it is deleting the record set data & not the actual data storec on the database
Try this

mySql ="Delete from name where no=' "&id" '
Con.Execute mySql

dim mySQL

Set Conn=Server.CreateObject("ADODB.Connection")

myDSN="DSN=mydsn;uid=;pwd="

conn.open myDSN

Set rs=server.CreateObject("adodb.RecordSet")




id=TRIM(Request.Form("id"))

mySql ="DELETE from name where no=' "&id" '
Con.Execute mySql

Con.Close
Set Rs= Nothing
Set Con=Nothing

%>

The rest will be followed by the HTML code you are using. In case you still have problem with Html code let me know.

Although I am pretty sure all you really need to do is change the last line of your ASP code from rs.delete to "rs.delete adAffectCurrent", the following should also do the trick just in case:

Also...take a look at the back button in the HTML...

<!--delete.asp-->
<!--#include file="adovbs.inc"-->

<%

myDSN="DSN=mydsn;uid=;pwd="

dim id, rs, sqltext

id=trim(Request.Form("id"))
ID=cInt(id)

set rs=server.createobject("adodb.recordset")
sqltext="Delete FROM name where no=" & ID
rs.open sqltext, myDSN,1,3

rs.close
set rs=nothing

%>


<html>
<head>
</head>
<body>
 <center>
<H1> Maintenance </H1>
 </center>
<br><br>
<center>
<H2>
The record has been successfully deleted </H2>
<br><br><br>

<Input type="button" Value="Back" onClick="history.back(-1)">

</center>
</body>
</html>

i have tried but your code Jferry and Bimal but it is not working at all. what should i do now . it is updating and retrieving the records but is not deleting the values nor it gives any problem while running the scripts, except i have to change the quotes b/w &id  in your code.

Sorry...
The right code is this :

...
Set CONN = Server.CreateObject("ADODB.Connection")
CONN.Open "DSN=mydsn;uid=;pwd="
CONN.Execute "DELETE FROM NAME WHERE (NO=" & CStr(No) & ")"
CONN.Close
...
