mdb格式文件可以通过mdbtools工具将内中包含的每张表导出到csv格式文件。由于access数据库和postgresQL数据库格式上会存在不通性，所以使用python的文件处理，将所得csv文件修改成正确、能识别的格式。

导入脚本说明（此脚本运行于linux）：

1.apt-get install mdbtools,安装mdbtools工具

2.将mdb 文件拷贝到linux虚拟机中，修改脚本中mdb文件目录'dir'

3.修改服务器及数据库配置

4.执行脚本

复制代码 代码如下:

import re
import psycopg2
import csv

dir = r'/home/kotaimen/mdb_file/'
mdb_tbl_dic = {}

1.制作mdb文件中所包含TABLE的create脚本

make_create_sql()  
#2.修改掉create脚本中的不合法字符  
modefy_create_sql()  
#3.将mdb中各表导出到csv文件中  
make_insert_csv()  
#4.修改csv脚本首行，改成copy形式
