在Oracle 10上使用预取的Python

有没有办法在这个程序中集成预取？我的目标是尽快从数据库中获取数据

正在获取10000行

cursor.arraysize=10000

import cx_Oracle
import wx

print "Start..." + str(wx.Now())

base = cx_Oracle.makedsn('xxx', port, 'yyyy')

connection = cx_Oracle.connect(user name, password, base)

cursor = connection.cursor()

cursor.execute('select data from t_table')

li_row = cursor.fetchall()

data = []

for row in li_row:

    data.append(row[0])

cursor.close()

connection.close()

print "End..." + str(wx.Now())

print "DONE!!!"
