so far I have been testing my sql statements in the sql ineractive query which has helped.....but I am trying to figure out how to return a calculated field, IE: I can get the sum of extended invoice price and the sum of the extended cost, but if I want the difference of the two or margin, is it possible to have the sql query just return it as well? Or would I be better off doing that manually? The reason I ask is I would like to rank the records high to low on margin. If you bought, it was hauled by a truck - somewhere, sometime.
