Question

I want to use an integer value in a TextField. In the below code I am retrieving integer value from table into textfield3. When I use getInteger(2) it is giving error. So what would be the alternative. If parsing is the solution (e.g. .toString) how is it to be implemented in this approach?

TextField3 = new TextField("Amount: ",r.getString(2));
add(TextField3);

This is what I am exactly trying to do

try
{
    //Open or create the database
    Database db = DatabaseFactory.openOrCreate("database1.db");    

    //Retrieval
    Statement statement1 = db.createStatement("SELECT date,name,amount,narration FROM Bills where id='"+TextField00.getText()+"'");
    //This is one text field to accept id value
    statement1.prepare();
    statement1.execute();

    Cursor c = statement1.getCursor();
    Row r;

    while(c.next())
    {
        r = c.getRow();
        TextField5 = new TextField("Date: ",r.getString(0));
        add(TextField5); 

        TextField2 = new TextField("Customer Name: ",r.getString(1));
        add(TextField2);

        TextField3 = new TextField("Amount: ",r.getString(2));
        add(TextField3);

        TextField4 = new TextField("Narration: ",r.getString(3));
        add(TextField4);
    }

    //statement1.prepare();
    //statement1.execute();       
    statement1.close(); 
    db.close();
}
catch( Exception e ) 
{         
    System.out.println( e.getMessage() );
    e.printStackTrace();
}

Hope it aids your understanding.

Answer 1

Try this line,

TextField3 = new TextField("Amount: ", r.getInteger(2) + "");

Instead of

TextField3 = new TextField("Amount: ",r.getString(2));
