multiple delete using checkbox - error
Hi,
Am using the delete events steps to construct a admin page similare to the GlobalsoccerEvents page, and am at the delete page, I have edited the page to meet my fields in the database but am getting error message:
Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E14)
[Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression 'NewsID IN ()'.
./deleteNews.asp, line 12
-----------------delete page code------------------
<%
if(Request("checkboxName") <> "") then commDelete__intRecordsIDs = Request("checkboxName")
%>
<%
set commDelete = Server.CreateObject("ADODB.Command")
commDelete.ActiveConnection = MM_loggingdatabase_STRING
commDelete.CommandText = "DELETE FROM Newstbl WHERE NewsID IN(" + Replace(commDelete__intRecordsIDs, "'", "'") + ")"
commDelete.CommandType = 1
commDelete.CommandTimeout = 0
commDelete.Prepared = true
commDelete.Execute()
%>
---------------end of code--------------------------------
where am I going wrong?

Hi there,
It looks lime commDelete__intRecordsIDs doesn't have a value when you execute the code. That in turn means that Request("checkboxName") probably doesn't have a value. Are you sure you have a check box called checkboxName (nice name BTW) in the previous form?
Your code uses some defensive mechanism to make sure that checkboxName has a value. However, you then execute the command outside the IF block. Change it to this:
If Request("checkboxName") <> "" Then
commDelete__intRecordsIDs = Request("checkboxName")
set commDelete = Server.CreateObject("ADODB.Command")
' Rest of ADO code goes here
End If
This way, the Execute command is never called when there is no checkbox selected.
Does this help?

Take a look at this:
Code:
<input name="checkboxName" type="checkbox" id="checkboxName" value="<%=(RsNewstbl.Fields.Item("NewsID").Value)%>">
... later
<form action="deleteNews.asp" method="post" name="frmEvents" id="frmEvents">
Your checkboxes are declared outside the form, so they are never submitted to deleteNews.asp.
To fix this, move the opening <form> tag to right after <body> and move the closing </form> tag to right before </body>
That way, the entire page is wrapped inside the form tag, so all controls are submitted to the server and the dele will succeed.
Cheers,
Imar

Not really.
Do you do a Redirect after you deleted the records? If so, is the page you redirect to expecting a QueryString you're not passing?
