To_char (run.end_date, ' rrrr-mm-dd HH24:MI:SS ') Completion time
From Ad_patch_runs Run,
Ad_patch_driver_langs Lang,
Ad_patch_drivers driver,
Ad_applied_patches applied
WHERE run.patch_driver_id = driver.patch_driver_id
and driver.applied_patch_id = applied.applied_patch_id
and lang.patch_driver_id = driver.patch_driver_id ORDER by 3,4,1,2
-You can count the time of patch, which is helpful to the time and schedule of patches for the product environment.
