How It Affects Your App
The error ER_CANNOT_LOAD_FROM_TABLE_V2 indicates that the application is unable to load data from a table in MySQL. This can have a significant impact on the application, as it may be unable to access the data it needs to function properly. This can lead to the application not working as expected, or even crashing. It can also lead to data loss, as the application may not be able to save data to the table. This can be a major issue for applications that rely on data stored in MySQL.
How To Fix
1. Check the error log for the MySQL 1728 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:
$ cat /etc/mysql/my.cnf
3. Check the MySQL process list to see if any processes are running that shouldn't be:
$ mysqladmin -u root -p processlist
4. Check the MySQL user table to see if any users have been added that shouldn't be:
$ mysql -u root -p -e "SELECT * FROM mysql.user;"
5. Check the MySQL grant tables to see if any privileges have been granted that shouldn't be:
$ mysql -u root -p -e "SELECT * FROM mysql.db;"
6. Check the MySQL system variables to see if any variables have been set that shouldn't be:
$ mysql -u root -p -e "SHOW VARIABLES;"
7. Use an automated database observability tool to monitor and fix the MySQL 1728 in question. Automated database observability tools can provide real-time visibility into the performance and health of your database, allowing you to quickly identify and fix any issues that arise.
