How It Affects Your App
MySQL 1393 ER_VIEW_MULTIUPDATE prevents an application from performing multiple updates on a view. This can be a major limitation for applications that rely on views to update multiple tables at once. It can also cause applications to become inefficient, as they may need to perform multiple updates on different tables instead of one update on a view. This can lead to longer processing times and more resources being used.
How To Fix
1. Check the error log for the MySQL 1393 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for the max_allowed_packet setting:
$ grep max_allowed_packet /etc/mysql/my.cnf
3. Increase the max_allowed_packet setting to a higher value:
max_allowed_packet = 16M
4. Restart the MySQL server:
$ sudo service mysql restart
5. Check the error log again to make sure the MySQL 1393 error is gone:
$ tail -f /var/log/mysql/error.log
6. Use an automated database observability tool to monitor and fix the MySQL 1393 in question. Automated database observability tools can provide real-time insights into the performance and health of your database, allowing you to quickly identify and fix any issues that arise.
