    栏目:Linux/apache问题 时间:2019-12-07 16:45

    本文实例讲述了python使用 cx_Oracle 模块进行查询操作。分享给大家供大家参考,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()

    # cursor = conn.cursor()
