如何将0值的所有列更新为特定值？

Question

我想将0值的所有列更新为1

控制器

$totalofitem=assets::where('item_name','like','keyboard')
->where('total_cost','like','0')->update(array('total_cost' => '1'));

知道了

$totalofitem=assets::where('item_name','like','keyboard')
->where('total_cost','like','0')->update(['total_cost' => 1]);
