Search for data within a database table

Question

Hi everyone :)
I'm trying to make it so that the user can search for a record by id #. So, i made an input dialogue thing so the user can enter a record #. Basically, i want the data to appear in their textboxes based on the record # inputted by the user. My attempt is shown below, and when I run it, I get this:
java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression.
Here's my code:
public JButton getSearch()
          if (search==null)
               search = new JButton("Search Database");
               search.addActionListener
                    new ActionListener()
                         public void actionPerformed(ActionEvent ae)
                              try
                                   String str_rec =
                                        JOptionPane.showInputDialog(
                                             getFrame(),"Enter Record No");
                                   int recNo = 0;
                                   try
                                        recNo =
                                             Integer.parseInt(str_rec);
                                   catch (NumberFormatException nfe)
                                        return;
                                   String select = "SELECT studId,studFirstName,studLastName " +
                                   "FROM Students " +
                                   "WHERE studId = '" + recNo + "' ";
                                   Statement statement = getConnector().getConnection().createStatement();
                                   ResultSet result = statement.executeQuery(select);
                                   System.out.println(recNo);
                                   getView().getId().setText(str_rec);
                                   getView().getFirstName().setText(result.getString("studFirstName"));
                                   getView().getLastName().setText(result.getString("studLastName"));
                              catch (Exception e)
                                   e.printStackTrace();
          return search;
     }I hope I explained everything properly. If you could please help me, I'd very much appreciate it.
Thanks in advance! :)

Answer 1

"WHERE studId = '" + recNo + "' ";Why are you putting quote marks around a number? What type of database column is studId? Probably a numeric type (not character), right? Quotes go around string/character stuff, not numeric stuff.
