将MySQL选择循环查询更改为Laravel 5.5

Question

如何将此查询更改为Laravel 5.5

"SELECT ROUND((COUNT(STATUS)/(SELECT COUNT(*) FROM data_ap))*100,1)
 FROM data_ap WHERE STATUS LIKE '%UP%'";

Answer 1

类似的东西：

\DB::table('data_ap')
  ->select(\DB::raw('ROUND((COUNT(STATUS)/(SELECT COUNT(*) FROM data_ap))*100,1) as calc'))
  ->where('STATUS','like','%UP%')
  ->get();

Answer 2

我认为您必须使用Raw Expressions保留原生查询，以获取更多https://laravel.com/docs/5.6/queries#raw-expressions

Answer 3

@Muhammad Anwari：您只需指向目标列/别名即可

\DB::table('data_ap')
   ->select(\DB::raw('ROUND((COUNT(STATUS)/(SELECT COUNT(*) FROM data_ap))*100,1) as calc'))
   ->where('STATUS','like','%UP%')
   ->first()->calc;
