I’m just getting my head around insert statements today after getting sick of cheating with Dreamweaver’s methods to do this for so long now (please don’t laugh).
One thing I’m trying to figure out is how to get the ID value of a newly inserted record so I can redirect the user to that page if successful.
I have seen some examples which talk about stored procedures, but they’re double dutch for me at the moment and I’m yet to learn about these, let alone how to use these from within my web pages.
Summary
How do I, using my code below retrieve the record ID for what the user has just inserted.
Workflow
Using a HTML form presented on an ASP page (add.asp), a user will submit new information which is inserted into a table of a database (treebay_transaction).
On pressing submit, the form data is passed to another page (add_sql.asp) which takes the submitted data along with additional information, and inserts it into the required table.
If the insert is successful, the id value of the new record (stored in the column treebay_transaction_id) needs to be extracted to use as part of a querystring before the user is redirected to a page showing the newly inserted record (view.asp?id=value).
Sample code – add_sql.asp
<!--#include virtual="/Connections/IntranetDB.asp" -->
...
<html>
<body>
<%
set conn = Server.CreateObject("ADODB.Connection")
conn.ConnectionString = MM_IntranetDB_STRING
conn.Open ConnectionString
...
sql="INSERT INTO treebay_transaction (treebay_transaction_seller,treebay_transaction_start_date,treebay_transaction_expiry_date,treebay_transaction_title,treebay_transaction_transaction_type,treebay_transaction_category,treebay_transaction_description,treebay_transaction_status)"
sql=sql & " VALUES "
sql=sql & "('" & CurrentUser & "',"
sql=sql & "'" & timestampCurrent & "',"
sql=sql & "'" & timestampExpiry & "',"
sql=sql & "'" & Request.Form("treebay_transaction_title") & "',"
sql=sql & "'" & Request.Form("treebay_transaction_transaction_type") & "',"
sql=sql & "'" & Request.Form("treebay_transaction_category") & "',"
sql=sql & "'" & Request.Form("xhtml1") & "',"
sql=sql & "'3')"
on error resume next
conn.Execute sql,recaffected
if err<>0 then
%>
<h1>Error!</h1>
<p>
...error text and diagnostics here...
</p>
<%
else
' this is where I should be figuring out what the new record ID is
recordID = ??
' the X below represents where that value should be going
Response.Redirect("index.asp?view.asp?id='" & recordID & "'")
end if
conn.close
%>
</body>
</html>
Run this after your execute statement and before you close your connection:
