A <code>NClob</code> object, just like a <code>Clob</code> object, is valid for the duration * of the transaction in which it was created. * Methods in the interfaces {@link ResultSet}, * {@link CallableStatement}, and {@link PreparedStatement}, such as * <code>getNClob</code> and <code>setNClob</code> allow a programmer to * access an SQL <code>NCLOB</code> value. In addition, this interface * has methods for updating a <code>NCLOB</code> value. * <p> * All methods on the <code>NClob</code> interface must be fully implemented if the * JDBC driver supports the data type. * * @since 1.6 */ public interface NClob extends Clob { }
