I used this but only on my Test Box, With small data. I think no problem will be there if we will use indexes for both depth first search and breadth first search as per the requirement.

Thanks for the feedback. I appreciate it.

As a bit of sidebar, there's almost never a performance problem with small data. I have code that will build a million row Adjacency List and to truly answer the question, I guess I'm just going to have to test it and find out for sure. Your response also reminds me to test for resources used by indexes no matter what method is used. Thank you.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair
