Howto return ids on Inserts with Ibatis ( with RETURNING keyword )

Question

I\'m using iBatis/Java and Postgres 8.3. When I do an insert in ibatis i need the id returned.
I use the following table for describing my question:
CREATE TAB

Answer 1

Here is simple example:

        INSERT INTO objects(expression, meta, title,
        usersid)
        VALUES (#expression#, #meta#, #title#, #usersId#)
        RETURNING id

And in Java code:

Integer id = (Integer) executor.queryForObject("addObject", object);
object.setId(id);

This way more better than use :

1. It's simpler;
2. It have not requested to know sequence name (what usually hidden from postgresql developers).
