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

I had the same problem and I found out that it was missing the TDS_Version parameter in the call to connect(). The following code works for me to connect to an instance of MS SQL Server 2008:

import pyodbc

driver = '/opt/local/lib/libtdsodbc.so' # Change this to where FreeTDS installed the driver libaray!

conn = pyodbc.connect(
    driver = driver,
    TDS_Version = '7.2', # Use for
    server = '',
    port = 1433,
    database = '',
    uid = '',
    pwd = '')
