Pyodbc和MS Access 2010连接错误 [英] pyodbc and ms access 2010 connection error
问题描述
如何使用pyodbc访问Microsoft Access 2010数据库(accdb)? 以前,我使用了mdb数据库,该数据库在连接字符串为
How can I access my Microsoft Access 2010 database (accdb) with pyodbc? Before, I used an mdb Database, which worked fine with the connection string being:
ODBC_CONN_STR = 'DRIVER={Microsoft Access Driver (*.mdb)};DBQ=%s;' % ACCESS_DATABASE_FILE
现在我使用:
import pyodbc
ACCESS_DATABASE_FILE = "PSA_TEST.accdb"
ODBC_CONN_STR = 'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=%s;' % ACCESS_DATABASE_FILE
conn = pyodbc.connect(ODBC_CONN_STR)
我得到的错误是: pyodbc.Error:('HY000','[HY000] [Microsoft] [ODBC-TreiberfürMicrosoft Access] KeinzulässigerDateiname.(-1044)(SQLDriverConnect)')
The error I get is: pyodbc.Error: ('HY000', '[HY000] [Microsoft][ODBC-Treiber für Microsoft Access] Kein zulässiger Dateiname. (-1044) (SQLDriverConnect)')
翻译为文件名不可接受". 我找到了一个相关问题,但是答案对我不起作用(使用pyodbc连接到MS Access 2007(.accdb)数据库).我根据以下输出使用32位python:
Which translates to "the filename is not acceptable". I found a related question, but the answer does not work for me (Connecting to MS Access 2007 (.accdb) database using pyodbc). I use 32 bit python according to the output of:
python -c 'import struct; print struct.calcsize("P") * 8'
和MS Access 32位.
and MS Access 32 bit.
- 以防万一,我用 os.path.isfile(ACCESS_DATABASE_FILE)检查该文件确实存在
- 可以使用Access打开文件
- 使用新的连接字符串打开以前的mdb文件会给出相同的错误消息,这不是预期的行为
- Just in case, I check with os.path.isfile(ACCESS_DATABASE_FILE) that the file actually exists
- the file can be opened with Access
- opening the previous mdb file with the new connection string gives the same error message, which afaik is not the expected behavior
推荐答案
好,很抱歉回答我自己的问题,但是通过反复试验,我了解到,如果您使用第二个连接字符串,则需要指定绝对路径名:
Ok, sorry to answer my own question, but by playing around, I learned that you need to specify the absolute path name if you use the second connection string:
ACCESS_DATABASE_FILE = 'C:\\path\\to\\PSA_TEST.accdb'
ODBC_CONN_STR = 'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=%s;' % ACCESS_DATABASE_FILE
然后,它甚至可以与accdb文件以及mdb文件一起使用.
Then it even works with the accdb file, as well as with the mdb file as expected.
