java.sql.SQLException：列位置'1'超出範圍

我有這個錯誤，我不明白，有人可以告訴我我做錯了什麼嗎？java.sql.SQLException：列位置'1'超出範圍

java.sql.SQLException：列位置'1'超出範圍。此ResultSet的列數爲'0'。

public Object[][] searchFunction(String searchWord, String loginId) { 
    Object[][] data = new Object[5][6]; 
    String[] tableName = {"subject", "sender", "recipient", "label", "message"}; 
    int nr = 0, i = 0, q = 1; 
    boolean hasRows = false; 
    for(int j = 0; j<5; j++) { 
     try {  
      PreparedStatement prepareStatement = con.prepareStatement("SELECT * FROM messages WHERE sender = ? AND " + tableName[j] + " LIKE '%Done%' ORDER BY id ASC");  
      prepareStatement.setString(1, loginId);  
      rs = prepareStatement.executeQuery(); 
      while (rs.next()) { 
       hasRows = true; 
       boolean check = true; 
       int id = rs.getInt("id"); 
       int priority = rs.getInt("priority"); 
       String recipient = rs.getString("recipient"); 
       String labelDb = rs.getString("label"); 
       String subject = rs.getString("subject");  
       String date = rs.getString("date");  
       String stars = setPriorityStars(priority); 

       for(int k=0; k<i+1; k++) { 
        Object idObj = (Integer) id; 
        if(data[k][0] == idObj) check = false; 
       } 

       if(check == true) { 
         data[i][0] = q; 
         data[i][1] = stars; 
         data[i][2] = recipient; 
         data[i][3] = labelDb; 
         data[i][4] = subject; 
         data[i][5] = date; 
         i++; 
         nr++; 
         q++; 
        } 

      } 
      if(hasRows == false) { 
      data = getInbox(loginId); 
      JOptionPane.showMessageDialog(null, "There is no fields that includes " + searchWord); 
      break; 
      } 
     } catch(Exception ex) { 
      System.out.println(ex); 
     } 
    } 
    System.out.println("Found " + nr + " results"); 
    return data; 
}
