如何從當前時間和時間戳中找出以秒，小時，分鐘爲單位的時間差在mysql中

Question

我的表中有一個表示記錄生成時間的時間戳值。

我想知道使用MySQL生成記錄之前的秒數，小時數，天數。換句話說，我們如何才能找出以秒，小時，天的格式與當前時間的差異和MySQL中的時間戳值？

Answer 1

試試這個

SELECT TIMESTAMPDIFF (SECOND, CURDATE(), your_timestamp_field) from your_table;

Answer 2

> SELECT A.CALLSIGN,TO_CHAR(A.TIMEOFMSGRCVD ,'YYYYMMDDHH24MISS') 
> time_tmo,TO_CHAR(b.TIMEOFMSGRCVD ,'YYYYMMDDHH24MISS') time_arrival, 
> floor(((b.TIMEOFMSGRCVD-a.TIMEOFMSGRCVD)*24*60*60)/3600) 
>   HOURS,
