MySQL 3135

This error occurs when attempting to set a SQL mode that is incompatible with the existing mode. It indicates that the modes have been merged to ensure compatibility.

How It Affects Your App

MySQL 3135 ER_SQL_MODE_MERGED affects the application by preventing the use of certain SQL modes. This can lead to unexpected behavior when running queries, such as errors when attempting to insert invalid values into a table. Additionally, it can cause queries to fail if the syntax is not compatible with the SQL mode being used. This can lead to data integrity issues and unexpected results when running queries.

How To Fix

1. Check the error log for the MySQL 3135 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 3135 error is gone:
$ tail -f /var/log/mysql/error.log
6. Use an automated database observability tool to monitor and fix the MySQL 3135 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.
