Classic ASP and MS Access Batch Update - asp-classic

Question

I am using the following code to update an Access Database with Classic Asp:
<%# Language=VBScript %>
<% Option Explicit %>
<%
Response.Buffer = True
'First, we need to get the total number of items that could be updated
Dim iCount
iCount = Request("Count")
'We need to obtain each cost and ID
Dim strstudent, strcourse, strgrade, strcomments
'We will also need to build a SQL statement
Dim strSQL
Dim conn
set conn=server.CreateObject("ADODB.connection")
conn.ConnectionString="provider=Microsoft.jet.OLEDB.4.0;data source=C:\db\agsystem.mdb"
conn.Open
'Now, we want to loop through each form element
Dim iLoop
For iLoop = 0 to iCount
'student data
strstudent = Request(iLoop & ".Student")
'course data
strcourse = Request(iLoop & ".course")
'grade
if isNull(Request(iLoop & ".grade")) or Request(iLoop & ".grade")="" then
strgrade="null"
else
strgrade= Request(iLoop & ".grade")
end if
if isNull(Request(iLoop & ".comments")) or Request(iLoop & ".comments")="" then
strcomments=null
else
strcomments=Request(iLoop & ".comments")
end if
strSQL = "UPDATE testing SET semester2 = " & strgrade & ", commentss=" & "'" & strcomments & "'" & " WHERE newstudentid = " &"'"& strstudent&"'" & " and Courseid = " & "'"& strcourse & "'"
conn.Execute strSQL
Next
conn.Close
Set conn = Nothing
Response.Redirect "protected.asp"
%>
The problem is that when tested in the server it updates without any issues. But when access from a wireless network it won't update.
The target table to update has about 27,000 records
I need to know what I'm doing wrong or if there is another approach.

Answer 1

I found the error after carefully analyzing the situation.
Records in primary key that have spaces for example '2 OR 13' will not update. But records without spaces in primary key like '2CEN13' updates perfectly. I did not had time to solve it in my asp code, so i edited all records with spaces and that solve the problem.
