I have a table with session information, with a start and stop time.
I can aggregate the information, grouping it by hour or weekday.
But, when I group it by hour and weekday, I need to also show the
average usage, so I need to figure out how many Tuesdays are contained
within 1/1/2004 - 5/1/2004, and I need to come up with a result where I
know how many of each day of the week is within that date range.
I am hoping someone may have a solution, as, once I know the number of
Tues then I can state the average number of sessions on a Tuesday at 4pm.
Thanx for any help.
