Create a Insert… Select statement in Laravel

Question

I\'m needing to convert this query for Laravel and I\'m having issues trying to create an Insert... Select statement using Laravel\'s Eloquont ORM, or Queries. I\'m not sure

Answer 1

In Laravel 5.5, I created a helper function for executing easier:

class QueryHelper
{

    /**
     * @param string $model
     * @param array $columns
     * @param Builder $select
     * @return bool
     */
    public static function insertFromSelectStatement($model, $columns, $select)
    {
        /** @var \Illuminate\Database\Query\Builder $query */
        $query = (new $model)->getQuery();
        $sql = "insert into {$query->from} (". implode(', ', $columns) .") {$select->toSql()}";
        return $query->getConnection()->insert($sql, $select->getBindings());
    }
}

For example:

$notification = Notification::create([
    'title' => 'this is title',
    'message' => 'this is message',
]);
$now = DB::raw("'". Carbon::now()->toDateTimeString() ."'");
$selectActivatedUsers = User::select('id', $notification->id, $now, $now)->where('status', '=', 'activated');
// insert notifications to activated users
QueryHelper::insertFromSelectStatement(UserNotification::class, ['user_id', 'notification_id', 'created_at', 'updated_at'], $selectActivatedUser);
