How It Affects Your App
The ER_FK_DEPTH_EXCEEDED error indicates that the application has exceeded the maximum number of foreign key constraints allowed by MySQL. This can cause the application to fail to execute queries, resulting in data integrity issues and unexpected behavior. It can also lead to performance issues, as the application may take longer to process queries due to the additional constraints. In addition, the application may be unable to access certain data due to the constraints, leading to incomplete results.
