Как оптимизировать эти запросы?

Question

Могу ли я избежать INNER JOIN в этих запросах?

"SELECT posts.status, posts.reports, posts.post_id, 
     posts.reply_counts, posts.sender, posts.content, 
     posts.image, posts.thumb, posts.date, 
     members.username, members.avatar, members.state 
FROM posts 
    INNER JOIN members ON posts.sender = members.member_id 
WHERE posts.parent_id=0 
    AND posts.wall_id=0 
    AND (
      (members.status=".MEMBER_STATUS_ACTIVE." AND 
      posts.reports<".MAX_REPORT_HIDE." 
      AND posts.status=".POST_STATUS_ACTIVE." 
     ) 
     OR 
     ".$bAdmin."=1 
     OR 
      (".$bMod."=1 AND 
      posts.status<>".POST_STATUS_DELETED." 
      ) 
     ) 
    AND posts.private_id=0 
ORDER BY posts.post_id DESC, posts.date DESC 
LIMIT ".(($pagenum-1) * PAGINATION).",".PAGINATION.";" 


"SELECT posts.status, posts.reports, posts.post_id, posts.reply_counts, 
     posts.sender, posts.content, posts.image, posts.thumb, posts.date, 
     members.username, members.avatar, members.state 
FROM posts 
    INNER JOIN members ON posts.sender = members.member_id 
    INNER JOIN notifies ON posts.post_id=notifies.post_id 
WHERE notifies.member_id=".$member_id." AND 
     posts.parent_id=0 AND 
     members.status=".MEMBER_STATUS_ACTIVE." AND 
     posts.reports<".MAX_REPORT_HIDE." AND 
     posts.status=".POST_STATUS_ACTIVE." AND 
     posts.private_id=0 
ORDER BY posts.last_update DESC, posts.date DESC 
LIMIT ".(($pagenum-1) * PAGINATION).",".PAGINATION.";"

Если вам нужны все строки из таблицы как раз соответствует существуют, то вы должны использовать внутреннее соединение.
