更新到 laravel 10 后，我无法像这样执行原始查询：

$statement = 'SELECT';
    foreach ($tables = collect(availableTables()) as $name => $table_name) {
        if ($tables->last() == $table_name) {
            $statement .= "( SELECT COUNT(*) FROM $table_name) as {$table_name}";
        }
        else {
            $statement .= "( SELECT COUNT(*) FROM $table_name) as {$table_name}, ";
        }
    }
    $query  = DB::select(DB::raw($statement));

这返回给我以下错误：

PDO::prepare (): Argument #1 ($query) must be of type string, Illuminate\Database|Query\ Expression given

我应该怎么做才能解决这个问题
