I have several years of data and temperature in one table. I want to calculate a cumulative temperature sum which I've done simply as A.CumulativeTemp= cumsum(A.Temp);
My question is, how can get a cumulative temp for each year, i.e. so it gives a cumulative temperature for the entire 2016, then starts again at zero in the same column and does the same for 2017 and so on?
Kind regards, Wendy
