    Log.w("Connection","open");
    Statement stmt = conn.createStatement();

    //Print the data to the console
    while(reset.next()){

                  Log.w("Data",reset.getString(2)); }

    } catch (Exception e)
    {
    Log.w("Error connection","" + e.getMessage());
    }
    }

You can connect to SQL Server databse throuh webservice.

Here is the sample code to call the webservice.

String url              = "your_webservice_URL";

 try 
 {
    HttpPost loginHttpPost   = new HttpPost(url); 
    HttpContext localContext = new BasicHttpContext();          

    MultipartEntity multipartContent = new MultipartEntity();
    multipartContent.addPart("parameter1", new StringBody(value1));
    multipartContent.addPart("parameter2", new StringBody(value2));
    loginHttpPost.setEntity(multipartContent);

    HttpClient objHttpClient = new DefaultHttpClient();
    HttpResponse response = objHttpClient.execute(loginHttpPost,localContext);
 } 
 catch (IOException e) {
     e.printStackTrace();

Make sure you set the permission in Manifest.xml file,

You can write the webservice in php or java to get this values and connect to SQL Server
