问题描述
当我尝试运行以下查询时，它不返回任何内容:
When I try to run the following query, it returns nothing:
Item::where(\DB::raw('date_field < NOW()'))->get()
这样做的原因是，将is null附加到生成的MySQL查询中，如下所示:
The reason for this is, that is null is appended to the generated MySQL query like this:
SELECT * FROM items WHERE date_field < NOW() is null;
为什么is null部分被附加到上面的查询中?
Why does the is null part get appended to the above query?
推荐答案
This is a known issue in Laravel and has been reported on their GitHub page. Use whereRaw() instead and pass a string:
Item::whereRaw('date_field < NOW()')->get()
