我有一个查询,从插入记录的时间到当前日期的时间和日期不同。
以下是示例。
select
datediff(date(now()),'2012-04-15 16:14:59') as DateDifference,
timediff(now(), '2012-04-15 16:14:59') as TimeDifference
但是这个给我以下结果:
日期差异时差 5 112:26:22
我真的希望得到两者之间的确切差异。
示例:
5 8:24:22
其中5是日,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;
答案 1 :(得分:0)
DateTime startTime = DateTime.Now;
DateTime endTime = DateTime.Now.AddSeconds( 75 );
TimeSpan span = endTime.Subtract ( startTime );
Console.WriteLine( "Time Difference (seconds): " + span.Seconds );
Console.WriteLine( "Time Difference (minutes): " + span.Minutes );
Console.WriteLine( "Time Difference (hours): " + span.Hours );
Console.WriteLine( "Time Difference (days): " + span.Days );
输出结果为:
Time Difference (seconds): 15
Time Difference (minutes): 1
Time Difference (hours): 0
Time Difference (days): 0
答案 2 :(得分:0)
尝试此查询:
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
这将为您提供准确的差异和比较。
希望这有帮助。
