Hi

I am working on webreport that will display data pulling data from database below is the code.
When data is displayed on web it should display in form format so that it can be updated by user.
It is not just a report but its a form based report

<TABLE WIDTH="100%" BORDER="+5" >
    <TR > <h5>
    <%
    for(int i = 1 ; i <= rsmd.getColumnCount() ; i++) {
    %> </h5>
    <TH>
    <%= rsmd.getColumnLabel(i) %>
    </TH>
    <% } %>
    </TR>  
<% while(rs.next()) { %>  
<form method=post action = saveForm()>
<input type=text value = rs.getString(1)>
<input type=text value = rs.getString(2)>
<input type=text value = rs.getString(3)>
<input type=submit name=save>
</form>
   <% } %>    

I am want to something like above code where data will be displayed in text boxes so that user can update records.
I am not sure how to do it. Can anyone post sample code which have functionality for similar requirement.
Please give me sorce code that will explain me what exactly what I can do.

Please check below code something similar that wouls help me to update the values

<%@ page import="java.sql.*"%>
<%
            Connection con=null;
            Statement st=null;
%>
<%
            DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
            con=DriverManager.getConnection("jdbc:odbc:emp");
            st=con.createStatement();
%>

<html>
<head><title>:: Display ::</title></head>
<body bgcolor=goldenrod>
<form method=get name=display action="udate.jsp" >
      <center><h1>Update</h1></center>
      <br>
      <hr>
      <br>
      <%@ include file="conn.jsp" %>
      <%
      try
        {       
            int nus = Integer.parseInt(request.getParameter("no"));
            ResultSet rs = st.executeQuery("select * from emp where empno="+nus+"");
      if(rs.next())
      {%>
      <table bgcolor=khaki border=1 align=center>
      <tr><th bgcolor=seablue>Emp ID</th><td bgcolor=silver><input type=text name=id value=<%= rs.getInt(1) %>></td></tr>
      <tr><th bgcolor=seablue>Emp Name</th><td bgcolor=silver><input type=text name=name value=<%= rs.getString(2)%>></td></tr>
      <tr><th bgcolor=seablue>Emp Salary</th><td bgcolor=silver><input type=text name=sal value=<%= rs.getInt(3)%>></td></tr>
      <tr><th bgcolor=seablue></th><td bgcolor=silver><input type=submit value=Update name=opt><input type=submit value=Delete name=opt></td></tr>
      </table>
      <%}      
      }catch(Exception e){e.toString();}
      %>
      
</form>      
</body>
</html>
>>>>select * from emp where empno="+nus+"");

the above query would retrieve the records from database. For update you would need "update"  query.

see this

http://java.sun.com/docs/books/tutorial/jdbc/basics/updating.html
and if you want to retrieve records using "select" query this would help

I am sorry I think question was not clear. I am looking for example that will help me to display records from database inform of rows. I am able to display the data in tablular format. but I have some columns that will be displaying textboxs so that user can updates the records when diplayed.

example

EMPNO                     EMPNAME                DOB
123                         _________              ________
1234                       _________              ________
236                         _________              ________

_______ are nothing but textboxs

Syntax:
<tr><td>rs.getString(empno)</td>  <td><input type="text" value=rs.getstring(empname)></td> ....</tr>
<tr><td>rs.getString(empno)</td>  <td><input type="text" value=rs.getstring(empname)></td> ....</tr>
<tr><td>rs.getString(empno)</td>  <td><input type="text" value=rs.getstring(empname)></td> ....</tr>

this will help in getting empname from user as input value.
So that webreport will be something like grid format with textboxs for input so that user can update information when it is dislayed.
As multiple records are displayed it should update multiple records when user clicks on update.
I am looking for good example..
