Question

After some anguish trying to connect to a SQLServer database with Ruby, I finally discovered TinyTDS and it’s fantastic.

However, it requires a username and password to talk to the database. In C# tests in the past, we’ve used SSPI to supply this, so that any tester can pick up a script and run it and it’ll use their Windows Authentication details.

I can’t find a way to do this with TDS (beginning to suspect it’s not possible with the current version) and hoping someone might prove me wrong, or have another suggestion?

Cheers.

Answer 1

Found the solution.

My install of tiny-tds was version 0.51.

The latest version has SSPI, and so to get that:

gem install tiny_tds --version ">= 0.6.0.rc1"

This comes with no need to specify a username/password and use SSPI by default.

So as an example:

require  'tiny_tds'

    sql = "SELECT name from sys.databases"
    client = TinyTds::Client.new(:dataserver => "myserver", :database => "mydatabase")
    result = client.execute(sql)
    results = result.each(:symbolize_keys => true, :as => :array, :cache_rows => true, :empty_sets => true) do |rowset| end
    #THIS IS TO OUTPUT IT TO THE CONSOLE
    for i in (0..result.fields.length)
      printf("%14s", result.fields[i])
    end
    for j in (0...result.affected_rows)
      puts ""
      for i in (0...result.fields.length)
        printf("%14s",results[j].at(i))
      end
    end

Will print out a list of the database names, using SSPI to access the database.
