How It Affects Your App

MySQL 1280 ER_WRONG_NAME_FOR_INDEX indicates that an index name is invalid or too long. This can cause the application to fail when attempting to create or modify an index. It can also lead to unexpected results when querying the database, as the index may not be used correctly. This can lead to incorrect data being returned or incorrect calculations being made. In addition, it can cause performance issues as the query optimizer may not be able to use the index correctly.
