我在网站上尝试了各种解决方案,但不幸的是我没有成功。我需要这个已经采用字段“ vote_up”的最大值的结果的查询,也可以采用第二个附加值。它在给定日期(posted_date),开始日期和结束日期之内提取结果。

SELECT * 
FROM   stories S 
       LEFT JOIN categories C 
              ON C.category_id = S.c_id 
       LEFT JOIN (SELECT voted_story, 
                         voter_ip 
                  FROM   votes 
                  WHERE  voter_ip = '$ip_address' 
                  GROUP  BY voted_story) V 
              ON V.voted_story = S.story_id 
WHERE  S.story_active = 1 
ORDER  BY S.vote_up DESC 
LIMIT  0, 16 

为澄清起见,我遇到的困难是使我出错的语法,尤其是我不知道如何在同一查询中插入两个“ where”。

您可以添加其他WHERE条件条款,以便同时检查过帐日期。

SELECT * 
FROM   stories S 
   LEFT JOIN categories C 
          ON C.category_id = S.c_id 
   LEFT JOIN (SELECT voted_story, voter_ip 
              FROM   votes 
              WHERE  voter_ip = "$ip_address" 
              GROUP  BY voted_story) V 
          ON V.voted_story = S.story_id 
WHERE
    S.story_active = 1 AND
    S.posted_date > "$startDate" AND
    S.posted_date < "$endDate"
ORDER  BY S.vote_up DESC 
LIMIT  0, 16
