Convert time to string - SQL

Scenario where a db field contains seconds, the user wanted a SSRS report displaying various aggregates of the seconds field as Hours - Minutes - Seconds.


IFOBJECT_ID('dbo.udf_SCC_TimeToString') IS NOT NULL
DROP FUNCTION dbo.udf_SCC_TimeToString ;
GO

CREATE
FUNCTION dbo.udf_SCC_TimeToString
(
@timesec INT) --input in seconds as integer

RETURNSVARCHAR(25)

AS

 
BEGIN
DECLARE

@return
AS VARCHAR(25),

@a AS INT,

@b AS INT,

@hours AS INT,

@mins AS INT,

@secs AS INT;

SET@a = @timesec%3600 --get no. of seconds over the hour

SET@hours = (@timesec - @a)/3600 --get no. of seconds of completed hours, divide by hour in seconds to get completed hours

SET@b = @a --hold no. of secs over the hour

SET@a = @b%60--get no. of secs over the min

SET@mins = (@b - @a)/60 --get no. of seconds of completed mins, divide by min in secs to get completed minutes

SET@secs = @a

SET@return =

CASE
 
WHEN @timesec >=3600

THEN
 
convert(varchar(10),@hours) + ' hr ' +

convert(varchar(10),@mins) + ' min ' +

convert(varchar(10),@secs) + ' sec '

WHEN @timesec >=60

THEN

convert(varchar(10),@mins) + ' min ' +

convert(varchar(10),@secs) + ' sec '

ELSE

convert(varchar(10),@secs) + ' sec '

END;

RETURN
@return

END
