Re: Rails and MSSQLserver: Anyone had success with Microsoft Sqlserver ?

I have successfully implemented the Depot application from the Agile Web
Development with Rails with SQLServer using the sqlserver adapter which
requires an installation of the ADO module of DBI (iirc).

Your naming of the id column may be an issue. My suggestion is to try to get
a simple app working first to isolate the db connection issues you are
having.

HTH,
