mysql不同的select查詢在一個

Question

我怎麼可以有一個查詢以下內容： 我想從我的評論表所有人如何評論一個給定的post_id並比檢查多少時間用戶評論，基於他的名字。我想，以避免有2個不同的查詢它

我已經被post_ID嘗試以下，但不會返回預期的結果

SELECT comments.*, COUNT(approved.comment_approved) AS has_commented FROM wp_comments AS comments 
    INNER JOIN wp_comments AS approved 
    ON comments.comment_author = approved.comment_author 

WHERE comments.comment_post_ID =14616 
GROUP BY comments.comment_content 

Answer 1

你不應該羣？ （這將返回只有一行）

SELECT 
    comments.* 
, COUNT(approved.comment_approved) AS "has_commented" 
FROM wp_comments AS comments 
JOIN wp_comments AS approved 
    ON (comments.comment_author = approved.comment_author) 
WHERE comments.comment_post_ID = 14616 
GROUP BY comments.comment_post_ID 
; 

還是希望每「批」一行對此有何評論？
