如何在Python中从CSV文件创建MDB文件？

Question

我有几个csv文件，想把它们转换成mdb格式。我尝试了这个帖子里的方法作为起点：

如何在Python中创建mdb数据库文件？

源代码：

from comtypes.client import CreateObject

access = CreateObject('Access.Application')

from comtypes.gen import Access

DBEngine = access.DBEngine
db = DBEngine.CreateDatabase('test.mdb', Access.DB_LANG_GENERAL)


db.BeginTrans()

db.Execute("CREATE TABLE test (ID Text, numapples Integer)")
db.Execute("INSERT INTO test VALUES ('ABC', 3)")

db.CommitTrans()
db.Close()

但是我遇到了以下错误：

Traceback (most recent call last):
  File "C:\Documents and Settings\rkelly1\Desktop\New Folder (6)\testwrite.py", line 3, in ?
access = CreateObject('Access.Application')
  File "C:\Python24\Lib\site-packages\comtypes\client\__init__.py", line 242, in CreateObject
return _manage(obj, clsid, interface=interface)
  File "C:\Python24\Lib\site-packages\comtypes\client\__init__.py", line 188, in _manage
obj = GetBestInterface(obj)
  File "C:\Python24\Lib\site-packages\comtypes\client\__init__.py", line 112, in GetBestInterface
interface = getattr(mod, itf_name)
AttributeError: 'module' object has no attribute '_Application'

我只需要把一个.csv文件拿来，创建一个mdb格式的数据库。我对sql有一些了解，但对创建access数据库文件不太熟悉……

编辑：

我并不是说这是正确的解决方案……如果你有更好的方法，请告诉我。

编辑：在新安装comtypes后第一次运行脚本时，我遇到了这些错误：

Answer 1

试试 PyPyODBC，这个用起来很简单：

import pypyodbc
pypyodbc.win_create_mdb( "D:\\Your MDB file path.mdb" )

Answer 2

你的电脑上没有安装Access这个软件，所以这个脚本无法运行。

Answer 3

首先，我建议你尽量把Python升级到2.7版本。

其次，你有没有试过win32com这个库呢？

这里有一个测试脚本，可以实现你上面提到的功能：

import win32com.client
import os

def main():
    db_path = r'C:\temp.mdb'
    if os.path.exists(db_path):
        os.remove(db_path)

    db_eng = win32com.client.gencache.EnsureDispatch("DAO.DBEngine.36")
    db = db_eng.CreateDatabase(db_path, win32com.client.constants.dbLangGeneral)

    db.Execute("CREATE TABLE test (ID Text, numapples Integer)")
    db.Execute("INSERT INTO test VALUES ('ABC', 3)")

    db.Close()


if __name__ == '__main__':
    main()
