使用python将csv数据导入mysql数据库

pip install pandas mysql-connector-python

import mysql.connector

# 连接到 MySQL 数据库
mydb = mysql.connector.connect(
    host="localhost",
    user="yourusername",
    password="yourpassword",
    database="yourdatabase"
)

​​​​​​​# 创建游标对象
cursor = mydb.cursor()

import pandas as pd
​​​​​​​# 读取 CSV 文件
df = pd.read_csv("data.csv")

# 遍历 DataFrame 中的每一行，并将数据插入到 MySQL 数据库中
for index, row in df.iterrows():
    sql = "INSERT INTO your_table_name (column1, column2, column3, ...) VALUES (%s, %s, %s, ...)"
    values = (row['column1'], row['column2'], row['column3'], ...)
    cursor.execute(sql, values)
​​​​​​​# 提交更改
mydb.commit()

# 关闭游标和数据库连接
cursor.close()
mydb.close()
