问题 I currently have a function: Score::whereIn('site_id', $sites) ->where('type', 1) ->avg('score'); But at the moment, as you can see, it averages out amongst all results within the Scores table. I want to only average out against the most recent row of each $site_id (the table may not have all $site_id's in the results though).

Is their any way to tell Laravel not to do this on that particular model? 回答1: As suggested earlier, renaming your column would be a good idea, because it's a reserved keyword in most database servers.
