Question

尝试查找每天两次时间戳之间预订资源的总时间-假设08:00-16:00。

到目前为止，我想出了这个解决方案，但是它没有按预期工作。我知道为什么它不起作用，但是我不确定如何从这里过渡到有效的SQL。

SELECT bookingresource.resourceID, SEC_TO_TIME(SUM(TIME_TO_SEC(booking.bookingEndDatetime) - TIME_TO_SEC(booking.bookingStartDatetime))) AS totalTimeBooked 
FROM booking, bookingresource 
WHERE booking.bookingID =  bookingresource.bookingID
AND bookingresource.bookingStartDatetime BETWEEN '2019-03-11 00:00:00' AND '2019-03-11 23:59:59'
AND HOUR(bookingresource.bookingStartDatetime) BETWEEN 8 AND 16 
AND HOUR(bookingresource.bookingEndDatetime) BETWEEN 8 AND 16
AND booking.companyID = 2447 AND bookingresource.`resourceID` = 807
GROUP BY bookingresource.resourceID

通过这种方式，我不包括不希望在8-16岁开始或结束的预订。如何包含部分预订时间在08：00-16：00之间的预订，并且仅计算08:00-16:00内的预订时间。

编辑：我将尝试简化SQL，因此没有太多不必要的代码。现在我的问题是总时间的计算方式。目前，如果预订部分在时间范围内，那么它将包括时间范围之外的时间。

SELECT bookingresource.resourceID, SEC_TO_TIME(SUM(TIME_TO_SEC(booking.bookingEndDatetime) - TIME_TO_SEC(booking.bookingStartDatetime))) AS timediff FROM booking, bookingresource 
WHERE booking.bookingID =  bookingresource.bookingID
AND (HOUR(bookingresource.bookingStartDatetime) BETWEEN 8 AND 16 
OR HOUR(bookingresource.bookingEndDatetime) BETWEEN 8 AND 16)
GROUP BY bookingresource.resourceID

编辑2：所以我找到了一个解决方案，但预订超过一天的订单却遇到了问题。到目前为止，这是我的解决方案：

SELECT bookingresource.resourceID, SEC_TO_TIME(sum(LEAST(TIME_TO_SEC(TIME(booking.bookingEndDatetime)), TIME_TO_SEC('16:00')) - GREATEST(TIME_TO_SEC(TIME(booking.bookingStartDatetime)), TIME_TO_SEC('08:00')))) AS totalTimeBooked FROM booking, bookingresource 
WHERE booking.bookingID =  bookingresource.bookingID
AND bookingresource.bookingStartDatetime BETWEEN '2019-04-10 00:00:00' AND '2019-04-10 23:59:59'
AND (TIME(bookingresource.bookingStartDatetime) BETWEEN '08:00' AND '16:00' 
OR TIME(bookingresource.bookingEndDatetime) BETWEEN '08:00' AND '16:00')
  AND bookingresource.`resourceID` = 453
  group by bookingresource.resourceID

Answer 1

Try convert you string date in proper datetime value

and if you don't want values outside the range 8 - 16 then you should also check that the date for star and end is the same

  SELECT bookingresource.resourceID
    , SEC_TO_TIME(SUM(TIME_TO_SEC(booking.bookingEndDatetime) - TIME_TO_SEC(booking.bookingStartDatetime))) AS totalTimeBooked 
  FROM booking
  INNER JOIN  bookingresource  ON booking.bookingID =  bookingresource.bookingID
  WHERE  bookingresource.bookingStartDatetime BETWEEN str_to_date('2019-03-11 00:80:00', '%Y-%m-%d %T') 
        AND str_to_date('2019-03-11 23:59:59', '%Y-%m-%d %T') 
  AND HOUR(bookingresource.bookingStartDatetime) BETWEEN 8 AND 16 
  AND HOUR(bookingresource.bookingEndDatetime) BETWEEN 8 AND 16
  AND DATE(bookingresource.bookingStartDatetime) = DATE(bookingresource.bookingEndDatetime)
  AND booking.companyID = 2447 
  AND bookingresource.`resourceID` = 807
  GROUP BY bookingresource.resourceID

如何在资源上查找08：00-16：00之间的总预订时间
