Table stats gathered without data changes
Version: 19.23 EE
I imported stats into a database from a well tested database for all the tables under a owner where there was no data load yet (0 rows for all the tables).
However, I checked today and 3 tables still with 0 rows but got reanalyzed with 0 rows.
Without data change (default stale percent: 10%), wonder why only a few tables stats got gathered, but the rest are still with imported stats.
Details: We have not set table_prefs for any tables. No high frequency stats turned on. overnight auto stats gathering.
Looking for ideals as to why only a few tables stats regathered without data changes.
