Hi Friend,

Try the following code.It will retrieve previous and next record from the database to the table.

<%@ page import="java.sql.*" %>
<% Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") ; %>

<HTML>
<FORM NAME="form1" METHOD="POST">
<%
int current = 0;
if(request.getParameter("hidden") != null) {
current = Integer.parseInt(request.getParameter("hidden"));
}

Connection connection = DriverManager.getConnection("jdbc:odbc:access", "", "");

Statement statement = connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
ResultSet rs =
statement.executeQuery("select * from departments");

if(current < 1){
current = 1;
}

rs.last();
int rows = rs.getRow();
if(current <= rows){
rs.absolute(current);
}
%>

<TABLE BORDER="1">
<TR>
<TH>Department Number</TH>
<TH>Department Name</TH>
</TR>
<TR>
<TD><INPUT TYPE ="text" name = "dept" value="<%= rs.getString("dept_Name") %>"/></TD>
<TD><INPUT TYPE ="text" name = "number" value="<%= rs.getString("dept_No") %>"/> </TD>

</TR>
</TABLE>
<BR>
<INPUT TYPE="HIDDEN" NAME="hidden" VALUE="<%= current %>">
<INPUT TYPE="BUTTON" VALUE="Previous Record" ONCLICK="movePrevious()">
<INPUT TYPE="BUTTON" VALUE="Next Record" ONCLICK="moveNext()">
</FORM>

<SCRIPT LANGUAGE="JavaScript">
<!--
function moveNext()
{
var counter = 0
counter = parseInt(document.form1.hidden.value) + 1
document.form1.hidden.value = counter
form1.submit()
}
function movePrevious()
{
var counter = 0
counter = parseInt(document.form1.hidden.value) - 1
document.form1.hidden.value = counter
form1.submit()
}
</SCRIPT>
</HTML>

Thanks
