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 fixed-length or variable-length character data, depending on the data
type of the input string.
UPPER (character-expression)
character-expression
is an SQL character value expression that specifies a string of characters to upshift. See
