INSERT, and get the auto-incremented value

Question

Consider the following table:

create table language (
    id integer generated always as identity (START WITH 1, INCREMENT BY 1),
    name long varchar,
             


        

Answer 1

You could execute this statement (NB, not 100% sure this syntax is correct for Derby:

SELECT TOP 1 id FROM language ORDER BY id DESC

To find the last inserted ID.

Alternative for Derby:

SELECT MAX(id) from language

Obviously this will only be accurate if no other inserts (including inserts by other users) have happened between your insert and select.
