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

问题:

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?

回答1:

Running:

odbcinst -j 

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/odbci.ini 

This solved the problem!

回答2:

In my case, I have 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 was occurred.
