python连接Oracle数据库的代码，需要引用cx_Oracle库

#coding=UTF-8 
    import cx_Oracle 
    def hello(): 
        '''Hello cx_Oracle示例： 
        1)打印数据库版本信息. 
        2)查询表数据.''' 
        conn = cx_Oracle.connect("obs61","obs61","tx8i.hp") 
        cur = conn.cursor() 
        try: 
            print "Oracle Version:%s" % conn.version 
            print "Table SUB_POLICY rows:" 
            cur.execute('select * from wlan_future_event') 
            for row in cur: 
                print row 
        finally: 
            cur.close() 
            conn.close() 
    hello()
