How It Affects Your App
MySQL 1125 ER_UDF_EXISTS indicates that a user-defined function (UDF) already exists. This error can prevent an application from creating a new UDF, which can have a significant impact on the application's functionality. If the application relies on UDFs to perform certain tasks, it may not be able to complete those tasks without the new UDF. Additionally, the application may not be able to access data stored in the existing UDF, which can lead to data loss or corruption.
