  31  * The mapping in the Java™ programming language
  32  * for the SQL <code>NCLOB</code> type.
  33  * An SQL <code>NCLOB</code> is a built-in type
  34  * that stores a Character Large Object using the National Character Set
  35  *  as a column value in a row of  a database table.
  36  * <P>The <code>NClob</code> interface extends the <code>Clob</code> interface
  37  * which provides provides methods for getting the
  38  * length of an SQL <code>NCLOB</code> value,
  39  * for materializing a <code>NCLOB</code> value on the client, and for
  40  * searching for a substring or <code>NCLOB</code> object within a
  41  * <code>NCLOB</code> value. A <code>NClob</code> object, just like a <code>Clob</code> object, is valid for the duration
  42  * of the transaction in which it was created.
  43  * Methods in the interfaces {@link ResultSet},
  44  * {@link CallableStatement}, and {@link PreparedStatement}, such as
  45  * <code>getNClob</code> and <code>setNClob</code> allow a programmer to
  46  * access an SQL <code>NCLOB</code> value.  In addition, this interface
  47  * has methods for updating a <code>NCLOB</code> value.
  48  * <p>
  49  * All methods on the <code>NClob</code> interface must be fully implemented if the
  50  * JDBC driver supports the data type.
  51  *
