I needed to turn this SQL Query in to Eloquent and I'm wondering if what I did is safe and correct way of doing it.

SQL Query:

SELECT t2.`group`
     , t2.`item`
     , GROUP_CONCAT(IF(t1.locale = 'en', t2.`text`, NULL)) AS en
     , GROUP_CONCAT(IF(t1.locale = 'et', t2.`text`, NULL)) AS et
FROM `language_entries` t2 
LEFT JOIN `languages` t1 ON t1.`id` = t2.`language_id`
GROUP BY t2.`group`,
         t2.`item`

Eloquent:

$langA = DB::connection()->getPdo()->quote("en");
$langB = DB::connection()->getPdo()->quote("et");

$sql = DB::table(DB::raw('language_entries t2'))
          ->select(
            't2.group',
            't2.item',
            DB::raw('GROUP_CONCAT(IF(t1.locale = "'. $langA .'", t2.`text`, NULL)) AS '. $langA),
            DB::raw('GROUP_CONCAT(IF(t1.locale = "'. $langB .'", t2.`text`, NULL)) AS '. $langB)
          )
          ->leftJoin(DB::raw('languages t1'), function($join)
          {
            $join->on('t1.id', '=', 't2.language_id');
          })
          ->groupBy('t2.group', 't2.item')
          ->get();
var_dump($sql);

I will most likely replace DB::table() with using a protected $table inside my Model.
