Wordpress - Uzyskaj liczbę postów ORAZ komentarzy dziennie

Myślę, że to nie jest najlepsze zapytanie, jakie możesz napisać, ale wydaje się, że działa

CREATE VIEW commentsCount (date, counter) AS
SELECT
    DISTINCT DATE(comment_date) AS date,
    IFNULL(COUNT(comment_ID),0) AS total
FROM wp_comments
GROUP BY date ORDER BY total DESC

CREATE VIEW postsCount (date, counter) AS
SELECT
    DISTINCT DATE(post_date) AS date,
    IFNULL(COUNT(ID),0) AS total
FROM wp_posts
GROUP BY date ORDER BY total DESC

SELECT
    postsCount.date,
    IFNULL(postsCount.counter,0),
    IFNULL(commentsCount.counter,0),
    (IFNULL(postsCount.counter,0)*10 + IFNULL(commentsCount.counter, 0))
FROM commentsCount RIGHT JOIN postsCount 
    ON DATE(postsCount.date) = DATE(commentsCount.date)
GROUP BY postsCount.date
union
SELECT
    commentsCount.date,
    IFNULL(postsCount.counter,0),
    IFNULL(commentsCount.counter,0),
    (IFNULL(postsCount.counter,0)*10 + IFNULL(commentsCount.counter, 0))
FROM commentsCount LEFT JOIN postsCount 
    ON DATE(postsCount.date) = DATE(commentsCount.date)
GROUP BY commentsCount.date
