[英]how to create a mdb file from a csv file in python?
I have several csv files that I need to transfer over to mdb format. 我有几个csv文件,我需要将其转换为mdb格式。 I tried the answer in this post as a starting point:
我以这篇文章为起点尝试了答案:
How do you create a mdb database file in Python? 如何在Python中创建mdb数据库文件?
Source: 资源:
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()
But I received the following errors: 但是我收到以下错误:
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'
All I need to do is take a .csv file, and create a database with it in mdb format. 我需要做的只是获取一个.csv文件,并以mdb格式创建一个数据库。 I have some experience with sql but not with creating access data base files....
我对sql有一些经验,但是对创建访问数据库文件没有经验。
EDIT: 编辑:
I am not proposing that this is the right solution.... If you have a better one please let me know 我并不是说这是正确的解决方案。...如果您有更好的解决方案,请告诉我
EDIT: The first time the script runs after a fresh install of comtypes I get these errors: 编辑:脚本第一次全新安装后运行,我得到以下错误:

First thing I would suggest is upgrading to python 2.7 if at all possible. 我建议的第一件事是尽可能升级到python 2.7。
Second, have you tried win32com
? 第二,您尝试过
win32com
吗?
Here's a test script that does what you have above: 这是一个测试脚本,可以完成上面的操作:
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()
您尚未在运行此脚本的计算机上安装Access。
Try PyPyODBC, it can be as easy as: 尝试使用PyPyODBC,它很容易:
import pypyodbc
pypyodbc.win_create_mdb( "D:\\Your MDB file path.mdb" )
