Thank you

USE msdbUSE msdb


go
made the trick.

For make it easy to use I added after SELECT

DECLARE @DateFrom char(8) = '20170723' -- Set your start day range

DECLARE @DateTo char(8) = '20170725'-- Set your end day range

By the way I have uncommented, edited and added to the GROUP BY

sJobHis.run_time AS [Running_Time],

sJobHis.run_duration AS [Running_Duration],

But the result is unclear and not easy to understand. I mean the script is awesome but it doesn't show me the big picture:

Wouldn't be easier to show date like 'yyyy/mm/dd' and time like 'hh/mm/ss'?
Can you help me do that?
