Laravel 5执行自己的查询

Question

是否有可能在Laravel 5中执行此查询？

select t1.*, v.hash from 
    (select dr.*, d.id as d_id, d.name, d.user_id from directory d 
    left join directory_relations dr on d.id = dr.directory_id 
    union select dr.*, d.id as d_id, d.name, d.user_id from directory_relations dr 
    left join directory d on d.id = dr.directory_id) t1 
left join videos v on t1.video_id = v.id WHERE t1.user_id = 265 

Answer 1

您可以使用DB ::原料

$results = DB::select(DB::raw("select t1.*, v.hash from 
    (select dr.*, d.id as d_id, d.name, d.user_id from directory d 
    left join directory_relations dr on d.id = dr.directory_id 
    union select dr.*, d.id as d_id, d.name, d.user_id from directory_relations dr 
    left join directory d on d.id = dr.directory_id) t1 
left join videos v on t1.video_id = v.id WHERE t1.user_id = :user_id"), array(
    'user_id' => 265, 
)); 

Answer 2

通过查询生成器，你可以不喜欢它：

$union = DB::select(['dr.*', 'd.id as d_id', 'd.name', 'd.user_id']) 
    ->from('directory_relations as dr') 
    ->leftJoin('directory as d', 'd.id', '=', 'dr.directory_id'); 

$base = DB::select(['dr.*', 'd.id as d_id', 'd.name', 'd.user_id']) 
    ->from('directory as d') 
    ->leftJoin('directory_relations as dr', 'd.id', '=', 'dr.directory_id') 
    ->union($union); 

DB::select('t1.*', 'v.hash') 
    ->from(DB::raw("({$base->toSql()}) as t1")) 
    ->mergeBindings($base->getQuery()) 
    ->leftJoin('videos as v', 't1.video_id', '=', 'v.id') 
    ->where('t1.user_id', 265) 
    ->get();
