How to get the generated key from insert with Oracle

[Chris O'Connell]

So, I need to insert a User record.  I cannot change the database tables, so
I am stuck with the current behavior of my database.  On insert, there is a
trigger that selects a value from a SEQUENCE and updates the key with that
value.  I would like to return that value from the insert statement to my
java code.  I'm looking at the iBatis in Action book, and trying to figure
out how to do that.  I will include the parameter map I am using and the
<insert> statement below. To explain what you see below, the EMAIL field in
the database is unique, so if I create a new user with the provided email
address, I feel safe selecting that userID back out of the database based on
the email address.

However, this just feels clunky to me.  Is this the right way to do it?  Is
there a better way to get the new ID from the row I just created (given my
current constraint of not being able to change the database)?

Thanks,
Chris
