I don't think you need to worry about LAST_INSERT_ID so long as you have the same connection that inserted it. With IBatis this is not a problem.
"The last ID that was generated is maintained in the server on a per-connection basis. This means the value the function returns to a given client is the most recent AUTO_INCREMENT value generated by that client. The value cannot be affected by other clients, even if they generate AUTO_INCREMENT values of their own. This behavior ensures that you can retrieve your own ID without concern for the activity of other clients, and without the need for locks or transactions."
The paragraph above assumes that the "client" always holds onto the same database connection. In the case where a framework (i.e. Spring) is managing the database connections, perhaps using commons-dbcp, wouldn't it be possible that it would grab a connection from the pool, execute the insert, then release it back to the pool?
