在存储过程中将HH:MM:SS:Msec转换为HH:MM:SS [英] HH:MM:SS:Msec to HH:MM:SS in stored procedure

问题描述

我有一个存储过程，该存储过程会基于这种计算来更新表，并且该计算以列名(日历)-(当前系统日期时间)完成，并将此信息更新为列(TimeSpent)并以Hh显示值:Mm:SS:Msec格式.查询工作正常，但我想以某种方式进行更新，以使花费的时间应仅为HH:MM:SS格式.请帮助我，我如何从所花费的时间中删除该Msec.

I have a stored procedure which update a table based on such calculation and the calculation is done as Column Name (Calendatedate) -( Current System Date Time) and update this information to a column (TimeSpent) and display the value in Hh:Mm:SS:Msec Format. The Query is working fine but i want to update it in such a way so that the Time spent should be only HH:MM:SS Format.Please help me that how i remove that Msec From the time Spent.

CREATE procedure St_Proc_UpdateTimeSpent        
@timeEntryID int,        
@status int output        
as begin         
set nocount on;        
declare @Date dateTime;        
set @Date=GETDATE(); 
	update Production set TimeSpent=(SELECT CONVERT(VARCHAR(20),DateAdd(SS,Datediff(ss,CalendarDate, @Date)%(60*60*24),0),114)),  
	IsTaskCompleted=1       
	where productionTimeEntryID=@timeEntryID         
	set @status=1;        
	return @status;        
end

推荐答案

在CONVERT函数中尝试使用108而不是114来仅获取hh :mm:ss格式.

参考: MSDN:CAST和CONVERT(Transact-SQL) [

Try 108 instead of 114 in the CONVERT function to get only the hh:mm:ss format.

Refer: MSDN: CAST and CONVERT (Transact-SQL)[^]
