UPPER scalar function
The UPPER function is identical to the TRANSLATE function except that only the first argument (char-string-exp) is specified.
The schema is SYSIBM. (The SYSFUN version of this function continues to be available for upward compatibility.)
- An expression that returns a built-in character string that is not FOR BIT DATA. In a Unicode database, the expression can also return a graphic string, in which case it is first converted to a character string before the function is evaluated.
