This is the first shot on problem (the simpliest way, to count this - no procedure, just math):

SELECT TO_CHAR(CALL_START + SUBSTR(CALL_DURATION,1,2)/24 + SUBSTR(CALL_DURATION,4,2)/(24*60) + SUBSTR(CALL_DURATION,7,2)/(24*3600), 'DD/MM/YYYY HH24:MI:SS') test
FROM DUAL;

I think there may be more advanced way to compute this but this works

Have a nice day,

I have the following table

CALL_START      CALL_DURATION
15/04/2010 10:05:13     00:02:15
Date    Varchar2


the first column type is date
the second column type is varchar2

I have an application record every call start time & its duration

I want to create a function or query to get the call end date&time which equal
CALL_START + CALL_DURATION

Best Regards,
Iyad
