Goal: Connect to MSSQL using FreeTDS / ODBC in Python.

Host: Ubuntu 11.10 x86_64

Install:

sudo apt-get install freetds-dev freetds-bin unixodbc-dev tdsodbc
pip install pyodbc sqlalchemy

In /etc/odbcinst.ini:

[FreeTDS]
Description=FreeTDS Driver
Driver=/usr/lib/odbc/libtdsodbc.so
Setup=/usr/lib/odbc/libtdsS.so

hello_pyodbc.py

"Proof connection at pyodbc level."
# Test pyodbc connection. Result is 42.
# Note parameters in connection string, <PARAMETER>.

import pyodbc


conn = pyodbc.connect('DRIVER=FreeTDS;SERVER=<IP_OR_HOSTNAME>;PORT=1433;DATABASE=<DATABASE_NAME>;UID=<USERNAME>;PWD=<PASSWORD>;TDS_Version=8.0;')
cursor = conn.cursor()
for row in cursor.execute('select 6 * 7 as [Result];'):
    print row.Result

hello_sqlalchemy.py

"Proof connection at SQLAlchemy level, on top of pyodbc."
# Test SQLAlchemy connection. Result is 42.
# Note parameters in connection string, <PARAMETER>.

import urllib

from sqlalchemy import create_engine


engine = create_engine('mssql+pyodbc:///?odbc_connect=' +
    urllib.quote_plus('DRIVER=FreeTDS;SERVER=<IP_OR_HOSTNAME>;PORT=1433;DATABASE=<DATABASE_NAME>;UID=<USERNAME>;PWD=<PASSWORD>;TDS_Version=8.0;')
)
for row in engine.execute('select 6 * 7 as [Result];'):
    print row.Result

Good day.

I'm trying to connect my raspberry pi 3 to my Azure Sql db.
I came across FreeTDS and it looks promising. I tried the steps above with no luck.

I'm running Raspberry Pi Os(32 - bit) with Debian 11.

Error im currently at is: conn = pyodbc.connect('DRIVER=FreeTDS;SERVER=cmpg-sql-db.database.windows.net;PORT=1433;DATABASE=CMPG_323;UID=Beertjie007;PWD=Beertjie@@7;TDS_Version=8.0;')
pyodbc.OperationalError: ('08001', '[08001] [FreeTDS][SQL Server]Unable to connect to data source (0) (SQLDriverConnect)')

I'm also trying to change the .ini file as prescribed with no luck maybe that is my problem but i cant due to access denied.

Is there any ways to approach this differently or use another way to connect from Raspberry pi to azure.

Sorry I'm new to this and could use all the help and detail.

Please help........!!!!
