How It Affects Your App
MySQL 1586 ER_DUP_ENTRY_WITH_KEY_NAME indicates that an attempt to insert a duplicate entry into a table has been made. This can have a significant impact on an application as it can lead to data integrity issues, as well as data loss. It can also cause the application to crash or become unresponsive, as the database will not be able to process the query. Additionally, it can lead to incorrect results being returned from the database, as the duplicate entry will be ignored.
