How to select from subquery using Laravel Query Builder?

I'd like to get value by the following SQL using Eloquent ORM. - SQL SELECT COUNT(*) FROM (SELECT * FROM abc GROUP BY col1) AS a; Then I considered the following. - Code $sql = Abc::from('abc AS a')->groupBy('col1')->toSql(); $num = Abc::from(\DB::raw($sql))->count(); print $num; I'm looking for a better solution. Please tell me simplest solution.
