I want to count total time in hh:mm:ss format. and I have minutes in int like (465). I made:

SQL

CONVERT(varchar, CONVERT(datetime, cast(cast(TotalMin/60 as int) as nvarchar(50)) + ' : ' + cast(TotalMin%60 as nvarchar(50))),108) AS TotalMin

but it shows below error. Not in SQL Server but when I run code in c#:

Conversion failed when converting date and/or time from character string.

Solution 1

Convert your final output to time format or use below code

SQL

select convert(time,cast((465 / 60) as varchar(2)) + ':' + cast((465 % 60) as varchar(2)),108)

SQL

select replace(cast((465 % 1440) as varchar(2)),'*','0') + ':' +cast((465 / 60) as varchar(2)) + ':' + cast((465 % 60) as varchar(2))

Your code is right but it returns "1@38@00" with list, " : " in place of " @ "

Solution 2

Try

SQL

Select (CASE WHEN LEN(CONVERT(VARCHAR,465/60)) = 1 THEN ('0' + CONVERT(VARCHAR,465/60)) ELSE CONVERT(VARCHAR,465/60) END) + ':' + CONVERT(VARCHAR,465%60) + + ':00'

Friend Your code is really right but when I show this records to reports It shows like "0@0@0" It shows "@" in place of ":".
