如何在laravel 4.2中查询＆＃39; as和表达式＆＃39;

Question

尝试将此SQL查询转换为Laravel查询

$query = "SELECT *, ( 3959 * acos( cos( radians('$lat') ) * 
cos( radians( latitude ) ) * 
cos( radians( longitude ) - 
radians('$lon') ) + 
sin( radians('$lat') ) * 
sin( radians( latitude ) ) ) ) 
AS distance FROM yourtable HAVING distance < '$miles' ORDER BY distance ASC LIMIT 0, 5";

继承人我做了什么，但我想我真的不知道这件事。

$stores = DB::table('stores')
->select( DB::raw( 'stores.*, ( ( 3959 * acos( cos( radians('.$lat.') ) * 
cos( radians( stores.latitude ) ) * 
cos( radians( stores.longitude ) - 
radians('.$lon.') ) + 
sin( radians('.$lat.') ) * 
sin( radians( stores.latitude ) ) ) ) 
as distance' ) )
    ->orderBy('distance')->where('domain',$domain->appEnv)->get();
