How to repeat:
step 1:
create the following table into MySQL database:

CREATE TABLE `Orders` (
  `orderID` int(11) NOT NULL,
  `description` varchar(50) DEFAULT NULL,
  `dataOrder` date DEFAULT NULL,
  `statusOrder` varchar(3) DEFAULT NULL,
  PRIMARY KEY (`orderID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

step 2:
create the following stored procedure into MySQL database:

CREATE DEFINER=`root`@`localhost` PROCEDURE `dbquery`.`cur_Orders`(pi_parametro INT)
BEGIN
	DECLARE s VARCHAR(20);
	
	IF pi_parametro = 1 THEN
		SELECT orderID,
			   description,
			   dataOrder,
			   statusOrder
		  FROM Orders
		 ORDER BY orderID;
 	ELSE 
		SELECT orderID,
			   description,
			   dataOrder,
			   statusOrder
		  FROM Orders
		 ORDER BY 3;
 	END IF;
END

step3: 
create java function like this:

private Connection  dbconn		= null;
private HttpSession datibasisessio	= null;
private Statement   stmt		= null;
private ResultSet   rs			= null;
boolean	is_rs				= false;
int tmp;

stmt = dbconn.prepareCall("{call cur_Orders(1)}",
                        ResultSet.TYPE_SCROLL_INSENSITIVE,
                        ResultSet.CONCUR_UPDATABLE,
                        ResultSet.CLOSE_CURSORS_AT_COMMIT);

is_rs = sql_propositio.execute();

if (is_rs == true) {
	rs = sql_propositio.getResultSet();
	tmp = rs.getConcurrency();			
}

rs.updateString(2, "ciao");
rs.updateRow();
