Comment combiner et optimiser ces deux requêtes?

Question

Voici ma requête principale qui tire dans les informations de fil comme une ligne, il manque le nombre de votes et actuellement je tire cela avec une deuxième requête.

SELECT Group_concat(t.tag_name) AS `tags`, 
     `p`.`thread_id`, 
     `p`.`thread_name`, 
     `p`.`thread_description`, 
     `p`.`thread_owner_id`, 
     `p`.`thread_view_count`, 
     `p`.`thread_reply_count`, 
     `p`.`thread_comment_count`, 
     `p`.`thread_favorite_count`, 
     `p`.`thread_creation_date`, 
     `p`.`thread_type_id`, 
     `p`.`thread_edited_date`, 
     `u`.*, 
     `x`.*, 
     `t`.* 

FROM  `shoop_posts` AS `p` 
     INNER JOIN `shoop_users` AS `u` 
      ON u.user_id = p.thread_owner_id 
     LEFT JOIN `shoop_tags_map` AS `x` 
      ON x.thread_id = p.thread_id 
     LEFT JOIN `shoop_tags` AS `t` 
      ON t.tag_id = x.tag_id 


WHERE (p.thread_id = '1') 
GROUP BY `p`.`thread_id` 

Ma deuxième requête qui tire dans le nombre de votes par fil:

SELECT Sum(vote_value) 
FROM shoop_votes 
     INNER JOIN shoop_vote_codes 
     ON shoop_votes.vote_type = shoop_vote_codes.vote_type 
WHERE thread_id = 1 
     AND shoop_votes.vote_type = 3 
     OR shoop_votes.vote_type = 2 

Un type de vote de 2 est un upvote, 3 est un downvote. Voici le schéma si vous en avez besoin, et certaines données de l'échantillon:

CREATE TABLE `shoop_posts` (

    `thread_id` int(11) unsigned NOT NULL auto_increment, 

    `thread_name` text,

Answer 1

Si je vous comprends bien, tout en utilisant un sous-requête fera ce que vous êtes après:

SELECT Group_concat(t.tag_name) AS `tags`, 
     `p`.`thread_id`, 
     `p`.`thread_name`, 
     `p`.`thread_description`, 
     `p`.`thread_owner_id`, 
     `p`.`thread_view_count`, 
     `p`.`thread_reply_count`, 
     `p`.`thread_comment_count`, 
     `p`.`thread_favorite_count`, 
     `p`.`thread_creation_date`, 
     `p`.`thread_type_id`, 
     `p`.`thread_edited_date`, 
     `u`.*, 
     `x`.*, 
     `t`.*, 
     `v`.VoteTotal 

FROM  `shoop_posts` AS `p` 
     INNER JOIN `shoop_users` AS `u` 
      ON u.user_id = p.thread_owner_id 
     LEFT JOIN `shoop_tags_map` AS `x` 
      ON x.thread_id = p.thread_id 
     LEFT JOIN `shoop_tags` AS `t` 
      ON t.tag_id = x.tag_id 
     LEFT JOIN (SELECT thread_id, Sum(vote_value) as VoteTotal 
        FROM shoop_votes 
         INNER JOIN shoop_vote_codes 
         ON shoop_votes.vote_type = shoop_vote_codes.vote_type 
        WHERE shoop_votes.vote_type = 3 
          OR shoop_votes.vote_type = 2 
        GROUP BY thread_id) as `v` 
      ON p.thread_id = v.thread_id 
WHERE (p.thread_id = '1') 
GROUP BY `p`.`thread_id` 

Cela vous permettra tous les threads aussi bien si vous venez de laisser où dernier où p.thread_id clause.
