Hello Martin, There's not much hint to it, here's a solution instead :)
You can make use of several built-in functions to handle strings, date/time values etc. Take a look at chapter 9: Functions and Operators of your PostgreSQL documentation all available functions are explained there. To solve my problem I used the extract EXTRACT (field FROM source) function, as described in paragraph 9.8.1. You can use it to extract a certain field form your timestamp vield, for example: extract (hour from timestamp '2004-16-04 09:21:52') returns 9 SELECT EXTRACT(EPOCH FROM INTERVAL '5 days 3 hours'); Result: 442800 EPOCH will return the number of seconds. You can multiply those by n*60, depending if you want minutes or hours. At first I used a different calculation, but this one should be less work :). I hope you're problem is solved that way. I took the liberty of CC-ing the postgresql mailinglist so other's having a similar problem can read about this solution too. It's all about the (open-source)-community isn't it :) Kind regards, Stijn Vanroye -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: dinsdag 15 juni 2004 19:08 To: Stijn Vanroye Subject: Your question in postgresql.org forum Hello Stijn, I read your question in postgresql.org forum published under sunject "Difference between two times as a numeric value in a stored procedure" I am currently solving the same problem...
