Laravelで直接SQL文を実行する

Posted at

Laravelで直接SQLを実行するにはその種類によってメソッドが変わります。参照系の場合には DB::select() を利用します。

$sql = "select i.* from input_tmps i
where i.id is not null;";
$rows = DB::select($sql);

$retArray = [];
/** 結果取得 **/
foreach($rows as $row) {
  $retArray[$row->id][] = $row->value;
}

LOCK文等の場合には DB::unprepared() を使います。

DB::unprepared( 'LOCK TABLES ' .
  DB::getTablePrefix() . 'input_tmps1 WRITE,' .
  DB::getTablePrefix() . 'input_tmps2 WRITE,' .
  DB::getTablePrefix() . 'input_tmps3 WRITE, ' .
  DB::getTablePrefix() . 'input_tmps4 WRITE'
);
