yajra/laravel-datatables search is not working with laravel 5.7

Question

Here is join code and assign Datatables

Route::get('Productos',function(){
  $query = DB::table('producto as e')
         ->select('e.cod_producto', 'e.nom_producto', 'e.precio_venta', 'd.nombre as nombre_marca', 'j.nombre as nombre_tipo', DB::raw('if(e.estado = 0,\'Activo\',\'Eliminado\') as estado'))
         ->join('marca as d','e.cod_marca', '=', 'd.cod_marca')
         ->join('tipo-producto as j', 'e.cod_tipo_producto', '=', 'j.cod_tipo_producto');

    return datatables()
              ->of($query)
              ->addColumn('btn','actions')
              ->rawColumns(['btn'])
              ->toJson();

});

Here is jQuery code

$(document).ready(function(){
    $('#Productos').DataTable({
      "bAutoWidth": false,
       "destroy": true,
       "responsive": true,
       "serverSide":true,
       "ajax":'{{url('api/Productos')}}',
       "columnDefs": [ {
         "targets": 'no-sort',
         "orderable": false,
         "searchable": false,
       }],
       "columns":[
         {data: 'cod_producto'},
         {data: 'nom_producto'},
         {data: 'precio_venta'},
         {data: 'nombre_marca'},
         {data: 'nombre_tipo'},
         {data: 'estado'},
         {data: 'btn'},
       ]
    });
});

Now when i try to search something it is giving me alert with error Here is an error message

Exception Message:↵↵SQLSTATE[42000]: Syntax error or access violation: 1583 Incorrect parameters in the call to native function 'LOWER' (SQL: select count(*) as aggregate from (select '1' as row_count from producto as e inner join marca as d on e.cod_marca = d.cod_marca inner join tipo-producto as j on e.cod_tipo_producto = j.cod_tipo_producto where (LOWER(producto as e.cod_producto) LIKE %1% or LOWER(producto as e.nom_producto) LIKE %1% or LOWER(producto as e.precio_venta) LIKE %1% or LOWER(marca.nombre) LIKE %1% or LOWER(tipo-producto.nombre) LIKE %1% or LOWER(producto as e.estado) LIKE %1%)) count_row_table)

Answer 1

hai i have a same problem, this my datatable :
public function yajra(Request $request)
    {
        DB::statement(DB::raw('set @rownum=0'));
        $pengeluaran = DB::table('pengeluaran as a')->join('jenis_pengeluaran as b','a.jenis_pengeluaran', '=','b.id')->select([
            DB::raw('@rownum  := @rownum  + 1 AS rownum'),
            'a.id',
            'a.tanggal',
            'a.no_nota',
            'a.uraian',
            'a.jumlah',
            'a.jenis_pengeluaran',
            'b.nama']);
        $datatables = Datatables::of($pengeluaran)->addColumn('action', function ($pl) {
                $url_edit = url('pengeluaran/'.$pl->id);
                $url_hapus = url('pengeluaran/'.$pl->id);
                return '<a href="'.$url_edit.'" class="btn btn-outline-secondary"> <i class="ni ni-ruler-pencil"></i>Edit</a> <a href="'.$url_hapus.'" class="btn btn-outline-secondary btn-hapus" style="color:red;"> <i class="ni ni-fat-remove" style="color:red;"></i>Hapus</a>';
            })->editColumn('jumlah', function($pl){
                $jumlah = $pl->jumlah;
                $jumlah = number_format($jumlah,0);
                $jumlah = str_replace(',', '.', $jumlah);
                return $jumlah;
            })->editColumn('tanggal', function($pl){
                $tanggal = $pl->tanggal;
                $tanggal = date('d M Y', strtotime($tanggal));
                return $tanggal;
            });

        if ($keyword = $request->get('search')['value']) {
            $datatables->filterColumn('rownum', 'whereRaw', '@rownum  + 1 like ?', ["%{$keyword}%"]);
        }

        return $datatables->make(true);
    }

and this is my javascript
<script type="text/javascript">
  $(document).ready(function(){
    $('#peng').DataTable({
        processing: true,
        serverSide: true,
        ajax: "{{ url('pengeluaran/yajra')}}",
        columns: [
            // or just disable search since it's not really searchable. just add searchable:false
            {data: 'rownum', name: 'rownum'},
            {data: 'tanggal', name: 'tanggal'},
            {data: 'no_nota', name: 'no_nota'},
            {data: 'uraian', name: 'uraian'},
            {data: 'jumlah', name: 'jumlah'},
            {data: 'nama', name: 'nama'},
            {data: 'action', name: 'action', orderable: false, searchable: false}
        ]
    });
i'm using "yajra/laravel-datatables-oracle": "~9.0" and laravel 7

Set your Datatable columns name base on your join data field from your query

Here is the sample

 "columns":[
     {data: 'cod_producto', name:'e.code_product'},
     {data: 'nom_producto', name:'e.nom_producto'},
    ....
