How It Affects Your App
MySQL 3102 ER_GENERATED_COLUMN_FUNCTION_IS_NOT_ALLOWED indicates that the application is attempting to use a function that is not allowed in a generated column. This can prevent the application from properly executing queries and updating data, resulting in unexpected behavior. It can also lead to data integrity issues, as the application may not be able to properly store and retrieve data. In addition, it can cause performance issues, as the application may be unable to properly optimize queries.
How To Fix
1. Check the error log for the MySQL 3102 error. This can be done by running the following command:
tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations. This can be done by running the following command:

3. Check the MySQL process list for any suspicious processes. This can be done by running the following command:

5. Check the MySQL grant tables for any suspicious grants. This can be done by running the following command:

6. Check the MySQL system variables for any suspicious settings. This can be done by running the following command:

7. Check the MySQL system status for any suspicious settings. This can be done by running the following command:
