Convert Millisecond To "hh:mm:ss" Format

This question was posted in the Transact-SQL MSDN Forum
You have a column in your table that stores duration in milliseconds
You would like to output this in the following format ‘hh:mm:ss’
So for example 11354013 would be 03:09:14:013 and 86399998 milliseconds would be 23:59:59:997 But be careful because 86399998 will return 23:59:59:997 but 86399999 will return 00:00:00:000 (it will round up to 1 day, 0 hours etc etc)

So let’s see how to do that. Basically all you have to do is add the milliseconds to a zero date and then convert that to varchar with a style of 114 (hh:mi:ss:mmm(24h))

DECLARE @SomeMilliSecondsNumber INT
SELECT @SomeMilliSecondsNumber =11354013

SELECT CONVERT(VARCHAR,DATEADD(ms,@SomeMilliSecondsNumber,0),114)
--03:09:14:013
GO


DECLARE @SomeMilliSecondsNumber INT
SELECT @SomeMilliSecondsNumber =86399998

SELECT CONVERT(VARCHAR,DATEADD(ms,@SomeMilliSecondsNumber,0),114)
--23:59:59:997
GO

DECLARE @SomeMilliSecondsNumber INT
SELECT @SomeMilliSecondsNumber =86399999

SELECT CONVERT(VARCHAR,DATEADD(ms,@SomeMilliSecondsNumber,0),114)
--00:00:00:000
GO

    SELECT CONVERT(VARCHAR,DATEADD(ms,@SomeMilliSecondsNumber,0),114)

    Could you post an example of the values or charater strings you would use in place of "VARCHAR" "DATEADD" or "@someMilliSecondsNumber" ?

    Thanks I'm a begginer trying to convert from milliseconds to HH:MM:SS, I know thats conversion 108 not 114.
