I am stucked on this please help me

Answer 1

Try this Laravel query

DB::table('table1 as a')
->select(DB::raw('max(a.date) as max_date'))
->join('table 2 as b', 'a.id', '=', 'b.table1_id')
->where('a.publishing_time'<='2015-02-27 12:30:00')
->where(Status='1')
->get();

Answer 2

Try this..

This is laravel join query

 $resource = DB::table('table1')->join('table2', 'table1.id', '=', 'table2.table1_id')->where('table1.publishing_time','<=','2015-02-27 12:30:00')->where('table1.Status','1');

Answer 3

尝试类似：

DB::table('table a as a')->join('table b as b', 'a.id', '=', 'b.table1_id')->max('a.data as max')->where('a.publishing_time', '<=', '2015-02-27 12:30:00')->where('a.status', 1)->get();
