Doing a check on an old 8.7.11 latest patch server I come across this on mysql_error.log::
Code: Select all
2019-07-02 12:22:49 7f92de67cb00 InnoDB: Error: Column last_update in table "mysql"."innodb_table_stats" is INT UNSIGNED NOT NULL but should be BINARY(4) NOT NULL (type mismatch).
2019-07-02 12:22:49 7f92de67cb00 InnoDB: Error: Fetch of persistent statistics requested for table "mboxgroup98"."tombstone" but the required system tables mysql.innodb_table_stats and mysql.innodb_index_stats are not present or have unexpec
ted structure. Using transient stats instead.
Thanks
