This is an excellent follow up to the first article. In the example for displaying a comma separated values list of all the test scores for each student, could you have also used the coalesce function to prevent the first comma in the output?

Great article series, Paul!
It was a pleasure being selected to get a preview and to give some thoughts/comments.
Let's see how long it takes until I have referenced those two articles more often then I did Jeffs CrossTab/DynamicCrossTab :-D

Paul, Wow, thanks for these two articles they really helped me understand better use of APPLY. Now if I can just remember all of that I think I will use it a lot more.

Thanks again!

Mike and Green Clay:

Yes the ORDER BY in the CROSS JOIN example should be as you say - oddly it is only the image in the article that has this typo, the downloadable code is correct.

Thank you Paul!

You post it just when I needed to use the CROSS APPLY to process a XML file :-)

Nice article, Paul. With this and the previous one I think I'm beginning to understand apply (a feature I haven't yet used, but probably will sometime soon now that you have shown me how it can be used to express things in a nice clean modular fashion).
