Sum function on Sql display on a Jtable

Question

Hi,
I'm trying to add up the values of a column on a Jtable and somehow display the Total. I have been trying to do the query by using a join on sql. Here is the code:
private void getTotal()                         {             Connection con = getConnection();             try{                 String sql = "SELECT Item.Item_price" +                         "FROM Item INNER JOIN [Order] ON Item.Item_ID = Order.Item_ID" +                         "SUM(Item_price) Where Order.Table_number = " + Integer.parseInt(tableNumber)+";";                 PreparedStatement pStmt = con.prepareStatement( sql, ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE );                 ResultSet rs = pStmt.executeQuery( );                 DefaultTableModel tableModel = new DefaultTableModel();                 tableModel.addColumn("Item_price");                 Object [] row = { rs.getObject(1)};                 tableModel.addRow(row);                 con.close();                 jTable1.setModel(tableModel);                                             }                   catch(Exception e)     { System.out.println(e);     }         }
Does anyone know a good method of doing this?
Thanks.

Dear Antony Gitonga  
It's not Table sum.
Plaese see the where condition, it will take only the current father and sum the quantity.
Plaese save the query in query manager and assign it in formated search and try.
select sum(T1.U_Base_Qty) From OITT T0,ITT1 T1
where
T0.code=T1.father and
T0.code = $[OITT.Code]
