How It Affects Your App
The error ER_NO_TRIGGERS_ON_SYSTEM_SCHEMA indicates that triggers cannot be created on system schemas. This means that the application cannot use triggers to automate certain tasks, such as data validation or data manipulation. This can have a significant impact on the application, as it may not be able to perform certain tasks as efficiently as it could with triggers. Additionally, the application may not be able to take advantage of certain features that require triggers, such as data auditing or data synchronization.
How To Fix
