So what do you do when you have to process add-hoc SPT results, where you simply don't know the structure of your results at forehand.You use Linq directly against the data. However, Rick Strahl has posted an important issue about scoping here
http://www.west-wind.com/WebLog/posts/33570.aspx and there's the whole issue of change tracking already covered in detail. That's why I keep saying "in April 2007". The behavior we see today is unlikely to be the finished result.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
