How It Affects Your App
The error 1693 ER_BINLOG_UNSAFE_MIXED_STATEMENT has a significant impact on an application. It indicates that the application is using a combination of transactional and non-transactional statements in the same transaction. This can lead to data inconsistency and data loss, as the non-transactional statements are not guaranteed to be executed in the same order as the transactional statements. Furthermore, the application may not be able to rollback the transaction if an error occurs, leading to further data inconsistency. Therefore, it is important to ensure that the application is using only transactional statements in a single transaction.
How To Fix
1. Check the error log for the MySQL 1693 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 server status to see if it is running:
$ mysqladmin status
4. Check the MySQL server version to ensure it is up to date:
$ mysqladmin version
5. Check the MySQL server process list to see if there are any long-running queries:
$ mysqladmin processlist
6. Check the MySQL server variables to see if any of them are set incorrectly:
$ mysqladmin variables
7. Check the MySQL server logs for any suspicious activity:
$ tail -f /var/log/mysql/mysql.log
8. Restart the MySQL server to reset any misconfigurations:
$ service mysql restart
