I wanted to report the same issue but my use case is the following:

insert into TABLE_A(id) values (:id)
returning RDB$DB_KEY into :t_dbkey;

and "t_dbkey" is always null.

Tested with Firebird 2.1 RC2 and RC1

We have two different problems here.

Test case for the original bug report in V2.0.3:

-------------------------
SQL> create table t (n integer)!
SQL> create table x (c char(8) character set octets)!
SQL> create trigger t_ai for t after insert
CON> as
CON> begin
CON> insert into x values (new.rdb$db_key);
CON> end!
SQL> insert into t values (1) returning rdb$db_key!

DB_KEY

8200000001000000

SQL> select rdb$db_key from t!

DB_KEY

8200000001000000

SQL> select * from x!

C

8200000001000000

SQL> insert into t values (2) returning rdb$db_key!

DB_KEY

8200000002000000

SQL> select rdb$db_key from t!

DB_KEY

8200000001000000
8200000002000000

SQL> select * from x!

C

8200000001000000
8200000001000000
-------------------------

You see in the last select, RDB$DB_KEY in after insert trigger returned incorrect value.

In V2.1 it returns NULL. Both are incorrect, but V2.0.3 is more problematic here.

About the problem with RETURNING, I'll create another ticket.
