How to get other column value in different table into the query?

I had searching application, finding personal information which had been filtered by some criteria (category, years of experience etc)

I had problem with the last filter, 'tempoh perkhidmatan by negeri'. I need to calculate the number of working experience by state(negeri). For example, when searching for people of 5 years in the state(negeri) 'x', the sql will sum years of experience of each person in the state selected.

This is the full code of SQL searching by criteria:

   $query = DB::table('itemregistrations')
                ->join('sections', 'itemregistrations.SectionID', '=', 'sections.SectionID')
                ->join('categories', 'itemregistrations.CategoryID', '=', 'categories.CategoryID')
                ->join('operasi', 'itemregistrations.OperasiID', '=', 'operasi.OperasiID')
                ->join('negeri', 'itemregistrations.NegeriID', '=', 'negeri.NegeriID')
                ->join('gred', 'itemregistrations.GredID', '=', 'gred.GredID')
                ->where('itemregistrations.statusProID', '=', 1)
                ->select('itemregistrations.name','sections.sectionname', 'categories.categoryname', 'operasi.operasiname', 'itemregistrations.Nobadan', 'itemregistrations.lahir_yy', 'itemregistrations.pdrm_yy', 'gred.namagred', 'itemregistrations.itemRegistrationID', '');

        if($request->input('negeri_lahir') != ''){
            $query->where('itemregistrations.NegeriID', $request->input('negeri_lahir'));
        }

        if($request->input('kategori') != '') {
            $query->where('itemregistrations.CategoryID', $request->input('kategori'));
        }

        if($request->input('pangkat') != '') {
            $query->where('itemregistrations.OperasiID', $request->input('pangkat'));
        }

        if(request('umur')) {
            $query->whereRaw('YEAR(CURDATE()) - lahir_yy >= ?', [request('umur')]);  
        }

        if($request->input('gred') != '') {
            $query->where('itemregistrations.GredID', $request->input('gred'));
        }

        if(request('tempoh')) {
            $query->whereRaw('YEAR(CURDATE()) - pdrm_yy >= ?', [request('tempoh')]);  
        }

        if($request->input('negeri_perkhidmatan') != '') {
            $query->join('itemregistrationpangkat', 'itemregistrationpangkat.itemRegistrationID', '=', 'itemregistrations.itemRegistrationID')
                ->where('itemregistrationpangkat.NegeriID', $request->input('negeri_perkhidmatan'));           
        }

      if(request('tempoh_negeri')) {
            $query->select(DB::raw('m.itemRegistrationID, sum(m.duration)'))
                  ->from(DB::raw('(SELECT itemRegistrationID, NegeriID, yeartamatkhidmat - yearmulakhidmat as duration FROM itemregistrationpangkat) AS m 
                        RIGHT JOIN itemregistrations ON itemregistrations.itemRegistrationID=m.itemRegistrationID'))
                  ->distinct()
                  ->groupBy('m.itemRegistrationID');
      }

   $newitem = $query->get();

   return response::json($newitem);

The code involve to be solve is this(the last filter):

    if(request('tempoh_negeri')) {
            $query->select(DB::raw('m.itemRegistrationID, sum(m.duration)'))
                  ->from(DB::raw('(SELECT itemRegistrationID, NegeriID, yeartamatkhidmat - yearmulakhidmat as duration FROM itemregistrationpangkat) AS m 
                        RIGHT JOIN itemregistrations ON itemregistrations.itemRegistrationID=m.itemRegistrationID'))
                  ->distinct()
                  ->groupBy('m.itemRegistrationID');
      }

The problem is I need to get name column, sectionID column, CategoryID, OperasiID, NegeriID, GredID, from itemregistrations table from the $query statement. How to combine the last query filter in 'tempoh_negeri' with the previous one?
