mysql插入csv文件在python中不起作用

Question

I have tried many times and searched all over the internet and this is still not working for me. I am trying to read from a csv file and insert data into a database with python. This is my code, and I don't understand why it's not working

import mysql.connector
import csv
import pandas as pd

with open(r'files\files1.csv') as csv_file:
    csvfile = csv.reader(csv_file, delimiter=';')
    allvalues=[]
    for row in csvfile:
        value = (row[0],row[1],row[2])
        allvalues.append(value)

print(allvalues)

db = mysql.connector.connect(
    host = 'ip',
    user = 'user',
    passwd = 'pass',
    database = 'db',
    auth_plugin='mysql_native_password'
)

cursor = db.cursor()

query = "INSERT INTO table1 (col1, col2, col3) VALUES (%s , %s , %s)"

cursor.execute(query, allvalues)

db.commit()

this gives the following error:

   result = self._cmysql.convert_to_mysql(*params)
_mysql_connector.MySQLInterfaceError: Python type tuple cannot be converted

I also want to mentions that I have tried many other things to insert into the table not only the method above, and everytime I get a different error.

Can someone please tell me how do I do it? I would really appreciate it

Thank you very much

Answer 1

use cursor.executemany(query, allvalues)

If you have multiple elements which are saved in a list or tuple then use,

cursor.executemany(query, list) or cursor.executemany(query, tuple)

Or you can use for loop

for value in allvalues:
    cursor.execute(query, value)
