Fascinating article! I have a couple of naive questions about the following bit of G code:

Adjacency (NodeID, ParentID) as -- Adjacency Query

Wayne, yes, thank you. That explains it completely. So, using your example of a time "80101", the code would (working from the inside out) transform it thusly:

80101 (original)

10108 (reversed)

10:108 (stuff...

Sorry for the late reply, I didn't get the usual email notifying me of a new post.

Thanks, G! I think that did it! I'd love to see your "outer apply...

1. Craig, can I have an autographed photo of your brain for Chistmas?

2. This is totally cool. I'm trying to figure it all out. I think I'm doing pretty well....

Awesome, got it. Thanks! I've taken up a good deal of your time today, Craig!

Okay, I think this is starting to make sense now. Contiguous is defined here as "at least one date entry per day during a range". Okay. And now the rest...

I'm sorry, CirquedeSQLeil, but I literally don't even understand most of what your last post was asking. My computer has 2GB memory. I have a few test/sample databases including AdventureWorks...

Yeah, it's just a super-dinky setup on my home computer with absolutely nothing hitting it. Thanks!

I have 2GB. I have confirmed that sql server is the process that is performing constant activity on my hard drive(s), but beyond that I don't know what else to...
