Dica para visualizar os registros de uma tabela

Este exemplifica o acesso ao banco de dados dentro da própria página

<%@ page import="java.sql.*" %>

Usado para importar as classes necessárias



<%! ResultSet rs = null;%>
Declara um variável do tipo ResultSet para guardar os resultados de um pesquisa ao banco de dados



rs = s.executeQuery("select * from customer");
Guarda os resultdos da pesquisa em rs


while (rs.next()) {
O método next retorna true enquanto houver registros dentro de rs



<td width="20"><%= rs.getInt(1) %></td>
Acessa o primeiro campo do registro com inteiro



<td width="70"><%= rs.getString(2) %></td>

Acessa   o segundo campo comoString
