php/mysql在星期二和星期二的一周的最后一天开始一周中的某一天

我正在制定一个时间表脚本，其中星期三的开始时间是星期三，结束时间是星期二。我一直在研究各地，并找到如何在周三开始，但最后一天总是在星期六或星期日结束，取决于使用DAYOFWEEK或WEEKDAY。php/mysql在星期二和星期二的一周的最后一天开始一周中的某一天

我的代码是正确的，现在的每七天...

哇。这是一系列if块中的一个。你不能每天都应用一个偏移量吗？你知道星期日是什么被认为是一周的开始，所以转移一切的恒定偏移量3. – crush

是的，我试过了...... 我在前一周做了额外的计划时间，当我做偏移它显示要么没有或前一周 –

如何开始的一周，周三

所以基本上你只是想“转移”值范围从0到6给定数目的......嗯，这是非常简单：

$shifted_value = ($actual_value + $offset) % $number_of_values;

所以这里$offset将是4（周三是在PHP星期几＃3，但减去 3可能会导致不必要的负值与模分割 - 所以我们只是将“进入未来”而不是过去，通过加 4 [= 7-3]）和$number_of_values将是7.

这将是PHP版本，在MySQL中它可以以同样的方式完成 - 只有偏移量必须根据事实进行调整，因为MySQL星期三是本周的第2天。

所以我把它放入mysql中如何选择？ \t $星期四=请求mysql_query（“SELECT h.timestart，h.timeend，h.work，h.why_off，h.work_type，h.date从数小时AS小时，员工为E \t \t \t \t \t \t其中h。 S_ID = ' “$ S_ID。”' AND e.u_id = h.u_id AND DAYOFWEEK（h.date）= 5 \t \t \t \t \t \t GROUP BY e.emp_id \t \t \t \t \t \t ORDER BY即emp_id ASC“）; –

我现在看到您似乎在为每个（工作）工作日进行单个查询 - 这相当复杂，您应该也可以使用“移位值”作为第二个（或第一个，取决于您希望如何循环数据）ORDER BY标准，而不是将其放入WHERE子句中，因此您可以在_one_查询中获取_all_ weekdays的相关数据。 – CBroe

我尝试过，并不确定如何正确写入... –

如何从日期减少某些日子并选择最后一周？

SELECT h.* FROM hours AS h, employees AS e 
WHERE h.s_id = '" .$s_id. "' AND e.u_id = h.u_id AND 
    WEEK(DATE_ADD(h.date, INTERVAL -3 DAY)) = 4 
ORDER BY h.date, e.emp_id ASC

无济于事。 –

日期函数在[MySQL 4.1]（https://dev.mysql.com/doc/refman/4.1/en/date-and-time-functions.html#function_date-add）中可用。你不能做'ORDER BY DAYOFWEEK（DATE_ADD（h.date，INTERVAL -3 DAY）），e.emp_id'以便在星期几之前对所有empoyees进行排序？ –

php/mysql在星期二和星期二的一周的最后一天开始一周中的某一天
