Can't open lib 'ODBC Driver 13 for SQL Server'? Sym linking issue?

When I try to connect to a sql server database with pyodbc (on mac):

import pyodbc

server = '####'
database = '####'
username = '####@####'
password = '#####'
driver='{ODBC Driver 13 for SQL Server}'

pyodbc.connect('DRIVER='+driver+';SERVER='+server+';PORT=1443;DATABASE='+database+';UID='+username+';PWD='+password)

I get the following error:

Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib 'ODBC Driver 13 for SQL Server' : file not found (0) (SQLDriverConnect)")

When I path in the actual driver location:

driver='/usr/local/lib/libmsodbcsql.13.dylib'

It starts working!

My odbcinst.ini looks like this:

[ODBC Driver 13 for SQL Server]
Description=Microsoft ODBC Driver 13 for SQL Server
Driver=/usr/local/lib/libmsodbcsql.13.dylib
UsageCount=1

How can I get my reference to driver='{ODBC Driver 13 for SQL Server}' to start working again?

I initially used this guide to install the driver. And I'm using anaconda on Mac Sierra if that helps?

Running:

odbcinst -j

It yielded:

unixODBC 2.3.4
DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
FILE DATA SOURCES..: /etc/ODBCDataSources
USER DATA SOURCES..: /Users/emehex/.odbc.ini
SQLULEN Size.......: 8
SQLLEN Size........: 8
SQLSETPOSIROW Size.: 8

Instead of copying the files to the /etc/ directory (not sure why unixODBC thought they were there) I created a symbolic link to each file:

sudo ln -s /usr/local/etc/odbcinst.ini /etc/odbcinst.ini
sudo ln -s /usr/local/etc/odbc.ini /etc/odbc.ini

This solved the problem.

Breastbeating answered 14/6, 2017 at 13:52 Comment(8)

Good solution - to answer your question. unixODBC defaults to search for odbc.ini and odbcinst.ini in /etc. It will also check the user's home directory for .odbc.ini and .odbcinst.ini. (FreeTDS does the same with freetds.conf / .freetds.conf, for the record.) – Felonry 16/6, 2017 at 20:37

This works (although I had to uninstall and reinstall the driver learn.microsoft.com/en-us/sql/connect/odbc/linux-mac/…), but there's a small typo: sudo ln -s /usr/local/etc/odbc.ini /etc/odbc.ini – Delenadeleon 25/1, 2018 at 19:34

This error can also occur if you have updated to a new version of the driver. If the filed are present check the content of /etc/odbcinst.ini ie: $ cat /etc/odbcinst.ini [ODBC Driver 17 for SQL Server] Description=Microsoft ODBC Driver 17 for SQL Server Driver=/opt/microsoft/msodbcsql/lib64/libmsodbcsql-17.0.so.1.1 UsageCount=1 Then update the content of your scipt to use the new driver. In this case the driver was updated from version 13 to version 17. I suggest you add this information for completeness. – Orji 16/2, 2018 at 16:37

ln: failed to create symbolic link '/etc/odbcinst.ini': File exists – Eighteenmo 17/2, 2019 at 18:41

file exists error means odbcinst.ini already exsits in the /etc folder. rename the file to odbcinst.ini_old and try the ln -s command again and see if that works – Flotow 18/4, 2020 at 20:21

It seems better to me to change the location.... #41585774 – Alaric 19/10, 2021 at 10:51

@Delenadeleon This should be its own answer imo. This worked for me although somewhat lazy that microsoft does not detect your ubuntu version in the script. – Waggle 25/10, 2021 at 19:49

Note that for M1 macs, the above symlinks might be invalid. This is because the homebrew directory on M1s is /opt/homebrew instead of /usr/local. Thus the paths should be adjusted accordingly. – Calyptrogen 6/4, 2022 at 14:37

In my case, I have a Mac OS and the following commands fixed the problem:

brew tap microsoft/mssql-release https://github.com/Microsoft/homebrew-mssql-release
brew update
brew install msodbcsql mssql-tools

Note 1: It might be necessary that you need to install unixodbc in advance to msodbcsql and mssql-tools as the following:

brew install unixodbc

Note 2: If you dont have already brew, the Missing Package Manager for macOS, then you can install it from here: https://brew.sh/

Note 3: You can verifiy your installation as @emehex already mentioned above with the following commands:

odbcinst -j

sudo ln -s /usr/local/etc/odbcinst.ini /etc/odbcinst.ini
sudo ln -s /usr/local/etc/odbc.ini /etc/odbc.ini

Thank you very much for this quick fix (Y) – Semiramis 15/11, 2018 at 14:51

I also had to add driver details in the connection settings

connection = pyodbc.connect("Driver={ODBC Driver 13 for SQL Server};"                         "Server=someHost;"                         "Database=dbname;"                         "uid=SA;pwd=passowrd")

– Semiramis 16/11, 2018 at 15:40

This is outdated as brew does not support the --no-sandbox optin anymore (since start of 2019). The implemnented fix is to drop that option. see github.com/Microsoft/homebrew-mssql-release/issues/29 – Flowing 2/5, 2019 at 8:21

@A.Rabus Thanks for the comment. The post is updated with your suggestion. – Anticipation 2/5, 2019 at 8:34

We have a presentation in a few hours and my program won't work on mac. This saved our lives. – Vallecula 24/6, 2020 at 4:29

@ReneB. when I run brew install unixodbc i get the following error: "Error: No similarly named formulae found. Error: No available formula or cask with the name "unixodbc". Could this be because I am running macOS Big Sur? – Shackle 25/3, 2021 at 4:23

Thank you @ReneB., this worked great. I found my code preferred version 17 as opposed to 13. – Byelection 26/8, 2021 at 10:11

In my case, I had to change the pyodbc database driver string to
driver='{ODBC Driver 17 for SQL Server}'

actually, in my python code pyodbc was expecting ODBC Driver 13 but, as the ODBC Driver version was updated (because of ubuntu update) to current version ODBC Driver 17, the problem had occurred.

In my case, I fixed the problem with three steps as follow:

# Step1: install unixodbc 
brew install unixodbc

# Step2: install Microsoft ODBC Driver for SQL Server on MacOS

brew tap microsoft/mssql-release https://github.com/Microsoft/homebrew-mssql-release
brew update
brew install msodbcsql mssql-tools

# Step3：verify odbcinst configuration path is correct

odbcinst -j

sudo ln -s /usr/local/etc/odbcinst.ini /etc/odbcinst.ini
sudo ln -s /usr/local/etc/odbc.ini /etc/odbc.ini

I was building a custom image on top of Python and this is the configuration that made it work:

FROM python:3.8 as pyodbc

COPY . /app
WORKDIR /app

# Required for msodbcsql17 and mssql-tools
RUN curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -
RUN curl https://packages.microsoft.com/config/debian/10/prod.list > /etc/apt/sources.list.d/mssql-release.list
RUN apt-get update

# Key might change in the future, replace with new one on the logs
RUN apt-key adv --keyserver keyserver.ubuntu.com --recv-keys BA6932366A755776
RUN apt-get update
RUN apt-get install -y software-properties-common
RUN add-apt-repository ppa:deadsnakes/ppa
RUN apt-get update

RUN ACCEPT_EULA=Y apt-get install -y msodbcsql17 mssql-tools
RUN apt-get install unixodbc-dev

RUN pip install pipenv
RUN pipenv install --system --deploy

CMD [ "python" , "__init__.py"]

apt-get update

apt-get -y install unixodbc-dev
sudo apt-get install python3-pip -y
pip3 install --upgrade pyodbc

Use above steps to istall the odbc driver correctly and everything will fall in place.

I've tried to establish a connection to a remote MS SQL Server deployed on a (Windows) machine from an external (Linux) machine. It took me some time to realise you need to first install the drivers on the machine that tries establish connection (i.e. Linux in my case)!

If you're using macOS/Linux what you need to do is to simply Install the Microsoft ODBC Driver for SQL Server on Linux and macOS and then follow instructions on Connecting to databases for your particular OS.

that "Microsoft ODBC Driver for SQL Server for linux/macos" link was helpful, thanks – Somerset 21/1, 2020 at 11:3

I have to add that if you are using a different driver (FreeTDS) and in your connection string you omit to mention it, it will default to driver='{ODBC Driver 17 for SQL Server} or something like like that.

So the solution is not to forget driver, you DB settings will look like this: 'default': { 'ENGINE': 'sql_server.pyodbc', 'HOST': '127.0.0.1', 'NAME': 'mydb', 'PORT': '1433', 'USER': 'sa', 'PASSWORD': '*****', 'OPTIONS':{ 'driver': 'FreeTDS', 'host_is_server': True, } }

I was struggling with a similar issue.

Firstly, I was following this instruction:

I thought the error was in that I used driver 17 and not driver 13 - as per the connection string visible in the Azure Portal.

After playing around with it for a long time, getting this error for driver 13: " pyodbc.Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib '/usr/local/lib/libmsodbcsql.13.dylib' : file not found (0) (SQLDriverConnect)") "

and getting a timeout error for driver 17.

I finally found the solution in this hack. The problem was OpenSSL where two versions confused up.

I'm running the app in a vertual environment in VS Code on my Mac and deploying it to Azure Web App.

I simply built image top of python:3.7-alpine

FROM python:3.7-alpine

COPY . /app/.
WORKDIR /app

# Install curl
RUN apk add --no-cache curl
RUN apk update && apk add curl

# Install the Microsoft ODBC driver Linux.Follow the mssql documentation: https://learn.microsoft.com/en-us/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server?view=sql-server-ver15
RUN curl -O https://download.microsoft.com/download/e/4/e/e4e67866-dffd-428c-aac7-8d28ddafb39b/msodbcsql17_17.8.1.1-1_amd64.apk
RUN curl -O https://download.microsoft.com/download/e/4/e/e4e67866-dffd-428c-aac7-8d28ddafb39b/mssql-tools_17.8.1.1-1_amd64.apk

# Install the package(s)
RUN apk add --allow-untrusted msodbcsql17_17.8.1.1-1_amd64.apk
RUN apk add --allow-untrusted mssql-tools_17.8.1.1-1_amd64.apk

# Install other libs
RUN pip install --upgrade pip
RUN pip install -r requirements.txt

RUN apk add python3 python3-dev g++ unixodbc-dev
RUN python3 -m ensurepip
RUN pip3 install --user pyodbc

# Run script
ENTRYPOINT [ "python", "-u", "run.py"]

When setting connection inside the code, you need to specify the driver version that you've installed. For instance in my case:msdobcversion=17 so driver should be DRIVER={ODBC Driver 17 for SQL Server}

# Make connection
server = os.environ["server"]
database = os.environ["database"]
username = os.environ["UID"]
password = os.environ["PWD"]
cnxn = pyodbc.connect('DRIVER={ODBC Driver 17 for SQL Server};SERVER='+server+';DATABASE='+database+';UID='+username+';PWD='+ password)

Installation that worked on the Ubuntu 18.04. I'm not sure if two of the ./bash_profile and ./bashrc exports are needed but I didn't have time to check.

sudo apt-get update
ACCEPT_EULA=Y sudo apt-get -y install msodbcsql17 mssql-tools
echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profile \
echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc \
sudo apt-get -y install unixodbc libc6 libstdc++6 libkrb5-3 libcurl3 openssl debconf unixodbc unixodbc-dev

Then as a driver in connection use ODBC Driver 17 for SQL Server which is matching the current Azure version.

I know everyone had the same stupid error ones: but I remind, I spent 30 mins just reading this branch... error was odd space at the end of connection string

     SQLALCHEMY_DATABASE_URI: str = "mssql+pyodbc://sa:tt@localhost:1433/babylon_pacemaker?Trusted_connection = no&driver=ODBC+Driver+17+for+SQL+Server " - odd space :(

Funny that Alembic works well, but SQLAlchimy has an error.

In my case after running below commands with sudo user, i used DRIVER={ODBC Driver 17 for SQL Server}, which resolved my problem.

Users on Arch Linux can install specific packages from the AUR

1. aur/msodbcsql17 17.10.1.1-1 (+3 0.66) 
Microsoft® ODBC Driver 17 for SQL Server®

2. aur/msodbcsql 18.0.1.1-1 (+24 0.38)
Microsoft® ODBC Driver 18 for SQL Server®

I had same problem and I sorted with following command:
sudo ln -s /usr/local/etc/odbcinst.ini /etc/odbcinst.ini.
sudo ln -s /usr/local/etc/odbc.ini /etc/odbc.ini.
after them if you run the file you should not get the same error.
