Insert into two tables

This seems like such a common place procedure that I figure there had
to be a "right" way to do it.

I've got two tables, orders and order_items. orders has a primary
key "ordersid" and order_items has a foreign key, orderid (which
obviously references orders.ordersid)

Say I want to create a new order and put some items into it. If
I use an autoincrement field I could just:

  INSERT INTO orders VALUES ( ... );

And then I need to get the orderid I just created to create
new records in the orderitems table So am I supposed to 
immediately do a:

  SELECT ordersid FROM orders ORDER BY ordersid DESC LIMIT 1;

And then get the value, and then do inserts in the order items
table? Surely there's some way to wrap this all up into a 
nice little procedure or something.

Thanks----

I've just figured out how to display the PostgreSQL version number in
Cold Fusion. Here's the code:
<CFQUERY NAME="getversion" DATASOURCE="yourdatasource"> SELECT
version();</CFQUERY>
<CFOUTPUT>#getversion.version</CFOUTPUT>
Best regards,
