windows下python连接oracle数据库

python连接oracle数据库的方法,具体如下

1.首先安装cx_Oracle包
2.解压instantclient-basic-windows.x64-11.2.0.4.0.zip到c:\oracle
3.拷贝instantclient_11_2下所有.dll文件到c:\python34\Lib\site-packages\下(根据自己的python版本拷贝到相应的site-packages文件夹下)

python连接示例代码:

# -*- coding: utf-8 -*-
import cx_Oracle

conn=cx_Oracle.connect('reporter','password','localhost:1521/ORCL')
cursor=conn.cursor()
sql="select * from test"
cursor.execute(sql)
data=cursor.fetchall()
print(data)
cursor.close()
conn.commit()
conn.close()
