python如何实时查询oracle
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()
C:\Python27\python.exe C:/Users/tlcb/PycharmProjects/untitled/a6.py

print time.ctime()

# cursor = conn.cursor()
# xsql="select * from tlcb_mon_device a where a.ipaddr='10.3.244.1'"
