UPPER Function
UPPER Function
The UPPER function upshifts characters. UPPER can appear anywhere in a query
where a value can be used, such as in a select list, an ON clause, a WHERE clause, a
HAVING clause, a LIKE predicate, an expression, or as qualifying a new value in an
UPDATE or INSERT statement. The result returned by the UPPER function is equal to
the result returned by the UPSHIFT or UCASE function.
UPPER returns a string of either fixed-length or variable-length character data,
depending on the data type of the input string.
You cannot use the UPPER function on KANJI or KSC5601 operands.
character-expression
is an SQL character value expression that specifies a string of characters to
upshift. See Character Value Expressions on page 6-37.
