MySQL 3218

This error occurs when an invalid value is passed as an argument for the maximum array length in the MySQL audit log UDF read.

How It Affects Your App

This error indicates that an invalid maximum array length argument value was used when attempting to read from the audit log using a user-defined function. This can cause the application to fail to read the audit log correctly, resulting in incorrect or incomplete data being retrieved. This can lead to incorrect decisions being made based on the data, or the application being unable to perform certain tasks. In addition, the application may be unable to detect any malicious activity that has occurred.
