java mysql scala jdbc

1) Instead of PreparedStatement use Statement

2) After executing query in ResultSet, extract values with the help of rs.getString() as :

Statement st=cn.createStatement();ResultSet rs=st.executeQuery(sql);while(rs.next()){    rs.getString(1); //or rs.getString("column name");}

java mysql scala jdbc

use further as

rs.getString(1);rs.getInt(2);

1, 2 is the column number of table and set int or string as per data-type of coloumn
