Question

How to display result of oracle database query in JFrame?
This is part of my code:
String username, password;
          DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
          OracleConnection conn = DriverManager.getConnection(String url, String username, String password);
Statement s= conn.createStatement();
ResultSet q= s.executeQuery("SELECT A, B, C FROM TABLE X");
Forget what url, username & password are. Is there any problem with my code?
What should be next if I want to display result of the query in a table in JFrame?Thx !

How to create JTable with unknown no. of rows? How to get no. of rows of a query?
I saw the demo of creating JTable on java.sun.com but the the table has a certain no. of rows which is not applicable to my case.
Suppose the result of query is a table with 3 attributes so there are 3 columns in the table.
R contains the result of the query.
Should it be something like this if I want to create JTable of the query?
How to make n rows of {R.getString(1),R.getString(2),R.getString(3)};?
public SimpleTableDemo() {
super(new GridLayout(1,0));
String[] columnNames = {"A",
"B",
"C",
while (R.next())
// content of a row
Object[][] data = {R.getString(1),R.getString(2),R.getString(3)};
I can't run it because I still can't debug my code which is said before.
Thx!
