...so what makes you think I could do so here?Not sure. You DO have a love for rCTEs and I'm thinking that you'll pull a rabbit out of your hat just because you do love working with them.
Actually I think you're confusing my exploration with love.
I have kind of a fondness/hate relationship with them.
I'm fond of them because they're cool and interesting. I hate them because mostly they don't perform so well and because I am recursively challenged. And also because I haven't found that killer app yet (but will keep on looking).
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.

Since random numbers are too important to be left to chance, let's generate some![/url]
