Hi DwainI'm enormously grateful for the code you've put up. I'll test yours and Chris's and see what I can learn from them. I'll post back my observations after some time for reflection...(he said clinging for dear life to the learning curve)
I'd be interested to know how the 2 compare on performance. I'm not so sure mine will stand up, primarily because of the adaptations I had to make to be SQL 2005 compatible.
Hopefully we'll see.
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
