Using this technique:
Report.where("unit_id=? AND id >= ? AND id <= ?", unit_id, report1,
report2).sum('distance')
was ultimately the best solution for me, because using find_by_sql and
then calling sum on it would behave unexpectedly, like sometimes the
sum would have to be invoked twice: find_by_sql(...).sum.sum
And I replaced id with time to select within time frame
