如何在此过程中将小数小时转换为小时和分钟

Question

我有一个存储过程，返回4列数据

• Supporthoursworked（这是以分钟为单位返回并乘以60）
• SupportHoursCharged
• DevelopmentHoursWorked（也以分钟为单位返回并乘以）
• DevelopmentHoursCharged

我的问题是它目前以十进制形式返回这些值，并且很难将这些值转换为标准时间，

如何修改此程序以正确返回时间？

Answer 1

如果您希望它作为标准日期时间，您可以使用以下表达式：

dateadd(mi,SUM(SupportHoursWorked)*60,'00:00')  

如果你想要它“美丽”：

select CONVERT(VARCHAR(8), dateadd(mi,SUM(SupportHoursWorked)*60,'00:00'), 108) 'hh:mi:ss'

Answer 2

对于Sql Server 2012及以上：

SELECT timefromparts(SUM(SupportHoursWorked), 0, 0, 0, 0)

一般：

SELECT DATEADD(hh, SUM(SupportHoursWorked), CAST('00:00:00' AS TIME))

修改

替换：

Select 
  FromDate
, SUM(SupportHoursWorked)       AS SupportHoursWorked
, SUM(SupportHoursCharged)      AS SupportHoursCharged
, SUM(DevelopmentHoursWorked)   AS DevelopmentHoursWorked
, SUM(DevelopmentHoursCharged)  AS DevelopmentHoursCharged

使用：

Select 
  FromDate
, DATEADD(mi, SUM(SupportHoursWorked)*60 , CAST('00:00:00' AS TIME))      AS SupportHoursWorked
, DATEADD(mi, SUM(SupportHoursCharged)*60, CAST('00:00:00' AS TIME))      AS SupportHoursCharged
, DATEADD(mi, SUM(DevelopmentHoursWorked)*60, CAST('00:00:00' AS TIME))   AS DevelopmentHoursWorked
, DATEADD(mi, SUM(DevelopmentHoursCharged)*60, CAST('00:00:00' AS TIME))  AS DevelopmentHoursCharged

Answer 3

我认为这是一个简单的答案。尝试将它们转换为Time数据类型。时间打印出像hh：mm：ss [.nnnnnnn]
