Thread: Time formating

Hello All,

This question is related to my preceeding question.

How to format a value 7383 to represent 02H:03M:03SS (hours-minutes-seconds) 
using postgresql?

I have this query:

SELECT SUM (session_length))/60)/60 AS "Total",
FROM   user_sessions
WHERE  TO_CHAR(session_start, 'YYYY-MM') = '2003-04';

If session_length = 7383 I will receive 2.


I have received advice that I should use . and it will work with

select 5./2, however how to do it when I have a variable?

Thank you for your time.

Daniel

A better way would probably be something like:
SELECT INTERVAL '1 second' * session_length AS "Total"...

Use a cast of the general form CAST(<variable> as <type>).
