Laravel，我如何简单地执行复杂的查询

Question

我需要统计一个月内发送的电子邮件，最后发送给每个人。我想象这样的事情：

$mes=8; // or any month
$search= [100,101,102,103]; // dni
$sql = "
SELECT A.dni, $mes AS mes, COUNT(*) AS total, B.lastet_date 
FROM emails AS A
LEFT JOIN (
          SELECT dni, MAX(date_sended) AS lastet_date
          FROM emails 
          GROUP BY dni
          ) AS B
          ON B.dni = A.dni 
WHERE MONTH(date_sended) = $mes 
AND A.dni IN ('".implode("', '",$search)."') 
GROUP BY A.dni";

我怎样才能简单地使用原始方法或类似方法执行它？

Answer 1

您可以使用 DB::select 助手：

use Illuminate\Support\Facades\DB;
...
$results = DB::select($sql)

这将return一个集合，其中每个元素都是查询结果的一行。
