如何将两个时间的长值差转换为秒?示例: Insert Time is 2021-07-28 13:22:05.742906 -> Epoch Value 1627459467906Difference between Insert and Update Time is -> 1627459516218- 1627459467906 = 48312
我在MySQL中查询了同样的东西,但这东西在使用pdo PHP的MS Access中不起作用。SELECT MachineNo, Empcardno, Date, SEC_TO_TIME(SUM(tsecs)) AS total_time SELECT CASE WHEN MachineNo(`Time`) END AS tsecs
FROM times
