Laravel select count in select
You should use selectRaw() instead of select() and separate other parts of query to related methods:
$pois = DB::select(DB:raw("*, (SELECT count(*) from stamps WHERE pois.id = stamps.poi_id) nbr_stamps")) ->from('pois') ->orderBy('nbr_stamps', 'DESC') ->limit(3);Read the Query Builder documentation.
@thanks to limonte for the documentation link, i found the right way to write to select raw, here the solutions :
$pois = DB::table('pois') ->select(DB::raw("*, (SELECT count(*) from stamps WHERE pois.id = stamps.poi_id) nbr_stamps")) ->orderBy('nbr_stamps', 'DESC') ->take(3) ->get();have a nice day ;)
