Re: Query for sum of a column from this time last year
To retrieve the sum result from last year at this date, you need either (i) to have saved that sum result last year, or (ii) a table that implements point-in-time architecture, ie it guarantees that no stored value is ever edited or deleted without saving the pre-edit or pre-deletion value.
