public interface NClob extends Clob
NCLOB type.
An SQL NCLOB is a built-in type
that stores a Character Large Object using the National Character Set
as a column value in a row of a database table.
The NClob interface extends the Clob interface
which provides provides methods for getting the
length of an SQL NCLOB value,
for materializing a NCLOB value on the client, and for
searching for a substring or NCLOB object within a
NCLOB value. A NClob object, just like a Clob object, is valid for the duration
of the transaction in which it was created.
Methods in the interfaces ResultSet,
CallableStatement, and PreparedStatement, such as
getNClob and setNClob allow a programmer to
access an SQL NCLOB value. In addition, this interface
has methods for updating a NCLOB value.
All methods on the NClob interface must be fully implemented if the
JDBC driver supports the data type.
