Sets the designated parameter to the given <code>Reader</code>
object, which is the given number of characters long.
When a very large UNICODE value is input to a <code>LONGVARCHAR</code>
parameter, it may be more practical to send it via a
<code>java.io.Reader</code> object. The data will be read from the stream
as needed until end-of-file is reached.  The JDBC driver will
do any necessary conversion from UNICODE to the database char format.

<P><B>Note:</B> This stream object can either be a standard
Java stream object or your own subclass that implements the
standard interface.

@param parameterName the name of the parameter
@param reader the <code>java.io.Reader</code> object that
       contains the UNICODE data used as the designated parameter
@param length the number of characters in the stream
@exception SQLException if a database access error occurs or
this method is called on a closed <code>CallableStatement</code>
@exception SQLFeatureNotSupportedException if the JDBC driver does not support
this method
