About options => 'GATHER AUTO' from dbms_stats
The documentation says:
When GATHER AUTO
is specified, the only additional valid parameters are ownname
, stattab
, statid
, objlist
and statown
; all other parameter settings are ignored. Returns a list of processed objects.
Is this right? I can't even define estimate_percent
and degree
?
I have tested in my lab, but I am not sure about the degree.
How can I check the current operation degree?estimate_percent
seems to have been ignored.
