将查询转换为雄辩的orm laravel

Question

我想转换此查询

select sum(TIME_TO_SEC(`duration`)) from `table`

对Laravel 5的Eloquent ORM

Answer 1

我不确定在什么情况下，但如果我找到你，你想要

select sum(TIME_TO_SEC(`duration`)) from `table`

是

DB::table('table')
->select(DB::raw('sum(TIME_TO_SEC(`duration`))')
->get();

Answer 2

它适用于我：

Table::selectRaw('sum( TIME_TO_SEC(`duration`) ) as duration')->first();
