Observaciones
This updateNCharacterStream method is specified by the updateNCharacterStream method in the java.sql.ResultSet interface.
This method passes Unicode characters from a Reader object to selected nchar, nvarchar(max), ntext, and xml columns. Using this method on other data type columns will throw an exception.
If the length of the stream is different than what is specified in the length parameter, the JDBC driver throws an exception when the row is updated or inserted.
If the length of the stream is unknown, the length parameter may be set to -1 to indicate that the driver should accept the stream regardless of its length. With sqljdbc4.jar, we recommend that you use the JDBC 4.0 method updateNCharacterStream Method (int, java.io.Reader) when the application wants to update the column from a stream whose length is unknown.
