csv怎么导入mysql数据库-乐工具技术知识

要将CSV文件导入MySQL数据库，您可以按照以下步骤操作：

确保您已经安装了MySQL数据库和Python环境。
打开命令行或终端，输入以下命令以安装mysql-connector-python库（如果尚未安装）：

pip install mysql-connector-python

创建一个CSV文件，例如data.csv，并确保其内容格式正确。例如：

id,name,age
1,Alice,30
2,Bob,25
3,Charlie,22

编写Python脚本以将CSV数据导入MySQL数据库。以下是一个示例脚本：

import csv
import mysql.connector
from mysql.connector import Error

# 连接到MySQL数据库
try:
    connection = mysql.connector.connect(
        host='localhost',
        user='your_username',
        password='your_password',
        database='your_database'
    )

    if connection.is_connected():
        cursor = connection.cursor()

        # 删除表（如果存在）
        cursor.execute("DROP TABLE IF EXISTS your_table")

        # 创建新表
        create_table_query = """CREATE TABLE your_table (
                                    id INT PRIMARY KEY,
                                    name VARCHAR(255),
                                    age INT
                                );"""
        cursor.execute(create_table_query)

        # 读取CSV文件并插入数据
        with open('data.csv', mode='r') as csvfile:
            csv_reader = csv.DictReader(csvfile)
            insert_query = "INSERT INTO your_table (id, name, age) VALUES (%s, %s, %s)"
            cursor.executemany(insert_query, csv_reader)

        # 提交更改并关闭连接
        connection.commit()
        print("CSV data has been successfully imported to MySQL database.")

except Error as e:
    print(f"Error while connecting to MySQL: {e}")

finally:
    if connection.is_connected():
        cursor.close()
        connection.close()
        print("MySQL connection is closed")
