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：

# -*- coding: utf-8 -*-

import pyodbc

import os

import csv

import pymongo

from pymongo import ASCENDING,DESCENDING

from pymongo import MongoClient

import binascii

'''连接mongoDB数据库'''

client = MongoClient('10.20.4.79',27017)

#client = MongoClient('10.20.66.106',27017)

db_name = 'SoftADoutput'

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()
