Hello experts.

Now with a query:
<cfquery datasource=#dsn#>
INSERT into test1,test2
VALUES ('#form.test1#','#form.test2#')

if you know you will be using Msft SQL you can just do this:

<cfquery name="insertTest" datasource=#dsn#>
INSERT into test1,test2
VALUES ('#form.test1#','#form.test2#');
SELECT @@identity as newID;
</cfquery>

Then refer to your new variable as:
#insertTest.newID#

If you are using mySQL, you can use:
SELECT last_insert_id() AS newID

If you are developing a component, I think you still have to do the old insertQry/selectQry wrapped in a cftransaction.

One more note.  You can always create a sproc in SQL that inserts the values and returns the ID or an error and your CF code can act accordingly.  That's how we do it at my company.  Check out http://www.adobe.com/devnet/coldfusion/articles/stored_procs.html (listings 3,4, and 5 for more info if you want to go down that path)

sorry, when i said "developing a component," I meant a component that other developers could use... something you would post for download for instance that has to be DB independent.

Is this working in MySQL too.
Can i make the insert, and on the same page get the art_id that was generated and than pass this with a session to the next page?

the full code for mySQL would be (note the last line of the cfquery):

<cfquery name="insertTest" datasource=#dsn#>
INSERT into test1,test2
VALUES ('#form.test1#','#form.test2#');
SELECT last_insert_id() AS newID
</cfquery>

then you would do:
<cfset session.variableName = insertTest.newID />
if you wanted it in a session.
