The aggregate functions minimum and maximum allow only numeric values.
I would need this aggregate functions for date fields too.
While your suggestion makes absolute sense, a workaround for the time being would be to use something like
JulianToDate(Minimum(DateToJulian(Orders.OrderDate)))
i.e. convert the date to a double, use the aggregate function on the set of doubles and then convert the result back to a date. Works like a charm :).
