I am trying to make connection with MS SQL with following settings
{{{
DATABASES = {
'default': {
'ENGINE': 'sql_server.pyodbc',
'NAME': 'dbName',
'USER': 'userName',
'PASSWORD': 'password',
'HOST':'hostName',
'PORT': 1433,
'OPTIONS': {
'driver': "SQL Server"
}
}
}
}}}
I had to downgrade to : pip install 'django-pyodbc-azure<1.11' which was
otherwise giving me a error of No Server/DSN found. However after
downgrading when I execute "python manage.py makemigrations" or python
manage.py runserver.
Following is my error, which I am unable to understand. Any help would be
of great help.
Thanks in advance.

Comment:
First of all `django-pyodbc-azure < 1.11` is not compatible with Django
3.0, secondly it's a 3rd-party package so it's not an issue in Django
itself, and finally, please don't use trac as a support channel.
