我遇到了timediff
和的问题DATE_SUB
。这是我的 MYSQL 查询:
SELECT id, clock_user_id, clock_date,
(Select clock_time from aura_clock where aura_clock.clock_type = 'Start' and
aura_clock.clock_date = t1.clock_date) as start, (Select clock_time
from aura_clock where aura_clock.clock_type = 'Stop'
and aura_clock.clock_date =
t1.clock_date) as Stop,
问题从这里开始
TIMEDIFF((select clock_time FROM aura_clock t
WHERE t.clock_date = t1.clock_date AND t.clock_time > t1.clock_time
ORDER BY t.clock_time LIMIT 1), MIN(clock_time)) as spent
FROM aura_clock t1 WHERE t1.clock_date >= DATE_SUB(DATE_SUB(CURDATE(), INTERVAL
WEEKDAY(CURDATE()) DAY),INTERVAL 15 day)
AND t1.clock_date < DATE_SUB(curdate(),INTERVAL DAYOFWEEK(curdate()) + 6 day)
GROUP BY clock_date
结果是:
现在,我想从使用时间中减去 1 小时,DATE_SUB
但它没有用。
