Mysql – how to get query values, using Case/eloquent

I have this query and works fine:

SELECT id_categoria, categorias.descricao_categoria, 
    MAX(CASE WHEN month(data_compra) = 1 THEN valor ELSE NULL END) as Jan,
    MAX(CASE WHEN month(data_compra) = 2 THEN valor ELSE NULL END) as Fev,
    MAX(CASE WHEN month(data_compra) = 3 THEN valor ELSE NULL END) as Mar,
    FROM `movimentos` INNER JOIN categorias ON id_categoria = categorias.id GROUP BY id_categoria ORDER BY id_categoria;

The result is:

enter image description here

But, at laravel, I can’t get the result

$emps = DB::table('movimentos')
        ->join('categorias', 'categorias.id', '=', 'movimentos.id_categoria')
        ->select("id_categoria", "categorias.descricao_categoria", DB::raw (' "MAX(CASE WHEN month(data_compra) = 1 THEN valor ELSE null END) as jan", "MAX(CASE WHEN month(data_compra) = 2 THEN valor ELSE null END) as fev", "MAX(CASE WHEN month(data_compra) = 3 THEN valor ELSE null END) as mar" '))
        ->orderBY("id_categoria")
        ->groupBy("id_categoria")
        ->limit(1)->get();

How do I use/get months fields with foreach??

   foreach ($emps as $movimento) {
                $output .= '<tr>
                    <td>' . $movimento->descricao_categoria . '</td>
                    <td>' . $movimento->??? . '<td>
                </tr>';
            }

print_r($emps) show me:

IlluminateSupportCollection Object ( [items:protected] => Array ( [0] => stdClass Object ( [id_categoria] => 1 [descricao_categoria] => Veterinarios [MAX(CASE WHEN month(data_compra) = 1 THEN valor ELSE null END) as jan] => MAX(CASE WHEN month(data_compra) = 1 THEN valor ELSE null END) as jan [MAX(CASE WHEN month(data_compra) = 2 THEN valor ELSE null END) as fev] => MAX(CASE WHEN month(data_compra) = 2 THEN valor ELSE null END) as fev [MAX(CASE WHEN month(data_compra) = 3 THEN valor ELSE null END) as mar] => MAX(CASE WHEN month(data_compra) = 3 THEN valor ELSE null END) as mar

    Use selectRaw() instead of DB::raw() will fix this issue.

       $emps = DB::table('movimentos')
        ->join('categorias', 'categorias.id', '=', 'movimentos.id_categoria')
        ->select("id_categoria", "categorias.descricao_categoria")
        ->selectRaw("MAX(CASE WHEN month(data_compra) = 1 THEN valor ELSE null END) as jan")
        ->selectRaw("MAX(CASE WHEN month(data_compra) = 2 THEN valor ELSE null END) as fev")
        ->selectRaw("MAX(CASE WHEN month(data_compra) = 2 THEN valor ELSE null END) as fev")
        ->selectRaw("MAX(CASE WHEN month(data_compra) = 3 THEN valor ELSE null END) as mar")
        ->orderBY("id_categoria")
        ->groupBy("id_categoria")
        ->limit(1)
        ->get();

    You can try that and response is a Array(object).

    $datas = DB::select("SELECT id_categoria, categorias.descricao_categoria, 
           MAX(CASE WHEN month(data_compra) = 1 THEN valor ELSE NULL END) as Jan,
           MAX(CASE WHEN month(data_compra) = 2 THEN valor ELSE NULL END) as Fev,
           MAX(CASE WHEN month(data_compra) = 3 THEN valor ELSE NULL END) as Mar,
        FROM `movimentos` 
        INNER JOIN categorias ON id_categoria = categorias.id 
        GROUP BY id_categoria
        LIMIT = ?
        ORDER BY id_categoria", [1]);
