我正在制作一个计划脚本，其中一周的开始时间是星期三，结束时间是星期二。我一直在研究并找到如何在星期三开始这一周，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。
我的代码现在正是七天中的每一天......

如果从日期开始减去某些天并选择产生的一周呢？
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

如何在周三开始这一周
所以基本上你只想把0到6范围内的一系列值“移动”给定的数字......这很容易：
$shifted_value = ( $actual_value + $offset ) % $number_of_values;
所以这里$offset将是4（星期三是PHP中一周的第3天，但减去 3可能导致模数除法产生不必要的负值 - 所以我们只是转移“进入未来”而非过去，添加 4 [= 7-3]）和$number_of_values将是7。
这将是PHP版本，在MySQL中它可以以相同的方式完成 - 只需要相应地调整偏移量，因为MySQL周三是第2周的第2天。
