具体如下:
# !/usr/bin/env python # -*- coding: utf-8 -*- import cx_Oracle from pprint import pprint import csv import time import re import binascii print time.ctime() try: conn = cx_Oracle.connect('tlcbuser/tlcbuser@10.5.100.232/tlyy') # cursor = conn.cursor() # xsql="select * from tlcb_mon_device a where a.ipaddr='10.3.244.1'" # r = cursor.execute(xsql) # print r except Exception,e: print e print type(e) print str(e).decode('UTF-8').encode('GBK') print time.ctime()
C:\Python27\python.exe C:/Users/tlcb/PycharmProjects/untitled/a6.py
