parsing_user_id vs parsing_schema_id in dba_hist_sqlstat
hi,
1)
anyone know the difference between parsing_user_id and parsing_schema_id in dba_hist_sqlstat?
i.e. schema id vs user id, aren't they the same or is user_id related to instrumentation
2)
Also I can see PARSING_SCHEMA_NAME but no PARSING_USER_NAME in DBA_HIST_SQLSTAT, so why is PARSING_USER_NAME missing?
Thanks
