What is UPPER?

UPPER is a string function that transforms all characters in a given string to uppercase. It accepts a single string or character-based column as an argument and returns a new string where every letter has been converted to its uppercase equivalent. Non-alphabetic characters and already uppercase characters remain unchanged.
