有什么办法可以让这个查询使用 laravel 工作吗?DB::raw 或 Eloquent 用法无关紧要.
Any way to make this query work using laravel? DB::raw or Eloquent usage doesn't matter.
SELECT count(DISTINCT name) FROM tablename;
这是我尝试过但无法获得正确输出的方法:
Here's what i've tried but cannot get the proper output:
EloquentTableName::select(DB::raw('count(DISTINCT name) as name_count'))->get();
这会返回类似的内容,我想解决这个问题:
This returns something like this and i'd like to fix that:
([{"name_count":"15"}])
我只想数到 15.
你可以这样简单地用 count 替换 get:
you can simply replace get with count in this way:
$count = DB::table('tablename')->count(DB::raw('DISTINCT name'));
还可以:
DB::table('tablename')->distinct('name')->count('name');
这篇关于Laravel 不同计数的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持html5模板网!
