SQL by Hourly break down

Experts -

How can I convert the output of this SQL into a hourly format based on logon time or start_exec time? Is that possible to convert the CPU_THIS_CALL to %CPU utilization?

Thanks,
Sve.

What do you mean by "a hourly format" ?

a single session belongs only to 1 hour ( to_char(trunc(LOGON_TIME),'HH24')
so i expect you want some accumulation of  data per hour : what accumulation ?

what percentage do you mean ?
round((stat.cpu - stat.CPU_this_call_start) * 100 / stat.cpu),0)  ?

Providing the procedure isn't enough to evaluate your request.  You have several functions with unknown use and without some insight into your data I'd be fumbling around in the dark.  I'm sure that grouping by HOUR(LOGON_TIME) is possible but don't have enough to go on at this point.

Thanks for your time. This SQL can run on any oracle environment, if you would like to know about the data.

Then please request that the SQL Server topic be removed.  It just creates confusion.
