mysqlクエリは、PHPを使用して2回重複行を取得します

Question

SELECT bp.postID, bp.postTitle, bp.postSlug, bp.authorName,bp.coverPic, bp.postDesc, bp.postDate FROM blog_posts bp INNER JOIN blog_post_cats bpc ON bp.postID=bpc.postID INNER JOIN blog_cats bc ON bpc.catID=bc.catID WHERE bp.STATUS=1 AND catSlug="World-In-360" ORDER BY postID DESC 

このクエリは各行を2回フェッチしています。これに関する助け？

Answer 1

SELECT bp.postID, bp.postTitle, bp.postSlug, bp.authorName,bp.coverPic, bp.postDesc, bp.postDate 
    FROM blog_posts bp 
INNER JOIN blog_post_cats bpc 
    ON bp.postID=bpc.postID 
INNER JOIN blog_cats bc 
    ON bpc.catID=bc.catID 
WHERE bp.STATUS=1 AND catSlug="World-In-360" 
GROUP BY postID 
ORDER BY postID DESC
