Jeff, I had to rate this article 5 stars, because that's as high as the ratings allow. It deserves a 15!
BTW, I'm aghast --- you've actually used a SQL CLR now! 😀 It would be nice if we could get Paul to contribute it, and to have it added to the resources of this article.
Again, excellent job. Extremely well done, and extremely thorough. Thank you so much for this article, and for the new DelimitedSplit8K function.
