Mysql 计算两次之间的小时数

几天前我问了一个类似的问题，但对于我所寻找的东西，特别是SQL（问题是）

基本上，我有以下问题：

    SELECT DAYNAME(arrivalTime) AS day, COUNT(*) AS count
    FROM bookings
    WHERE HOUR(arrivalTime) = 13
    AND DAYNAME(arrivalTime) = 'Monday'

这将计算星期一13:00开始的预订的条目数。如何更改此设置，以便计算从到达时间到取车时间的每一小时

例如，如果我的到达时间-拾取时间为13:00-17:00那么13:00、14:00、15:00和16:00都会将其计算为一个条目

他提出了一些建议，但没有真正做到

编辑：

我正在制作的日历：

我的数据库：

样本和预期输出：

arrivalTime - pickupTime 

13 - 15 (hours 13, 14 are counted)

10 - 14 (hours 10, 11, 12, 13 are counted)

16 - 17 (hours 16 are counted)

13 - 17 (hours 13, 14, 15, 16 are counted)

11 - 12 (hours 11 are counted)

基本上，现在它只是简单地计算到达时间为X的条目数。因此，如果我们有10个条目在星期一的13:00开始，在我链接的HTML表上，它将在13:00旁边有数字10。我想让它每小时都在计算到底有多少次预订

为了使它更容易想象，这是简单地把一个狗窝。我们正在检查每小时养多少只狗。因此，如果预订时间为13:00-15:00，则不应仅将+1添加到13:00，还应添加到14:00，因为时间重叠。也许比我想象的要复杂一点

编辑2：

现在我的函数中有了这个查询

SELECT DAYNAME(arrivalTime) AS day, COUNT(*) AS count
FROM bookings
WHERE HOUR(arrivalTime) = $hour
AND DAYNAME(arrivalTime) = '$dayname'

在HTML中，我像这样传递值

<td>
    <span>
        <p style="float:left">10:00</p>
        <p style="float:right">&nbsp;&nbsp;&nbsp;(<?php $var->get_CalendarCount($conn,10,'Monday'); ?>)</p>
    </span>
</td>

10:00
（）

你是说像这样

SELECT DAYNAME(arrivalTime) AS day, COUNT(arrivalTime) AS count
  FROM bookings
  WHERE TIME(arrivalTime) BETWEEN '13:00:00' AND '17:00:00'
  AND DAYNAME(arrivalTime) = 'Monday'

或者，如果您只需要13、14、15、16、17，那么：

SELECT DAYNAME(arrivalTime) AS day, COUNT(arrivalTime) AS count
  FROM bookings
  WHERE (TIME(arrivalTime) BETWEEN '13:00:00' AND '17:00:00') 
  AND MINUTE(TIME(arrivalTime)) = 0 
  AND SECOND(TIME(arrivalTime)) = 0
  AND DAYNAME(arrivalTime) = 'Monday'

//编辑以回答评论

因此，您需要计算13:00-13.59、14:00-14:59等时段（例如）13:00-17:00之间的预订量

SELECT DAYNAME(arrivalTime) AS day, COUNT(arrivalTime) AS count, CONCAT(HOUR(arrivalTime), ':00 - ', HOUR(arrivalTime) + 1, ':00') as Hours
  FROM bookings
  WHERE (HOUR(arrivalTime) BETWEEN '13' AND '17')
  AND DAYNAME(arrivalTime) = 'Monday'
  GROUP BY HOUR(arrivalTime);

//编辑2

不幸的是，我现在没有时间修复我编写的查询，但是使用函数而不是单一选择（每一个小时进行一次选择）会更容易

但有两件事：

如果您希望从ex:10:00-17:00（ex:10:00-10:59）开始的每一小时都使用它，那么它将是所有在10:00和10:59之间具有拾取时间或到达时间的记录

如果你想从10:00-17:00这段时间里得到总数，它不会是一个总和，因为会有重复项，例如：10:00-10:59可能包含与11:00-11:59相同的记录

//编辑3

当您为日历的任何单元格调用此函数时，请检查此函数是否满足您的需要。如果要返回x而不是零，只需输入If并返回char。它的工作时间应为10:00-10:59（一小时周期）或10:00-16:59（总周期）

我不知道php，我知道.NET，但是如果你想让服务器返回一个完整的表，你可以简单地创建一个存储过程，在需要的地方调用这个函数，然后从php调用这个过程。我不是专家，但如果您希望服务器返回整个日历，则必须创建透视表

//编辑4（30-11-2015 00:04）

这里有一个用于单个单元格的函数和生成整个日历的存储过程，我添加了一个函数来评估提供日期的一周的第一天，因为您需要提供日期，否则它将返回所有的星期一，而不仅仅是您感兴趣的一周中的一天

用于评估单个单元格的函数：

arrivalTime - pickupTime 

13 - 15 (hours 13, 14 are counted)

10 - 14 (hours 10, 11, 12, 13 are counted)

16 - 17 (hours 16 are counted)

13 - 17 (hours 13, 14, 15, 16 are counted)

11 - 12 (hours 11 are counted)

代码可能有点多余，但我的时间确实很短。

我想即使在特定的时间内没有预订，您也需要计算一下。你需要一个小时的桌子来做这个

SELECT H.day_name AS day, 
       Count(b.arrivaltime) AS count 
FROM   hour_table H 
       LEFT OUTER JOIN bookings B 
                    ON h.day_name = Dayname(arrivaltime) 
                       AND h.hours = Hour(arrivaltime) 
WHERE  h.hours BETWEEN 13 AND 17 
       AND h.day_name = 'Monday' 
GROUP  BY H.day_name

编辑：如果您不想统计

X

和

Y

之间的所有预订。然后需要条件聚合。像这样的

Count(case when h.hours BETWEEN 13 AND 17 then b.arrivaltime .. end) AS count

当有足够的问题信息时，您可以添加完整答案

以使其更容易可视化这是我正在制作的日历：。这是我的数据库：。我不想让每个预订都检查X到17之间的计数，因为这会计算13:00到15:00之间的预订，对吗？所以即使16:00也会加上+1计数，这当然是不正确的。@LiamMacmillan-仍然不清楚。您可以添加示例记录和预期输出完成吗。希望能让我想要的更清楚一点。如果仍然不够清楚，我将在表中发布SQL数据，并提供预期的输出。嘿，你能检查我对MM93答案的评论吗？我相信是同样的问题。你想要这样的东西？不完全是因为它不够具体。看看我在问题上编辑了什么。嗯，我仍然在努力做到这一点。比我想象的要复杂得多。查看我的输入/预期输出，以便更好地了解我在寻找什么（我编辑了我的帖子）。我当前的查询可以很好地计算在某个时间开始的预订数量，但我需要这样做，以便每小时检查是否有其他预订超过该小时。请查看我所做的更新，我希望这是您正在寻找的。
