can a unique id be a string

Good Afternoon,  If I’m using a attribute and set it to auto increment we get the Id to 1,2,3 and so on. But I need the attribute to save a string kind of values like EMP_1, EMP_2, EMP_3 and so on. Is it possible in mendix to do this using any functions.

This is not natively possible in Mendix. But there should a way to achieve it. One idea that comes to mind is to have a separate string id in addition to the auto number which you would set when the object is created.

Hope this helps
