Laravel 4-數據表-調用數組中的成員函數getQuery（）

Question

以下查詢MySQL在MySQL MyAdmin中可以正常工作。

SELECT contacts.id, contacts.gsm, contacts.name, contacts.last_name, contacts.email, contacts.created_at,  if(temp.Count >= 1,temp.Count,0) as newCount
        FROM contacts
        LEFT JOIN
        (SELECT contacts.id, COUNT(groupcontact.id) AS Count
        FROM contacts
        LEFT JOIN groupcontact ON groupcontact.contacts_id = contacts.id
        LEFT JOIN groups ON groups.id = groupcontact.groups_id
        WHERE groups.id = :idGrupo
        GROUP BY contacts.id)
        temp ON temp.id = contacts.id

但是，當我嘗試在RAW DB中使用LARAVEL + Datatables運行時，返回此錯誤-{“ error”：{“ type”：“ Symfony \\ Component \\ Debug \\ Exception \\ FatalErrorException”，“ message”：“調用成員函數getQuery（）on array“，” file“：” C：\\ xampp \\ htdocs \\ mcdigital \\ laravel \\ vendor \\ bllim \\ datatables \\ src \\ Bllim \\ Datatables \\ Datatables.php“，” line“：256}}

我不知道為什么

LARAVEL控制器

$sql="SELECT contacts.id, contacts.gsm, contacts.name, contacts.last_name, contacts.email, contacts.created_at,  if(temp.Count >= 1,temp.Count,0) as newCount
            FROM contacts
            LEFT JOIN
            (SELECT contacts.id, COUNT(groupcontact.id) AS Count
            FROM contacts
            LEFT JOIN groupcontact ON groupcontact.contacts_id = contacts.id
            LEFT JOIN groups ON groups.id = groupcontact.groups_id
            WHERE groups.id = :idGrupo
            GROUP BY contacts.id)
            temp ON temp.id = contacts.id";
    $usuarios = DB::select( DB::raw($sql), array('idGrupo' => $idGrupo));

    return Datatables::of($usuarios)
    ->add_column('options', '
                    <label class="toggle yesNoGroup pull-left">
                      <input type="checkbox" name="checkbox-toggle" id="yesNoGroupchk-{{ $id }}" @if(newCount >0)checked@endif>
                      <i></i></label>
                    ')->make(); 

JS數據表

if ($(tablaName).length && !isNaN(idGroup)) {
        var $oTable = $(tablaName).dataTable({
            "bServerSide": true,
            "sAjaxSource": '/contact-list-group-load/'+idGroup,
            "autoWidth": true,
            "oLanguage": {
                "sProcessing":     '<image src="/images/ajax-loader.gif" alt="Cargando...">',
                "sLengthMenu":     "Mostrar _MENU_ contactos",
                "sSearch":         "Buscar:",
                "sZeroRecords":    "No se encontraron resultados",
                "sInfo":           "Mostrando _START_ al _END_ de un total de _TOTAL_ contactos",

                    "sNext":     "Siguiente",
                    "sPrevious": "Anterior"
                }
            },
            "aaSorting": [[0, 'desc']],
            "sDom":
                    "<'row'<'col-xs-6'l><'col-xs-6'f>r>"+
                    "t"+
                    "<'row'<'col-xs-12 text-center tableCuantosRegistros'i><'col-xs-12 text-center'p>>",
            "sLoadingRecords": '<image src="/images/ajax-loader.gif" alt="Cargando...">',
            "aoColumnDefs": [
                { "bSearchable": false, "aTargets": [ 5, 6 ] },
                { "bSortable": false, "aTargets": [ 5, 6 ] }
              ],
            "fnDrawCallback": function (oSettings) {

           },
            "iDisplayLength": 100
     });

也許只是問問如何將這個mysql查詢轉換為Laravel Eloquent或Laravel查詢生成器。 請指教。

提前致謝

您的錯誤說明了一切。

您應該將$ usuarios 數組轉換為Collection為：

$usuarios = DB::select( DB::raw($sql), array('idGrupo' => $idGrupo));
    $usuarios= collect($usuarios);
