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.
