我遇到了此查询如何返回数据的问题。 timestamp
返回正确,newpost
返回正确,但已解决的帖子和已关闭的帖子无法恢复正确。我遇到的问题是,我今天有一个实例,今天有人关闭了一堆票,但是因为它们比过去7天发现的更早(这是为了制图),所以不算数他们因为我使用按组创建的顺序。创建的东西是创建它的日期,用作图表的timestamp
以及故障单的创建时间以及newpost
。
在一天结束时,第18天应该有12 newposts
,1 solved
和22 closed
,但它不起作用
SELECT
DATE(created) timestamp,
COUNT(created) newpost,
COUNT(CASE WHEN DATE(closed) AND (sent = 0 OR sent = 1) THEN closed END) solvedpost,
COUNT(CASE WHEN DATE(closed) AND (sent = 2) THEN closed END) closedpost
FROM
tickets
GROUP BY DATE(created)
ORDER BY DATE(created) DESC
LIMIT 7

好的,我认为我明白你想要什么,我会澄清。希望我的写作能帮助你解释未来的帖子。
对于您的数据,您拥有创建时,关闭时以及关闭状态的故障单。
我需要根据相关活动的每个日期检索摘要。因此,即使机票可能已于10月9日创建并于10月18日关闭,我也需要将截止日期活动显示在第18条摘要记录中。
要执行此操作,您需要一个子查询来汇总所有已关闭的活动,并根据相关日期对主要活动进行汇总。但是现在,如果你有一个没有创建门票的日期怎么办,但有些已关闭...我知道,异常情况,我不打算查询。
所以,调整后的查询为
SELECT
DATE(T1.created) DateActivity,
COUNT(T1.*) newpost,
MAX( COALESCE( ClosedActivity.ClosedEntries, 0 )) as ClosedEntries,
MAX( COALESCE( ClosedActivity.ClosedPost, 0 )) as ClosedPosts,
MAX( COALESCE( ClosedActivity.SolvedPost, 0 )) as SolvedPosts
FROM
tickets T1
LEFT JOIN
( select
DATE( closed ) DateClosed,
COUNT(*) as ClosedEntries,
SUM( case when sent = 2 then 1 else 0 end ) as ClosedPost,
SUM( case when sent = 0 OR sent = 1 then 1 else 0 end ) as SolvedPost
from
tickets
where
closed >= date_add( current_date(), interval -7 day )
GROUP BY
DATE(closed) ) ClosedActivity
ON
DATE( T1.Created ) = ClosedActivity.DateClosed
where
T1.created >= date_add( current_date(), interval -7 day )
GROUP BY
DATE(T1.created)
ORDER BY
DATE(T1.created) DESC
LIMIT 7
注意我应用日期数学从当前减去7天。这样,它只会抓取过去7天内创建故障单的活动。如果您的数据有多年的数据,那么它将全部剔除,然后只返回最近的数据。我只从最近7天的活动开始。
由于已关闭的票证永远不会早于创建票证,因此该票证在7天内是合格的。
现在,对于内部查询的每个日期的单独行,我正在应用该结果的MAX(),因为它将永远不会根据创建的票证的外部条目数进行更改。否则,引擎可能会唠叨不属于不是聚合列的group by子句的列。
我认为这就是你要找的东西。

DATE(已关闭)返回DATE而不是布尔值,您应该考虑以下内容:
closed>=curdate()
覆盖今天的日期并避免通过函数运行字段值
答案 2 :(得分:0)
更改
COUNT(CASE WHEN DATE(closed) AND (sent = 2) THEN closed END) closedpost
到
SUM(DATE(closed) = DATE(created) AND (sent = 2)) closedpost
(另一个柜台也是如此。)
