dwain, Jeff said this was the expected behaviour in the article:The following code generates a million rows of random integers (the SomeRandomInteger column) with possible values from 400 to 500 and float values (the SomeRandomFloat column) from 400 to 500.999999999999 in just over 4 seconds on my 10 year old, single CPU computer.
Ooops. Must'a missed it. Anyway it is clear now. Thanks.
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.
