Uploading data in the table from mysql db, any help is welcome

Question

Hi, I have made a table with two columns, "Name" and "ID". Those are binded to contexts NameCtx and IDCtx. There are ten rows in table. What I need to do is upload Names and IDs from mysql database and fill those rows from 1 to 10 and I dont have much idea how to do this. Any tutorial, blog or your piece of code or tips will be most welcome. Regards, Balmer

Hi,
To access the My SQL db pl refer this thread
writing data form Webdyn Pro inputfield into MySQL db
Once the connection is done
Create a statement
Exeecute the sql statement
Iterate the resultset
populate the context
try{
              Connection conn;
              Class.forName("com.sap.dbtech.jdbc.DriverSapDB");
               String urlConn = "jdbc:sapdb://localhost/maxdb1"; //replace localhost and the maxdb1 with your server name and database.
               String username = "userID";
               String password = "password";
               conn = DriverManager.getConnection(urlConn, username, password);
               System.out.println("connected to DB...");
               //Change the select statement to that of yours
               Statement stmt = conn.createStatement();
               stmt.execute("select name,id from table1");
               //Result set
               ResultSet resultSet = stmt.getResultSet();
               //Iterate to populate the context that is bound to the table.
               while (resultSet.next())
                    //Change the element and node name to that of yours
                    IOrdersElement ordersElement = wdContext.nodeOrders().createAndAddOrdersElement();
                    ordersElement.setNameCtx(resultSet.getString(1));
                    ordersElement.setIDCtx(resultSet.getString(2));
            }catch(Exception e)
                 //handle the exception
