如何用Python从CSV文件创建MDB文件?

Question

我有几个csv文件，我需要转移到mdb格式。我试着把这篇文章的答案作为出发点：

How do you create a mdb database file in Python?

资料来源：

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()

但我收到了以下错误：

^{pr2}$

我需要做的就是获取一个.csv文件，并用它以mdb格式创建一个数据库。我有一些sql的经验，但没有创建access数据库文件的经验。。。。在

编辑：

我并不是说这是正确的解决方案。。。。如果你有更好的，请告诉我

编辑：在重新安装comtypes后第一次运行脚本时，我遇到以下错误：

Answer 1

试试PyPyODBC，它可以很简单：

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

运行此脚本的计算机上尚未安装Access。在

Answer 3

我建议的第一件事是尽可能升级到Python2.7。在

第二，你试过^{}吗？在

下面是一个测试脚本，它执行上面的操作：

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()
