>>-UCASE--(--expression--)------------------------------------->< |
The schema is SYSFUN.
Returns a string in which all the characters have been converted to upper case characters. All characters in the expression are monocased. That is a-z are translated to A-Z, and characters with diacritical marks are translated to their upper case if they exist. For example, in code page 850, é maps to É, but ÿ is not mapped since code page 850 does not include &Ye..
The argument can be CHAR or VARCHAR.
The result of the function is VARCHAR(4000). The result can be null; if the argument is null, the result is the null value.
