There is no way of doing it from the database. You can only do it from presentation tire. Upper() and lower() functions are not controlling the presentation. Those function change the data it self and send different string (e.g. if I run select upper(‘a’) it sends to the client the character A, it doesn’t send it as ‘a’ and tells the application to show it in a different way as ‘A’. You are asking for a function that will control the presentation of the data and there is no such function in the database.
