How It Affects Your App
This error prevents the application from switching the SQL log bin on while inside a transaction. This can have a significant impact on the application as it prevents the application from logging changes to the database while inside a transaction. This can lead to data loss or corruption if the transaction is not completed successfully. It also prevents the application from being able to debug any issues that may arise while inside a transaction.
How To Fix
1. Check the error log for the MySQL 1694 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:

4. Check the MySQL user privileges and make sure they are set correctly:
$ mysql -u root -p
mysql> SHOW GRANTS FOR 'root'@'localhost';
5. Check the MySQL database tables and make sure they are not corrupted:
$ mysqlcheck -u root -p --all-databases
6. Check the MySQL server status and make sure it is running correctly:
$ mysqladmin -u root -p status
