[英]Laravel query subquery
例如,我有2個查詢:
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,如何在laravel的查詢生成器中將它們合並為一個查詢? 對於在where語句中使用selects語句,我找不到很多東西。
你可以聯合在一起,像
// 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();
您也可以使用orWhere函數
$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();
