Returns the number of times a particular page (in this case .as* files) was hit, with the average, minimum, and maximum time taken, along with the standard deviation.
Statement:Notes: Query written and provided by Chevis L. Nelson (drcheeves [at] yahoo.com). Of particular note is StDev, which Chevis wrote to find the standard deviation with one query, and which has been tested against Microsoft SQL's STDEV function. Leave a comment on this query.
