SQL Server 2008 で整数 (時間) を HH:MM:SS::00 に変換する方法は?

declare @T int

set @T = 10455836
--set @T = 421151

select (@T / 1000000) % 100 as hour,
       (@T / 10000) % 100 as minute,
       (@T / 100) % 100 as second,
       (@T % 100) * 10 as millisecond

select dateadd(hour, (@T / 1000000) % 100,
       dateadd(minute, (@T / 10000) % 100,
       dateadd(second, (@T / 100) % 100,
       dateadd(millisecond, (@T % 100) * 10, cast('00:00:00' as time(2))))))  
  

 結果:
 
hour        minute      second      millisecond
