Here are the instruction on how to setup the dsn in linux using unixODBC and freeTDS http://lucasmanual.com/mywiki/TurboGears#head-bab4c0bbfb83fb7c376a8a0cb68841c4e76ad130 Now I tried connecting to mssql via: ------------------------0.3------------------------ db = sqlalchemy.create_engine('mssql://user:[EMAIL PROTECTED]/dbname', module=adodbapi) db = sqlalchemy.create_engine('mssql://user:[EMAIL PROTECTED]/dbname', module=adodbapi) Traceback (most recent call last): File "<stdin>", line 1, in ?

Do you guys know what is the connection string for adodbapi so I can try to connect just by adodb Thanks, Lucas --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
