LCASE Function
LCASE Function
The LCASE function downshifts characters. LCASE 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 LCASE function is equal to
the result returned by the LOWER function.
LCASE 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 LCASE function on KANJI or KSC5601 operands.
LCASE is an SQL/MX extension.
character-expression
is an SQL character value expression that specifies a string of characters to
downshift. See Character Value Expressions on page 6-37.
