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 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.
HSQLDB-Specific Information:
First, it should be noted that since HSQLDB represents all character data internally as Java UNICODE (UTF16) String objects, there is not currently any appreciable difference between the HSQLDB XXXCHAR types and the SQL 2003 NXXXCHAR and NCLOB types.
See JDBCClob
for further information.
