I have tried to find a blog or forum for the following issue, if someone could provide a link or the code, it would be greatly appreciated.
I have a column that is an int field and it holds the number of seconds that corresponds to a time during the day.
Example being that 24331 will be 6:45:31 AM and 67531 will be 6:45:31 PM. I'm looking for code that will show the time in AM/PM format and with the AM and PM at the end of time.
Thank you for the assistance and I apologize for the duplicate post, since I'm sure there is something out here already answering this question

You could do something like this. Just be mindful if you have any values that exceeds 24hrs (in seconds).

DECLARE @seconds INT

SET @seconds = 24331

IF @seconds < 43200

SELECT CAST(@seconds/3600 AS VARCHAR) + ':' + RIGHT('00' + CAST(@seconds%3600/60 AS VARCHAR),2) + ':' + RIGHT('00' + CAST(@seconds%60 AS VARCHAR),2) + ' AM' AS [time]

ELSE

SELECT CAST((@seconds/3600)-12 AS VARCHAR) + ':' + RIGHT('00' + CAST(@seconds%3600/60 AS VARCHAR),2) + ':' + RIGHT('00' + CAST(@seconds%60 AS VARCHAR),2) + ' PM' AS [time]

there's 86400 seconds in the day.

anything prior to exactly half that, (12:00:00) , or 43200 seconds, is AM, else PM

so a CASE WHEN seconds <43200 THEN 'AM' ELSE 'PM' END would work.

if you are using actual time or datetime datatypes, you can use the convert functions to show it, or use dateadd functions and use the math from above.

for example SELECT CONVERT(VARCHAR,getdate(),109) contains the AM/PM indicator for a datetime field.

what is your source of the seconds?

If you can guarantee a value that never exceeds 86,400 then you can use the following:

WITH INT_VALUES AS (

SELECT SecondsValue = 23641 UNION ALL

SELECT 43641

)

SELECT SUBSTRING(CONVERT(VARCHAR, CAST(SecondsValue / 86400. AS datetime),109), 13, 8) + ' ' +

RIGHT(CONVERT(VARCHAR, CAST(SecondsValue / 86400. AS datetime),109), 2) AS TIME_VALUE

FROM INT_VALUES;

EDIT: fixed the SQL where a couple of typos lopped off a bunch of the code and changed the style number for the CONVERT.

There's no need to stick to less than 86,400 seconds. Your code works fine for higher values too.

An alternative to using division and cast is to use a datetime constand and addition:-

WITH INT_VALUES AS (

SELECT SecondsValue = 23641 UNION ALL

SELECT 43641 UNION ALL

SELECT 110041 UNION ALL

SELECT 130041

)SELECT SUBSTRING(CONVERT(VARCHAR, CAST(SecondsValue / 86400. AS datetime),100), 12, 8) AS TIME_VALUE

FROM INT_VALUES

I think it's a bit more obvious what's happening in this version.

SELECT 130041

)

select replace(right(convert(varchar,dateadd(second, SecondsValue % 86400,0), 109), 14),':000',' ') from INT_VALUES;
