What's causing 'unable to connect to data source' for pyodbc?

Question

I\'m trying to connect to an MSSQL database from python on Linux (SLES).

I have installed pyodbc and Free TDS. From the command line:

tsql -H server          


        

Answer 1

This worked for me, not sure but thought that it might help someone

run below command to find which version of odbcinst and isql you are using

 which odbcinst

 which isql

Then run $ odbcinst -j to find which odbc.ini and odbcinst.ini is getting used.

In odbcinst.ini add

[FreeTDS]
Description=FreeTDS Driver for Linux & MSSQL
Driver=/usr/local/lib/libtdsodbc.so
Setup=/usr/local/lib/libtdsodbc.so
UsageCount=1

And in odbc.ini configure your server as

[YOUR_SERVER]
Driver = FreeTDS
Servername = 
Database = 

I found some good description at https://docs.snowflake.net/manuals/user-guide/odbc-linux.html#unixodbc
