How It Affects Your App
The error indicates that the application is attempting to use a feature that is not supported by the current version of MySQL. This can lead to unexpected behavior and errors in the application, as the application may not be able to execute certain operations correctly. It can also lead to performance issues, as the application may not be able to execute certain operations in the expected amount of time. This can lead to a decrease in user experience and satisfaction.
