本文實(shí)例講述了python使用 cx_Oracle 模塊進(jìn)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_Oraclefrom pprint import pprintimport csvimport timeimport reimport binasciiprint 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 rexcept Exception,e: print e print type(e) print str(e).decode('UTF-8').encode('GBK') print time.ctime()
