"13K" FROM DUAL;SELECT TO_CHAR(salary, '99G999D99L', 'NLS_NUMERIC_CHARACTERS = '',.''NLS_CURRENCY = ''EUR''') salary FROM employees;SELECT TO_CHAR(salary, '99G999D99C', 'NLS_NUMERIC_CHARACTERS = ''.,''NLS_ISO_CURRENCY = Japan') salary FROM employees;SELECT NLS_UPPER(last_name, 'NLS_SORT = Swiss') "Last Name" FROM employees;SELECT last_name FROM employeesORDER BY NLSSORT(last_name, 'NLS_SORT = German');Note: In some languages, some lowercase characters correspondto more than one uppercase character or vice versa. As a result, thelength of the output from the NLS_UPPER, NLS_LOWER, and NLS_INITCAP functions can differ from the length of the input.Working in a Global Environment 11-23
