mssql 与mysql转换

import pyodbc
import mysql.connector
import csv

# 连接到MSSQL数据库
mssql_conn = pyodbc.connect('DRIVER={SQL Server};SERVER=your_server;DATABASE=your_db;UID=your_user;PWD=your_password')
mssql_cursor = mssql_conn.cursor()

# 连接到MySQL数据库
mysql_conn = mysql.connector.connect(host='your_mysql_host', database='your_mysql_db', user='your_mysql_user', password='your_mysql_password')
mysql_cursor = mysql_conn.cursor()

# 查询MSSQL数据库中的数据
mssql_cursor.execute("SELECT * FROM your_table")
rows = mssql_cursor.fetchall()

# 将数据写入CSV文件
with open('output.csv', 'w', newline='', encoding='utf-8') as csvfile:
    csv_writer = csv.writer(csvfile)
    csv_writer.writerow([i[0] for i in mssql_cursor.description])  # 写入列名
    csv_writer.writerows(rows)

# 读取CSV文件并插入到MySQL数据库中
with open('output.csv', 'r', encoding='utf-8') as csvfile:
    csv_reader = csv.reader(csvfile)
    next(csv_reader)  # 跳过列名
    for row in csv_reader:
        mysql_cursor.execute("INSERT INTO your_mysql_table VALUES (%s, %s, %s)", row)

# 提交事务并关闭连接
mysql_conn.commit()
mssql_conn.close()
mysql_conn.close()
