The MySQL Workbench program is very useful when managing both MySQL and MariaDB databases, but it is possible that we have encountered the following error.
Unknown table 'COLUMN_STATISTICS' in information_schema (1109)
To fix this error we must modify the MySQL Workbench file wb_admin_export.py.
We look for the line containing "skip_column_statistics = True" and comment out the subsequent condition.
Restart the program and it should work correctly.
