Retrieve data from SQL database and put into a table

Question

Hi all, i encountered this error while trying to create a table in 1 of my panels:
C:\Documents and Settings\L311c01\Desktop\FYPJ Java2\RFIDLogistics.java:25:{color:#ff0000} cannot find symbol
symbol : class ResultSetTable
{color}location: class jdbc_bible.part2.RFIDLogistics
private static ResultSetTable model = new ResultSetTable();
^
C:\Documents and Settings\L311c01\Desktop\FYPJ Java2\RFIDLogistics.java:25: {color:#ff0000}cannot find symbol
symbol : class ResultSetTable
{color}location: class jdbc_bible.part2.RFIDLogistics
private static ResultSetTable model = new ResultSetTable();
I understand that " cannot find symbol class ResultSetTable means that i need to import something which has this ResultSetTable. I suppose my imports are sufficient and i think the error is with the package that i included.
This package was taken from an example in a book named java database programming bible, so i assumed it is reliable and i use it for my insert statement, which had a DataInserter.
Could someone plz help me with this? Thanks alot in advance.
Here are the codes:
{color:#ff0000}package jdbc_bible.part2;{color}

import javax.swing.*;
import java.util.Vector;
import javax.swing.table.AbstractTableModel;

import javax.swing.event.*;
import java.awt.event.*;
import javax.swing.border.*;
import sun.jdbc.odbc.JdbcOdbcDriver;
public class RFIDLogistics extends JFrame{
//Components
// public SimpleClock clock;
private static JTable jt;
private static ResultSetTable model = new ResultSetTable();
some codes
{color:#ff0000}try
{{color}
{color:#ff0000} DataInserter inserter = new DataInserter();
String SQLCommand = "INSERT INTO " + flstr + " (Item_ID,Location_ID) VALUES ('"+Item_ID1+"','"+Location_ID1+"')";
String SQLCommand2 = "UPDATE Location SET Item_ID = '"+Item_ID1+"' WHERE Location_ID = '"+Location_ID1+"'";
inserter.execute(SQLCommand);
inserter.execute(SQLCommand2);
{color} JOptionPane.showMessageDialog(null, "Successful!");

If you would like to try if my table can extract, here are the sample codes, just change ur database name which is highlighted in green, and the table name in blue.
Codes:

import sun.jdbc.odbc.JdbcOdbcDriver;
public class sample1{
private static JFrame frm;
private static JTable jt;
private static ResultSetTable model = new ResultSetTable();
public static void main(String args[]){
String query = "SELECT * FROM {color:#00ccff}Forklift1{color}";
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:{color:#00ff00}RFID Logistics{color}");
PreparedStatement pstmt = con.prepareStatement(query);
ResultSet rs= pstmt.executeQuery();
// display the data in jtable
jt = new JTable();
model.setResultSet(rs);
jt.setModel(model);
frm = new JFrame("Sample");
frm.setSize(400,400);
frm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frm.add(jt);
frm.setVisible(true);
}catch(ClassNotFoundException sqle){
System.out.println(sqle);
}catch(SQLException sqle){
System.out.println(sqle);

Answer 1

public JTable populateTable()
  String[] colNames = new String[] {"ID","NAME","SURNAME"};
  return new JTable(getSQLData(), colNames);
public Object[][] getSQLData()
  stmt = conn.createStatement();
  ResultSet rs = stmt.executeQuery("SELECT [ID], [NAME], [SURNAME] FROM [USERS]");
  Object[][[] out = new Object[rs.getFetchSize()][3];//Not sure on getFetchSize but it should work
  int i = 0;
  while(rs.next())
    out[0] = rs.getInt(1);
out[i][1] = rs.getString(2);
out[i++][2] = rs.getString(3);
return out;
The above code will create a JTable with the data retrieved from the DB
