java.sql.Clob, java.sql.NClobpublic class JDBCNClob extends JDBCClob implements java.sql.NClob
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.
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.
