How It Affects Your App
MySQL 1560 ER_STORED_FUNCTION_PREVENTS_SWITCH_BINLOG_FORMAT prevents the application from switching to a different binary log format. This can cause issues with replication, as the application may not be able to replicate data correctly. It can also cause issues with backups, as the application may not be able to back up data correctly. This can lead to data loss or corruption, which can have a significant impact on the application.
