Default Chapter 15 (Bid.asp)

Hello, I am muddling my way through this chapter and have encountered a few problems but solved them through thorough detective work. Usually it is a punctuation or missing quote. This time I seem to have hit a wall.

This is the error I am getting now in my debugging process. I found some others and corrected them, but this one is stumping me:

Error Type:
Microsoft JET Database Engine (0x80040E14)
Syntax error (missing operator) in query expression 'ItemID ='.
/aspfiles/bid.asp, line 18

I am even getting this error with the book code. I checked my Access file and nothing seems to be amiss. All headers are written correctly (i.e. "ItemID" not "Item ID")

Here is the code with the offending line. The error seems to be pointing to the 'strSQL = "SELECT * FROM Item...." line.
<%
    dim rsItem, strItemName, strDescription
    Set rsItem = Server.CreateObject("ADODB.Recordset")
    strSQL = "SELECT * FROM Item WHERE ItemID =" & Request("Item")
    rsItem.Open strSQL, objConn
    strItemName = rsItem("ItemName")
    strDescription = rsItem("Description")
    rsItem.Close
    set rsItem = Nothing

    dim rsBids
    set rsBids = Server.CreateObject("ADODB.Recordset")
    strSQL = "SELECT * FROM Bid WHERE ItemID =" & Request("Item") &_
        " ORDER BY TimeStamp DESC;"
    rsBids.Open strSQL, objConn
%>
<center><h1> Wrox Classifieds<br>Bidding for <%= strItemName %><h1><center>

Any Suggestions? BTW, I am assuming I will get a similar error when the next strSQL line is executed ("SELECT * FROM Bid...")

Thanks in advance for your help.


Thanks,
JB977

Hi there,

It looks like Request("Item") does not have a value. Should it get that from a previous page? Look at the SQL statement to know for sure. To do that, make the following changes to your code, and post the output from the Write statement to this forum:
Code:
Set rsItem = Server.CreateObject("ADODB.Recordset")
strSQL = "SELECT * FROM Item WHERE ItemID =" & Request("Item")
Response.Write("SQL is " & strSQL)
Response.End
rsItem.Open strSQL, objConn
This should result in the SQL statement being written to the browser, so you can see if it is a valid SQL statement.

Cheers,

Imar

Thanks for the tip. I will try that and let you know what the results were. BTW the Request("Item") seems to point to the Access table "Item" correct? if so it is named properly since I checked w/ the other pages like browselistings.asp and it calls up the info from the table.

Stay tuned for the results.

Thanks,

Hmmm,

Got it. I think I was supposed to go from the browse listings page and click on a item---as per the books instructions. oops. Thanks for your help anyways. Gotta read things a little closer I guess. (embarrassed)

I am almost done with the chapter so I should be ok from here on. Once I start applying what I learned, I might be back.



Thanks,

Request("Item") does not point to something in the database, but to a variable retrieved from a page submitted to the page you're using it on.
When you have a page with a <form> tag that has a method set to GET or POST the page will submit to another page (or itself). You can then use Request(NameOfFormElement) to retrieve the value of the form element.

It's also possible to pass values through the querystring directly, e.g. <a href="MyPage.asp?ITEM=4">Click</a>
This will sent the QueryString variable to the MyPage.asp page where you can retrieve it with Request("ITEM").

It's usually a good idea to check for the presence of Request("Item") and other variables, before you execute your query, to prevent errors like this, e.g.:
Code:
If Len(Request("Item")) = 0 Then
  Response.Write("Sorry, you cannot access this page directly")
Else
  ' Request("Item") looks good, so continue
End If
HtH,

Imar

Is this related to the original post you replied to? If not, you may be better off starting a new topic.

What do you want us to tell "that is true"? Are you having problems with your code?
