php - 如何使用 laravel Raw 查询选择行

Question

我想从我的事件表中选择给定日期的所有行。为此，我使用了 whereRaw() 子句。这是我执行此操作的代码:

$activities = Activity::whereRaw('Date(created_at) as date',$date)->get();
dd($activities);

但是我得到一个错误:

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'as date' at line 1 (SQL: select * from activities where Date(created_at) as date)

请帮我解决这个问题。这是 $date 的 dd():

"2019-12-12"

Answer 1

然后去:

$activities = Activity::whereDate('created_at', $date)
            ->get();

请记住，$date 必须采用日期格式。 检查https://laravel.com/docs/5.8/queries#where-clauses供引用。
