python使用 cx_Oracle 模組進行查詢操作示例
本文例項講述了python使用 cx_Oracle 模組進行查詢操作。分享給大家供大家參考,具體如下:
# !/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/[email protected]/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

# !/usr/bin/env python # -*- coding: utf-8 -*- import cx_Oracle from pprint import pprint import csv import time import re import binascii import os os.environ['NLS_LANG'] = 'SIMPLIFIED CHINESE_CHINA.UTF8' print time.ctime() try: conn = cx_Oracle.connect('tlcbuser/[email protected]/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 time.ctime()
