Sets the designated parameter to the given Reader object. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via a 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.

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



the name of the parameter


the object that contains the Unicode data


SQLException - if a database access error occurs, parameterName is not a valid parameter name, or the prepared statement has been closed
