有同样的问题 - 转义访问位置中使用的反斜杠db

>>> conn = pyodbc.connect（Driver = {Microsoft Access Driver（* .mdb，* .accdb）}; DBQ = C：\\access\\site_be.accdb;）


工作方式为

>>> conn = pyodbc.connect（Driver = {Microsoft Access Driver （* .mdb，* .accdb）}; DBQ = C：\access\site_be.accdb;）


给我错误
Jet'。（63）; [HY000] [Microsoft] [ODBC Microsoft Access驱动程序]不是有效的文件名。 （-1044））


希望有帮助..

I am trying to connect to an Access 2007 database with the following connection string.

conn = pyodbc.connect("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=<C:\Users\JSeinfeld\Desktop\Backup databases\Database_6.7.accdb>;")

I get this error:

Traceback (most recent call last):
File "", line 1, in conn = pyodbc.connect("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=;")

Error: ('HY000', "[HY000] [Microsoft][ODBC Microsoft Access Driver]General error Unable to open registry key Temporary (volatile) Ace DSN for process 0x167c Thread 0x1568 DBC 0x1c67a5c

There is another question like this on SO, but there was a 32/64bit compatibility issue which I do not have. There doesn't seem to be a good answer for this question, but hopefully someone can help me connect to my database because I don't know of any other way to query or write data to Access 2007 with python.

Thanks

Had the same issue - it was a simple case of escaping the backslash used in the location of the access db

>>> conn = pyodbc.connect("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:\\access\\site_be.accdb;")

worked as whereas

>>> conn = pyodbc.connect("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:\access\site_be.accdb;")

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

Hope that helped..
