I'm sure this is a stupidly simple issue but I just can't sort it out. I'm trying to open a local database with pyodbc but it won't let me.
The database and script are on the same path, there are no passwords. I only have one installation of Python on my system - Anaconda 3, and this is where pyodbc installed itself when I used PIP to install the Python 3.5, 64 bit whl file from Christoph Gohlke
import pyodbc
pyodbc.connect('Driver={SQL Server};Server=(local);Database=tblGrid.mdb;Trusted_Connection=yes;')
I get the following error:
pyodbc.Error: ('08001', '[08001] [Microsoft][ODBC SQL Server Driver][Shared Memory]SQL Server does not exist or access denied. (17) (SQLDriverConnect)')
Thanks
You need to use the Microsoft Access ODBC driver to open an *.mdb file.
Here is an example of connecting:
pyodbc.connect(
r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:\some\path\tblGrid.mdb')

I receive the following error when trying to connect to an MS Access DB in Python:
('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
This was the code block I used:
import pyodbc
conn = pyodbc.connect(r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ=S:\filepath\filename.accdb;')
What could be causing this error?
Cause of the error message: compatibility issues between 64bit Python and 32bit Microsoft Access. After downloading the 64bit version of Microsoft Office, there is no longer an error when creating a connection with a Microsoft Access Database.
I am getting a strange error with Python condo environments and PyODBC. I have multiple Conda environments, I am able to connect from one of the environment (from a Linux machine) to SQL Server hosted on Azure but not from the other one. Both Python environments have version 3.7.7 of Python and version 4.0.0 of Pyodbc. Code is exactly the same and connection string uses SQL Server 17 driver.
conn_str='DRIVER={ODBC Driver 17 for SQL Server};SERVER=' +server+';Authentication=ActiveDirectoryPassword;DATABASE='+database+';UID='+self.user_name+';PWD='+self.password
Error is :
pyodbc.OperationalError: ('HYT00', '[HYT00] [Microsoft][ODBC Driver 17 for SQL Server]Login timeout expired (0) (SQLDriverConnect)')
As you can see above, the issue might be DNS-related. In the
connection string, try using an IP address instead of the hostname,
or check your DNS setup.
Try downgrade to ODBC driver 13 and have a try. For that version 17
needs to be uninstalled.
Try using connect from SQL Authentication instead of Active Directory
Password.
The SQL Server ODBC drivers for Linux from Microsoft are unable to determine instance names.
I've created an Executable that utilizes pyodbc to connect to SQL Server. I need to share this executable with colleagues who have not downloaded the ODBC driver on their computers which causes the executable to fail to open.
I understand if they were to download the ODBC driver I could adjust the executable to detect the driver of the computer each time to avoid this issue. However, not everyone I share this executable with is technical so I would like to avoid having them install the ODBC driver.
Is there a way to create an executable that connects to SQL Server that does not require the user to have an ODBC driver installed on their computers?
try:
cnxn = pyodbc.connect('DRIVER={ODBC Driver 17 for SQL Server};SERVER='+server+';DATABASE='+database+';UID='+username+';PWD='+ password)
cursor = cnxn.cursor()
except:
cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER='+server+';DATABASE='+database+';UID='+username+';PWD='+ password)
cursor = cnxn.cursor()
Windows includes an ODBC driver named "SQL Server" as part of its standard installation so every Windows machine has it. It is targeted to older versions of SQL Server so it doesn't support some of the newer features in the latest releases, but if your needs are fairly basic it might suffice.
I'm trying to connect to a MS Access Database (.accdb file) via python.
I used pyodbc to do this connection:
import pyodbc
conn = pyodbc.connect("DRIVER = {Microsoft Access Driver (*.mdb, *.accdb)}; DBG=C:\\test_db.accdb")
However, I got the following error:
('IM002, '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
I went to the ODBC Data Source Administrator and when I tried to configure or remove the Driver I got the message:
Errors Found:
The specified DSN contains an architecture mismatch between the Driver and Application
I found that this error is provoked by an incompatibility between versions of Windows (windows 7 - 64bit) and Microsoft Access (Office 2010 - 32bits).
I tried to reinstall the driver several times, both with 32 and 64bit versions but the problem wasn't solved.
Could you please help me to solve this problem? Thank you in advance.
You have to make sure the Python version matches the ODBC driver version: 32-bit with 32-bit, 64-bit with 64-bit.
It looks like you have 64-bit Python / pyodbc and 32-bit MS Access.
What you'll need to do is install the 32-bit Python version, and then install pyodbc.
Good luck!
Hi everyone this is my first question on this website.
So i'm working on a Python Project at work. And i have to connect my Python/Django application to an HyperfileSQL (Windev) database to write some information on the HyperFile tables.
I've installed pyodbc library to do the job. But when i was trying to make a connection in windows Cmd, it shows me this error:
pyodbc.connect('DRIVER={HyperFileSQL};SERVER=Mondev1;DATABASE=SP_MONTREAL;UI
D=admin;PWD=')
Traceback (most recent call last):
File "", line 1, in
pyodbc.Error: ('01000', "[01000] [Microsoft][ODBC Driver Manager] The
driver doesn't support the version of ODBC behavior that the application reques
ted (see SQLSetEnvAttr). (0) (SQLDriverConnect); [01S00] Invalid connection string attribute (0)")
I really don't understand why the connection failed. Anyone has any idea.
Note: Sorry about my poor english level i'm french :).
If you want to access hyperfile through odbc you need the driver odbc for hyperfilesql.
You need to buy it. Then install it and configure an odbc connection to your database. Here is the documentation :
http://doc.pcsoft.fr/fr-FR/?3044179
Then you will be able to access with python to your database through the odbc driver for hyperfilesql.
Hope it will help.
