How to convert frames into hours:minutes:seconds?

Question

if I have some columns which contains the time value in frames, i.e. Content_Duration, program_duration etc.
How can I convert those frames in hh:mm:ss?
Is it possible to do it with a function do that so that I can re-use it?
Thanks

I am not quite sure where you get content_interval from?CONTENT_INTERVAL comes from the function call "numtodsinterval( content_duration / 1500, 'MINUTE' )" in the inline view.
You might want to code it as "numtodsinterval( content_duration / 25, 'SECOND' )" to match the 25 frames/second standard you mentioned after I posted my reply.
will it allow more than 99 hours? i.e. 154:57:40?Actually, it won't work for more than 23 hours, 59 minutes, 59 seconds. For larger numbers this technique requires a field for the number of days, like this.
SQL*Plus: Release 10.2.0.1.0 - Production on Fri Jun 29 12:41:38 2007
create table t ( content_duration number );
Table created.
insert into t values ( 1500*60*99 /* = 99 hours */ );
1 row created.
commit;
Commit complete.
select
  lpad(extract(DAY    from content_interval),2,'0')||' '||
  lpad(extract(HOUR   from content_interval),2,'0')||':'||
  lpad(extract(MINUTE from content_interval),2,'0')||':'||
  lpad(extract(SECOND from content_interval),2,'0')
  as result
from
  ( select numtodsinterval( content_duration / 25, 'SECOND' ) as content_interval
    from t
RESULT
04 03:00:00
1 row selected.
-- if you're going to show DAYS though, the following way is simpler
select
  cast
  ( numtodsinterval( content_duration / 25, 'SECOND' ) as interval day(2) to second(0))
  as result
from t ;
RESULT
+04 03:00:00
1 row selected.If you really need output like 99:00:00 instead of +04 03:00:00 then take Volder's approach.
Is it possible to do it as a function?Anything you can do with a SQL query you can probably do inside a function, but for a line of code like "cast ( numtodsinterval( ..." I personally wouldn't bother.
