Answer 1

You need to use DB::raw() in where to tell the query builder that it is not column name it is data manipulation in query,

$oncoming_events = DB::table('events')->select(DB::raw('count(*) as numOfOncomingEvents, MONTH(begin_date)'))->where(DB::raw('YEAR(begin_date)'), '=', 'YEAR(CURDATE())')->orWhere(DB::raw('YEAR(begin_date)'), '=', 'YEAR(CURDATE()) +1')->groupBy(DB::raw('MONTH(begin_date)'))->get();
