    Default Type Mismatch While Deleting Records

    I have a basic ASP page that collects two variables from a form. These 2 variables are used in the Query String to find the record to delete. However I keep getting a data type mis-match error when I try to delete a valid record. I used "Foward only", "Dynamic" and "Dynamic" along with "Optimistic" but nothing seems to work. By the way, this is the line that the error says it is occuring.<BR><BR>Please help!

    The data type mismatch is related to the delete statement: ex:<BR>delete from myTbl WHERE numfield=&#039bob&#039<BR>&#039 and numfield is numeric will result in a mismatch<BR>make sure your WHERE is comparing numbers to numbers, text to text and using the correct syntax.<BR>If you can&#039t get it to work, please post the query causing the error.<BR>

    Is Resnum a text column or a numerical one? If it is a number, ie Integer, then drop the single quotes:<BR><BR>Query = "SELECT * FROM project WHERE (((Resnum)=" & resnum & ") and ((Lname)=&#039" & lastname & "&#039));"<BR>

    Try out putting the Query string: response.write Query and cut and paste it off your web page into the Access SQL query page and run it there... see what errors it returns.<BR><BR>Also you could (in such a simple query), remove the parenthesis from the code Access writes – works the same and is easier for us to parse.<BR>
