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

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

'''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()
