...so what makes you think I could do so here?

For the simple task of sorting in the correct order, we'll use the "Hierarchical Path" method. To build it, we'll use a "Recursive CTE". Look that up in Books Online for a better understanding of them. I will tell you right now that they are NOT a panacea. Hierarchies are one of the few places where I don't mind the use of recursive CTE's because they're normally RBAR code. In the example that follows, the recursive CTE is "layered" or (as Celko calls it), "lasagna" code. It processes a full set (one full level) of information for each iteration which makes it non-RBAR code. It's still a bit slower than a more lengthy method but it takes a huge hierarchy to really appreciate the difference so the recursive CTE is usually good enough.
