    The following query should work for you. Select required columns from album_comments join it with comment_likes based on comment_id and check if the comment_likes user_id is equal to the user_id you sent from UI. ORDER BY DESC will return latest comments with LIMIT of 20.

    Select |ac.Column1, ac.Column2...ac.Column-n|, cl.like_bit
    FROM album_comments ac INNER JOIN comment_likes cl
    ON ac.id = cl.comment_id AND cl.user_id = |screen user_id|
    ORDER BY ac.id DESC LIMIT 20;
