python - Pyodbc 错误 - Python 到 MS Access

Question

我在 Windows 7、Python 2.7 和 Microsoft Access 2013 上运行。

当我尝试运行时:

import pyodbc
conn_string = '''
DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};
UID=admin;
UserCommitSync=Yes;
Threads=3;
SafeTransactions=0;
PageTimeout=5;
MaxScanRows=8;
MaxBufferSize=2048;
FIL=MS Access;
DriverId=25;
DefaultDir=C:\Users\jseinfeld;
DBQ=C:\Users\jseinfeld\Desktop\Databasetest1.accdb;
'''
connection = pyodbc.connect(conn_string)

我收到以下错误消息:

Error: ('HY000', "[HY000] [Microsoft][ODBC Microsoft Access Driver]General error Unable to open registry key Temporary (volatile) Ace DSN for process 0x29dc Thread 0x113c DBC 0x8a3ed48

Jet'. (63); [HY000] [Microsoft][ODBC Microsoft Access Driver] Not a valid file name. (-1044)")

我知道有很多关于 Pyodbc 和 MS Access 的问题。我已经执行了以下操作:

1) 确保我有 64 位 Python 和 64 位 MS Access

2) 允许帐户 Access HKEY_LOCAL_MACHINE\SOFTWARE\ODBC 注册表项

Error in opening an Access database in python

"General error Unable to open registry key Temporary (volatile) ..." from Access ODBC

3) 试图确保我有一个有效的连接字符串 https://stackoverflow.com/questions/6469545/python-connecting-to-a-database-with-pyodbc-not-working#=

4) 当我尝试运行这段代码时，Access 数据库没有打开。我已重新启动计算机，但仍收到此错误。

如果我可以尝试任何其他操作，请告诉我。

Answer 1

从一个只有 DRIVER 和 DBQ 属性且没有嵌入式换行符的简单连接字符串开始......

conn_string = r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:\Users\jseinfeld\Desktop\Databasetest1.accdb;'

一旦您获得最简单的连接字符串，您就可以根据需要添加和测试其他连接属性。
