It looks like the query that you're attacking isn't prepending and
appending quotes to your input. The string build probably looks a lil'
sumthin' like this:

Query = "SELECT FieldOne, FieldTwo, FieldThree FROM TableName WHERE PageID =
" & strPageID

    This means that there is no need to use quotes in order to perform a
successful injection. So, try something like this:

http://www.server.com/page.cfm?page_id=9999 UNION SELECT OtherField FROM
OtherTable WHERE 1=1

    Hopefully this will return an error complaining about an invalid table
name, or at least another error that may give you a better idea of what the
web application is doing with your argument.

It
