当我设置我的分页以一次显示10条评论时,我的评论查询不会将评论回复计为显示计数的一部分,我该如何解决此问题以便我的评论回复计算在内?我的评论回复查询嵌套在我的主查询中以显示评论。
查询分页
SELECT COUNT(comment_id) FROM comments WHERE id = $id
显示评论的主要查询。
$dbc = mysqli_query($mysqli,"SELECT comments.*, users.*
FROM comments
LEFT JOIN users
ON comments.user_id = users.user_id
WHERE id = '" . $id . "'
AND parent_comment_id = 0
LIMIT $start, $display");
主要查询回复评论。
//display comments replies
$dbc2 = mysqli_query($mysqli, "SELECT comments.*, users.*
FROM comments
LEFT JOIN users
ON comments.user_id = users.user_id
WHERE id = '" . $id . "'
AND parent_comment_id >= 1");
//display comments replies
$dbc3 = mysqli_query($mysqli, "SELECT comments.*, users.*
FROM comments
LEFT JOIN users
ON comments.user_id = users.user_id
WHERE id = '" . $id . "'
AND parent_comment_id >= 1");
答案 0 :(得分:0)
也许这个查询,你能给出精确的数据库结构吗?
SELECT
com1.*,
users.*,
(
SELECT COUNT(*)
FROM comments AS com2
WHERE com2.parent_comment_id = com1.id
) AS num_replies
FROM comments AS com1
LEFT JOIN users ON com1.user_id = users.user_id
WHERE
com1.id = '" . $id . "'
AND com1.parent_comment_id = 0
LIMIT $start, $display
