Hi,
I'm using the following two snippets but keep getting a type mismatch error

Listing Page
"<TD BGCOLOR=""" & BCol & """ ALIGN=""right"">" & "<A HREF=""newsletter.asp?mode=deletemail&id=" & rs("MailHistoryID") & """>" & "Delete" & "</A>" & "</TD></TR>" & vbcrlf

Delete Page
If Request.QueryString("mode") = "deletemail" Then

intMailHistoryID = Request.QueryString("id")
strSQL = "DELETE * FROM MailHistory WHERE MailHistoryID = '" & intMailHistoryID & "'"

'Response.write intMailHistoryID
'Response.End

Conn.Execute(strSQL)

The response .write shows the value of the MailHistory id but the SQL won't execute because of the type mismatch.

Any help much appreciated.

If Mailhistoryid is integer then remove the single quotes

strSQL = "DELETE * FROM MailHistory WHERE MailHistoryID = " & intMailHistoryID

You have single quotes around an integer value. Single quotes specify a char value. Your type mismatch is from trying to set an integer column to a character value.

you must remove the star:

strSQL = "DELETE FROM MailHistory WHERE MailHistoryID = " & intMailHistoryID

looks like you've got good suggestions above.

General tip - print out sql statements that give you trouble. ie:

response.write vbcrlf & "<!-- SQL: " & strSQL & "-->" & vbcrlf

that will troubleshoot it for you most of the time.
