Question

나는 해당 투표에 대한 의견 및 요약 통계를 선택하려고합니다. 모든 의견에 투표가있는 것은 아니며 투표지가 1 표 이상을 가질 수 있습니다. 여기 내 쿼리는 다음과 같습니다.

select 
    `article-comments`.id, 
    `article-comments`.user as user_id, 
    concat(users.first_name, ' ', users.last_name) as name, 
    users.job_title, 
    users.company_name, 
    avatar, 
    `article-comments`.content, 
    datediff(now(), `article-comments`.date_added) as diff, 
    `article-comments`.date_added as date, 
    count(`comment-votes`.id) as votes_count, 
    sum(`comment-votes`.score) as votes_score 
from 
    `article-comments` left outer join `comment-votes` on `article-comments`.id = `comment-votes`.comment, 
    users 
where 
    `article-comments`.status = 1 
&& `article-comments`.article = $resource_id 
&& `article-comments`.user = users.id 
&& `comment-votes`.status = 1 
order by 
    `article-comments`.id asc 

이것은 조인없이 완벽하게 작동하지만 그걸로 1 행만 반환합니다.

아이디어가 있으십니까?
