Avoid unnecessary loads of columns in an aggregate query that are not within an aggregate function and that are not part of the GROUP BY clause. (check-in: e15e1006 user: drh tags: trunk)

Calculate non-aggregate expressions in the SELECT list of an aggregate query that does not use min() or max() once per group, instead of once per row visited. (Closed-Leaf check-in: dce2dfbe user: dan tags: exp-agg-opt)
13:43
