TO_NCHAR (datetime) converts a datetime or interval value of DATE, TIMESTAMP, TIMESTAMP WITH TIME ZONE, TIMESTAMP WITH LOCAL TIME ZONE, INTERVAL MONTH TO YEAR, or INTERVAL DAY TO SECOND data type from the database character set to the national character set.
The following example converts the order_date of all orders whose status is 9 to the national character set:
SELECT TO_NCHAR(ORDER_DATE) AS order_date FROM ORDERS WHERE ORDER_STATUS > 9 ORDER BY order_date; ORDER_DATE -------------------------------------------------------------------------- 06-DEC-99 02.22.34.225609 PM 13-SEP-99 10.19.00.654279 AM 14-SEP-99 09.53.40.223345 AM 26-JUN-00 10.19.43.190089 PM 27-JUN-00 09.53.32.335522 PM
