Mysql 查询帮助获取确切的日期时间差

我有一个查询，它获取插入记录的时间和日期与当前日期之间的差异

这是一个例子

select
datediff(date(now()),'2012-04-15 16:14:59') as DateDifference,
timediff(now(), '2012-04-15 16:14:59') as TimeDifference

但这一次给了我以下结果：

日期差时差 5112:26:22

我真的很想知道两者的确切区别

例如：

5:8:24:22

其中5是一天，8:24:22是时间。

试试这个

SELECT floor((date1-date2)*24) || ' HOURS ' ||
mod(floor((date1-date2)*24*60),60) || ' MINUTES ' ||
mod(floor((date1-date2)*24*60*60),60) || ' SECS ' as time_difference
FROM dates;

其结果是：

Time Difference (seconds): 15
Time Difference (minutes): 1
Time Difference (hours): 0
Time Difference (days): 0

请尝试以下查询：

select 
date(now()) date1, 
date('2012-04-15 16:14:59') date2,
datediff(date(now()),'2012-04-15 16:14:59') as DateDifference,
TIME(now()) time1, 
TIME('2012-04-15 16:14:59') time2, 
timediff(TIME(now()), TIME('2012-04-15 16:14:59')) as TimeDifference

这将为您提供精确的差异和比较

希望这有帮助。

您到底想要什么？112:26:22不是5天8小时24分22秒，而是4天16小时24分22秒。您希望退回这两个选项中的哪一个？

select 
date(now()) date1, 
date('2012-04-15 16:14:59') date2,
datediff(date(now()),'2012-04-15 16:14:59') as DateDifference,
TIME(now()) time1, 
TIME('2012-04-15 16:14:59') time2, 
timediff(TIME(now()), TIME('2012-04-15 16:14:59')) as TimeDifference
