MySQL Java stored procedure gives error "Parameter index of 1 is out of range"

Question

public static void main(String[] args) throws Exception {
        Connection connection = getMySqlConnection();
        CallableStatement proc = connection.prepareCall("{ call LCD_GetDispInfoAllTimeTable() }");
        proc.registerOutParameter(1, Types.INTEGER);
        proc.execute();
        int returnValue = proc.getInt(1);
        System.out.println(returnValue + "");
//      conn.close();
      }


      public static Connection getMySqlConnection() throws Exception {
        String driver = "com.mysql.jdbc.Driver";
        String url = "";
        String username = "";
        String password = "";

        Class.forName(driver);
        Connection conn = DriverManager.getConnection(url, username, password);
        return conn;
      }
    }

When I run this code I see a Exception in thread "main" java.sql.SQLException: Parameter index of 1 is out of range (1, 0) , why ?

This procedure return :

My procedure ;

    join mpk_timetable t ON( bst.timetable_id = t.timetable_id )
    join mpk_timetable tt ON ( t.linelogin_id  = tt.linelogin_id AND t.line_id = tt.line_id AND t.brigade = tt.brigade AND t.rate = tt.rate 
        and t.schedudle_id = tt.schedudle_id)
    LEFT JOIN mpk_busstop bs ON (bs.busstop_id = tt.busstop_id)
    LEFT JOIN mpk_busstate bt ON( bst.busstate_id = bt.busstate_id );

END

Answer 1

You need to specify the parameter in your call String:

CallableStatement proc = connection.prepareCall("{ call LCD_GetDispInfoAllTimeTable(?) }");

Notice that ? , it says that there is a parameter to be set. Now it knows that there is a parameter to be set, just like methods in Java or some other language. If you wanted to use multiple parameters you can write multiple ? , like: ...LCD_GetDispInfoAllTimeTable(?, ?, ?) .

Answer 2

as far as your procedecure declaration is concerned, its code is:

 CREATE DEFINER=`root`@`%` PROCEDURE `LCD_GetDispInfoAllTimeTable`()
 BEGIN
 SELECT bs.name as bsName, tt.busstoptype as bsType, tt.time as ttTime,
 bs.longitude as lon, bs.latitude as lat, tt.timetable_id as ttID, 
 Bus_Stop

where the procedure definition does NOT contain any parameter definition, so setParameter or registerOutParameter, cannot be applied for this procedure
