UPSHIFT Function
The UPSHIFT function upshifts characters. UPSHIFT 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 UPSHIFT function is equal to the result returned by the UPPER or
UCASE function.
UPSHIFT returns a string of fixed-length or variable-length character data, depending on the
data type of the input string.
