Python实现读取SQLServer数据并插入到MongoDB数据库的方法示例

yipeiwu_com6年前Python基础

本文实例讲述了Python实现读取SQLServer数据并插入到MongoDB数据库的方法。分享给大家供大家参考，具体如下：

db = client[db_name]
'''连接SqlServer数据库'''
connStr = 'DRIVER={SQL Server Native Client 11.0};SERVER=DESKTOP-44P34L6;DATABASE=Softput;UID=sa;PWD=sa'
conn = pyodbc.connect(connStr)
cursor = conn.cursor()
