如何在laravel

Question

如何在laravel查询构建器中执行此操作？ （这基本上可以获得你在投票系统中的当前位置）

SELECT position FROM 
    (SELECT participant.target_user_id, @rownum := @rownum + 1 as position FROM 
        (SELECT target_user_id, count(*) as votes FROM contest_participants_votes GROUP BY 
        target_user_id ORDER BY votes DESC) as participant 
    JOIN (SELECT @rownum := 0) r) x
WHERE target_user_id = 1

Answer 1

我们在占位符

中使用了这样的原始语句

$position = \DB::select(\DB::raw(
            'SELECT position FROM 
                (SELECT participant.target_user_id, @rownum := @rownum + 1 as position FROM 
                  (SELECT target_user_id, count(*) as votes FROM contest_participants_votes GROUP BY 
                  target_user_id ORDER BY votes DESC) as participant 
                JOIN (SELECT @rownum := 0) r) x
            WHERE target_user_id = ?'), [$pid]);
