | Key | Default | Extra          |
+-------+--------------+------+-----+---------+----------------+
| id    | int(11)      | NO   | PRI | NULL    | auto_increment |
| name  | varchar(100) | NO   | UNI | NULL    |                |
+-------+--------------+------+-----+---------+----------------+

我做错了什么？

【解决方案1】：

我发现我使用了错误的依赖项，我应该使用mySQLdb 而不是mysql.connector：

import MySQLdb as my

mydb = my.connect(
    host="database1",
    user="username1",
    passwd="password1",
    database="dbname"
)

data = [
  'A',
  'B',
  'C',
]

mycursor = mydb.cursor()
query = "INSERT INTO table_name (name) VALUES (%s)"
mycursor.executemany(query, data)
mydb.commit()
