本文介绍了一个Python脚本，该脚本利用xlrd、xlwt和pymssql库实现从SQL Server数据库中读取数据并批量写入到Excel文件中，同时支持从Excel读取数据追加到同一工作簿。脚本展示了如何使用正则表达式处理HTTP请求返回的数据，以及如何通过SQL查询获取商品信息。

                           database='xxxxxxxxxxx',
                           charset='utf8')

    #查看连接是否成功
    cursor = conn.cursor()
    sql = ssql
    cursor.execute(sql)
    #用一个rs变量获取数据
    rs = cursor.fetchall()
