Question

我的表中有一个时间戳值，表示记录生成的时间。

我想知道使用MySQL生成记录之前的秒数，小时数和天数。换句话说，我们怎样才能找出MySQL，当前时间和时间戳值的秒，小时，日格式的时间差异？

Answer 1

试试这个

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

有关详细信息，请参阅date and time functions

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,
>            floor((((b.TIMEOFMSGRCVD-a.TIMEOFMSGRCVD)*24*60*60) -
>            floor(((b.TIMEOFMSGRCVD-a.TIMEOFMSGRCVD)*24*60*60)/3600)*3600)/60)
>            MINUTES,
>            round((((b.TIMEOFMSGRCVD-a.TIMEOFMSGRCVD)*24*60*60) -
>            floor(((b.TIMEOFMSGRCVD-a.TIMEOFMSGRCVD)*24*60*60)/3600)*3600 -
>            (floor((((b.TIMEOFMSGRCVD-a.TIMEOFMSGRCVD)*24*60*60) -
>            floor(((b.TIMEOFMSGRCVD-a.TIMEOFMSGRCVD)*24*60*60)/3600)*3600)/60)*60)
> ))
>           SECONDS    FROM (SELECT * FROM ATC.ATCMSG WHERE FLIGHTDATE=TO_CHAR(SYSDATE-1,'MMDDYY') AND EVENTTYPE='DES') a, (SELECT
> * FROM ATC.ATCMSG WHERE FLIGHTDATE=TO_CHAR(SYSDATE-1,'MMDDYY') AND EVENTTYPE='ARR') b WHERE A.CALLSIGN=B.CALLSIGN ORDER BY 4,5,6;
