I'd be interested to know what problems require the calculation of a product from each row in a query in this way.Calculating correlation statistics
It's been a long time since I did any correlations but I can't remember needing to get a product of all the numbers in a dataset, and a quick google for the formulas didn't throw up anything that required Product( X1 .. Xn)
Can you point me at more details ?
