使用 Raw,如何返回更新行的集合?
Using Raw, how to return collection of updated row?
例如:
$updated = DB::table('users')->where('id', 1)->update(['votes' => 123]);
我期待 dd($updated)
返回更新后的集合行,但它返回了 1.
I was expecting dd($updated)
to return updated row of collection but it returned 1.
{{$updated->votes}} should return 123
它不是这样工作的.你不能指望这个查询会返回一个对象:
That's not how it works. You can't expect this query will return you an object:
$updated = DB::table('users')->where('id', 1)->update(['votes' => 123]);
如果您只想按照问题中提到的方式使用查询生成器,则需要手动获取一个对象:
If you want to use Query Builder only as you mentioned in your question, you'll need to get an object manually:
$data = DB::table('users')->where('id', 1)->first();
使用 Eloquent,您可以使用 updateOrCreate()
:
With Eloquent you can use the updateOrCreate()
:
$data = User::where('id', 1)->updateOrCreate(['votes' => 123]);
这将返回一个对象.update()
将返回布尔值,因此您不能在这里使用它.
This will return an object. update()
will return boolean, so you can't use it here.
