如何使用T-SQL将Seconds转换为HH:MM:SS
情况是你在Seconds(XXX.XX)中有一个值,你想用T-SQL转换成HH:MM:SS。
例:
- 121.25秒变成00:02:01.25
由于小数部分被丢弃,您希望乘以毫秒。
SELECT DATEADD(ms, 121.25 * 1000, 0)
如果你想没有date部分,你可以使用CONVERT,风格114
SELECT CONVERT(varchar, DATEADD(ms, 121.25 * 1000, 0), 114)
如果您的时间量超过24小时 ,则无法通过DATEADD和CONVERT方法正确处理。
SELECT CONVERT(varchar, DATEADD(ms, 24*60*60 * 1000, 0), 114) 00:00:00:000
以下function将处理超过24小时(〜最大35,791,394小时)的时间。
create function [dbo].[ConvertTimeToHHMMSS] ( @time decimal(28,3), @unit varchar(20) ) returns varchar(20) as begin declare @seconds decimal(18,3), @minutes int, @hours int; if(@unit = 'hour' or @unit = 'hh' ) set @seconds = @time * 60 * 60; else if(@unit = 'minute' or @unit = 'mi' or @unit = 'n') set @seconds = @time * 60; else if(@unit = 'second' or @unit = 'ss' or @unit = 's') set @seconds = @time; else set @seconds = 0; -- unknown time units set @hours = convert(int, @seconds /60 / 60); set @minutes = convert(int, (@seconds / 60) - (@hours * 60 )); set @seconds = @seconds % 60; return convert(varchar(9), convert(int, @hours)) + ':' + right('00' + convert(varchar(2), convert(int, @minutes)), 2) + ':' + right('00' + convert(varchar(6), @seconds), 6) end
用法:
select dbo.ConvertTimeToHHMMSS(123, 's') select dbo.ConvertTimeToHHMMSS(96.999, 'mi') select dbo.ConvertTimeToHHMMSS(35791394.999, 'hh') 0:02:03.000 1:36:59.940 35791394:59:56.400
对于那些在超过24小时的时间内使用DATEADD和CONVERT有问题的人,我们可以使用模数来解决这个问题:
SELECT CONVERT(varchar, @seconds / 86400 ) + ':' + -- Days CONVERT(varchar, DATEADD(ms, ( @seconds % 86400 ) * 1000, 0), 114) as "Converted to D:HH:MM:SS.MS"
DECLARE @seconds AS int = 896434; SELECT CONVERT(varchar, (@seconds / 86400)) --Days + ':' + CONVERT(varchar, DATEADD(ss, @seconds, 0), 108); --Hours, Minutes, Seconds
输出:
10:09:00:34
使用SQL Server 05我可以通过使用这个工作:
declare @OrigValue int; set @OrigValue = 121.25; select replace(str(@OrigValue/3600,len(ltrim(@OrigValue/3600))+abs(sign(@OrigValue/359999)-1)) + ':' + str((@OrigValue/60)%60,2) + ':' + str(@OrigValue%60,2),' ','0')
使用SQL Server 2008
declare @Seconds as int = 3600; SELECT CONVERT(time(0), DATEADD(SECOND, @Seconds, 0)) as 'hh:mm:ss'
DECLARE @TimeinSecond INT SET @TimeinSecond = 340 -- Change the seconds SELECT RIGHT('0' + CAST(@TimeinSecond / 3600 AS VARCHAR),2) + ':' + RIGHT('0' + CAST((@TimeinSecond / 60) % 60 AS VARCHAR),2) + ':' + RIGHT('0' + CAST(@TimeinSecond % 60 AS VARCHAR),2)
这是我使用(通常为HTML表电子邮件报告)
declare @time int, @hms varchar(20) set @time = 12345 set @hms = cast(cast((@Time)/3600 as int) as varchar(3)) +':'+ right('0'+ cast(cast(((@Time)%3600)/60 as int) as varchar(2)),2) +':'+ right('0'+ cast(((@Time)%3600)%60 as varchar(2)),2) +' (hh:mm:ss)' select @hms
SELECT substring(convert (varchar(23),Dateadd(s,10000,LEFT(getdate(),11)),121),12,8)
10000是你的价值秒
DECLARE @Seconds INT = 86200; SELECT CONVERT(VARCHAR(15), CAST(CONVERT(VARCHAR(12), @Seconds / 60 / 60 % 24) +':'+ CONVERT(VARCHAR(2), @Seconds / 60 % 60) +':'+ CONVERT(VARCHAR(2), @Seconds % 60) AS TIME), 100) AS [HH:MM:SS (AM/PM)]
在select查询中将秒转换为小时:
SELECT field_in_seconds,round((field_in_seconds / 3600),2) FROM a_table;
这会给你十进制格式的结果。 不知道如何将1.50转换为1:30。 请随时编辑我的代码!
