Question

例如，我有2个查询：

1

$q = SomeContent::select('somecontent_id')
    ->where('slug', Request::segment(2))
    ->where('something', $something)
    ->first();

2

$req = SomeContent::select('slug')
    ->where('something', $anothersomething)
    ->where('somecontent_id', $q->somecontent_id)
    ->first();

如果可能的话，如何在laravel的查询构建器中将这些作为一个查询合并在一起？我找不到很多关于在where语句中使用choose语句的信息。

Answer 1

你可以union将它们放在一起，比如

// The query builder also provides a quick way to "union" two queries together:

$q = SomeContent::select('somecontent_id')
    ->where('slug', Request::segment(2))
    ->where('something', $something);

$req = SomeContent::select('slug')
    ->where('something', $anothersomething)
    ->where('somecontent_id', $q->somecontent_id)
    ->union($q)->get();

Answer 2

你也可以使用orWhere函数

$q = SomeContent::select('somecontent_id')
      ->where('slug', Request::segment(2))
       ->where('something', $something)
        ->orWhere(function($query)
        {
            $query->where('something', $anothersomething)
          ->where('somecontent_id', $q->somecontent_id)
           ->union($q)->get();
        })
        ->get();
