As far as i know there is no function in delphi to get the sum automatically.
Yoy can use SQL with a query component or use quickreport expressions to get the sum of any numeric field

Let say, I do "select sum(area * population) from country" in TQuery !
But, if I have a calculated field, called AP, in TTable now and I want to get the sum of this calculated field ?
So, I hope to know how can I get this value !
