Sets the designated parameter to a Reader object. This method differs from the setCharacterStream (int, Reader) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be send to the server as a LONGNVARCHAR or a NCLOB

Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setNClob which takes a length parameter.

Parameters:

parameterName		the name of the parameter
reader		An object that contains the data to set the parameter value to.

Exceptions:

SQLException		if parameterName does not correspond to a named parameter; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs or this method is called on a closed CallableStatement
SQLFeatureNotSupportedException		if the JDBC driver does not support this method
